BANNER INVERTEBRATE X ZOOLOGY, / Crurttcit f Contributions to the Knowledge of the Alpheid Shrimp of the Pacific Ocean Part XII. Collections from the Marshall and Caroline Islands1 Albert H. and Dora M. BANNER Department of Zoology, University of Hawaii, Honolulu, Hawaii This is the last of our projected series of studies on the systematics and distribution of the alpheid shrimp of the Central Pacific. It reports upon collec- tions made by the senior author at Eniwetok in 1957 and upon an extensive series of specimens loaned by the U. S. National Museum and the Alan Hancock Founda- tion that resulted from studies conducted by a number of investigators under the auspices of the Atomic Energy Commission and the Coral Atoll Studies of the National Academy of Science. A smaller collection from Arno in the Southern Marshalls was reported on in Part II of this series, and R. W. Hiatt's collection from Yap in the Carolines was reported on in Part IV. This is also the last of the studies that was completed at the time of the Hawaii Marine Laboratory fire in 1961 (Banner and Banner, 1962). Destroyed in the fire were the specimens, many on loan from the U. S. National Museum and the Hancock Foundation, the figures, and the finished manuscript. As with Parts IX, X, and XI we found the original rough draft sufficiently unburned that it could be reconstructed, although with some ommissions. In some cases the col- lectors were able to supply full duplicate data; in other the data, like the speci- mens, were lost. The senior author's Eniwetok collection was made under the AEC contract AT (29-2)-226; the study was supported in part by NSF grants G-3863, G-9937 and GB-3809 from the division of Systematic Biology, National Science Founda- tion. We also wish to acknowledge our appreciation of all of the collectors listed in the following pages, especially to Drs. Abbott, Bayer, Garth, Johnson, and Morrison. LOCALITIES First presented are the collections of the senior author listed with a BE prefix; following are loaned collections. Here to save space, the name of the collectors are abbreviated to the following code: 1 Contribution No. 330, Hawaii Institute of Marine Biology.

Following the code is the collector's numerical designation; in the case of the collections of Dr. Martin Johnson where he had assigned no numbers we have arbitrarly assigned numbers from 1-24. Geographical names were taken from the U. S. Board of Geographic Names decision, 1955. 145 150 155" 160' 165' 170 1 l t i 1 1 20 20 MARIANA < ISLANDS eSaipan 15 15 0 Guam MARSHALL ISLANDS * E";"eto!< Bikini .

From coral patch which was surrounded by sand; 30 meters from shore in 2 meters of water. BE 1 was from a head of dead Acropora sp., Vol. 4. December 1968 263 most specimens came from the base; BE 2 was from a head of Pocillopora meandrina; BE 3 was from a living head of Acropora, most specimens came from the base. BE 4. Parry Island, windward ocean reef. Collections made about 6-12 meters behind coral- line ridge in region of strong surge, slightly below low tide zone. Specimens came from consolidated heads of coral, masses of calcareous alga, and dead, overgrown coral heads. Inner portion of reef was seemingly devoid of alpheids. BE 5-8. Parry Island, lagoon side. Collection made on patch reef which rises from a sandy bottom located about 200 meters from the south end of the island. Specimens from six dead, overgrown heads of coral, four were of flat Acropora, one a massive Pontes and one a Pocillopora; the shrimp come from algae on the top, from spaces between the fronds and from holes in the bases. BE 7 was from dead coral resting on a sandy bottom. BE 8 was from dead and overgrown heads of a ramous Acropora. BE 9. Rigili Island, ocean reef flat. Collection made near the outer edge of the ocean reef flat, about 0.5 meter below low tide zone. Specimens from dead and overgrown head of flat Acropora. BE 10. Rigili Island, edge of inner lagoon of seaward reef. Collection made about 30 meters from shore, about 0.5 meters below low tide zone. Specimens came from two overgrown heads of Acropora, and one head of Pocillopora meandrina. BE 11. Parry Island, lagoon side. Collection made about one-third of length from the southern tip; the bottom was sand and about 2 meters deep. Specimens came from the overgrown heads of Pocillopora meandrina and bases of branching Acropora (BE 11a were specimens from holes occupied by Echinometra; BE lib were specimens from algal tubes.) BE 12-14. Arambiru-to, from channel between the island and ocean reef flat. At the stage of the tide collections were made, the channel was filled with swiftly flowing water running from the reef flat to the lagoon. BE 12. Specimens were from various species of coral, mostly dead, lying in 2 meters of water. BE 13 same as above but nearer shore. Water was about 0.6 meter deep (BE 13a, from tube of blue-green algae). BE 14. Located on inner reef flat in water 1 meter deep. This area was subject to strong wave and current action. Specimens were taken from one dead and one partially live head of a massive Porites, both coral with Echinometra in depressions, BE 15. Arambiru-to, lagoon side on sand bottom in water 1-2 meters deep. Specimens were taken from a few scattered heads of dead coral. BE 16, 19, 20. Igurin Island, cove on lagoon side. Evidently the area had some brackish water seepage from the islet; bottom bearing fine powder sand, which continued from near low tide zone to several feet deep; bottom covered with scattered heads of dead coral and boulders; there were some living coral heads at the side of the cove. BE 16 specimens were collected under boulders on sand beach. BE 19 specimens were from overgrown heads of Heliopora and Pontes', many specimens found in superficial tunnels, others in between the fronds and in tunnels in base (BE 19a from a Porites, 19b from a Heliopora). BE 20 was a revisit of BE 16; this time the beach was surveyed for a quarter of a mile, and specimens (largely A. strenuus and two species of Salmoneus) were found under almost all boulders larger than 0.3 meters in diameter. The boulders lay on a mixture of fine gravel and sand, or pure sand. BE 17, 18. Igurin Island, ocean side. BE 17 came from a coralline ridge which had only a slight surf under normal trade winds; ridge, about 0.5 meters above low tide zone, was smooth and consolidated, but with numerous burrows, a little over 1 centimeter in diameter and up to 20 centimeters long, which were twisting and had many branches connected to the sea through numerous regular ports; only one pair of shrimp in each burrow. BE 18, was in a back ridge trough, about 0.3 meters below low tide zone. Specimens found in dead bases of living coral, and in algal tubes between dead coral branches. BE 21, 22. Muti Island, off north end. Collection extended across broad ocean flat to the 264 Micronesica lagoon. BE 21, specimens from consolidated and smooth bottom, composed of dead and overgrown coral from 1 foot below low tide zone. BE 22 was closer to the lagoon, water about 2 meters deep with bottom mostly sandy; specimens from dead heads of Pocillopora. BE 23, 24, 26, 27. Parry Island, ocean reef off the marine laboratory. BE 23, from coralline ridge, and ends of surge channels, exposed about 0.3 meters above 0.0 tides; ridge dense and hard, very irregular and without the usual smooth algal surface; almost all specimens from superficial burrows, roofed over by calcareous algal sheets. BE 24, 27 came from the shallow (0.3 meter deep) back-ridge trough; specimens were from coralline algal masses around the edges of the trough. BE 26 mid-section of reef, 0.3 meter above 0.0 tide level; specimens came from burrows in the bases of dense tufts of worm tubes packed in the sand that rises above the consolidated reef surface. BE 25. Parry Island, southern tip, lagoon side. Conditions were parallel to BE 5; specimens collected from an overgrown head of massive coral. Almost all specimens came from shallow grooves and burrows in the superficial mat of algae. Collector and Locality and Date Notes Number Bikini Atoll BA 8 Prayer Is.
