288 THE SPONGES OF THE WEST-CENTRAL PACIFIC 



central portion of the lagoon. The other five came from very shallow water 

 and were collected while wading. The twelve are : 



1 Spongia officinalis. The local subspecies, common in the Marshalls, is 

 rare at Ponape and not reported elsewhere. The main species is cir- 

 cumequatorial. 



2 Haliclona korcma. I found a species in the Palaus which I have thus 

 named. Morrison found a sponge rather common at Bikini which is 

 like korema in the respects which still show in the long-preserved 

 specimens. On the other hand, such specimens might also fit some 

 other species nearly as well. Identification with the Palaus sponge is 

 made only with hesitation and with the comment that other identifica- 

 tions appear even more open to question than this one. 



3 Neopetrosia pandora. I did not find this conspicuous species anywhere 

 in the Marshalls. Morrison found it only once, and that was 50 meters 

 deep. It is abundant in shallow water (often barely below low tide) 

 throughout Ponape, Truk, and the Palaus. 



4 Adocia turquoisia. I found this at Majuro in the Marshalls and also 

 at Ponape, Truk, and the Palaus. It is not recorded elsewhere. 



5 Agelas mauritiana. I found this at Majuro, Ebon, and Ponape. Mor- 

 rison found it also at Eniwetok. Earlier records have been from the 

 Indian Ocean. 



6 Kieplitela antrodes. I found this at Likiep in the Marshalls, also at 

 Ponape, the Palaus, and Guam. It is not recorded elsewhere. 



7 Halichondria adelpha. The only other record is mine from Ebon. 



8 Hymeniacidon dystacta. I found one little specimen at Ebon. Morrison 

 found many at Bikini. These are all dubious specimens — not to be 

 allocated with confidence but apparently at least conspecific with each 

 other. 



9 Tet'hya actinia. I found this also at Ebon. Earlier records are East 

 Indian and West Indian (Bermuda). 



10 Hezekia walkcri. Morrison found this at Eniwetok. I found it com- 

 mon at Likiep and also at Ponape and the Palaus. It is not recorded 

 elsewhere. 



11 Cinachyra anstralicnsis. This may be a new, unique species of Cina- 

 chyra. It is put with australiensis only with reservation. Bullock's 1948 

 collections agree with the 1946 ones. Sponges that are certainly 

 australiensis have been recorded from Australia and the East Indies, 

 and I found it also at Ponape and Truk. 



12 Chondrosia chucalla. This is the only point of agreement between 

 Bikini and Ailing-lap-lap, where I found this Chondrosia. It is else- 

 where reported only from Australia. Yet it is a very dubious agree- 

 ment, because the long preserved specimen from Bikini was not such
