A. H. CLARK : THE CRTNOIDS OF THE INDIAN OCEAN. 87 



Locality. — Amlaman Islands. — One rather small example with about one 

 hundred and sixty arms 90 mm. long. It agrees with specimens at hand from 

 the Philippine Islands. 



Other Records.— Banda, Moluccas; Philippine Islands ; Macclesfield Bank. 



Depth.— 17— 30 fathoms. 



COMASTER DELICATA. 

 Phanogenia delkata 1909. A. H. Clark, Proc. U. S. Nat. Mus., vol. 36, p- 393. 

 Habitat. — Philippine Islands. 

 Depth. — 49 fathoms. 



COMASTER NOV^GUINE^. 



Alecto novm-guimm 1841. J. MtJLLER, Archiv fur Naturgesch., 1841, i, p. 146. 

 Comaster jiovce-guinece 1908. A. H. Clark, Proc. U. S. Nat. Mus., vol. 33, p. 686. 

 Actinometra regalis 1894. Bell, P. Z. S., 1894, p. 396. 



Habitat.— Eidouma, New Guinea ; Ternate ; east coast of China ; Maccles- 

 field Bank ; Philippine Islands. 



Depth. — Littoral, and down to 49 fathoms. 



Remarks. — In the type at Leyden there are fifteen cirrus sockets, and one 

 segment of a single cirrus remains. This specimen has the same smooth appear- 

 ance as the specimen of Liitken's Actinometra stellata from Fiji in the Copenhagen 

 Museum. Compared with the specimen of typka at Leyden (described by Carpen- 

 ter) the only differences to be found are the lesser numbers of arms and the thinly 

 discoidal centrodorsal on which are cirrus sockets. It almost entirely lacks the 

 rough and spinous character of the Philippine specimens which heretofore I had 

 regarded as representing true novwguinecB. There is a strong possibility that it 

 may turn out to be synonymous with typica, in which case the Philippine form 

 would require a new name ; it might be appropriately called philippinensis.

Remarks. — One of the specimens recorded by Carpenter as •' Actinometra 

 parvicirra'-' in the "Challenger" report is in reality a specimen of 6'oma.ster 

 distincta ; the two species have also been confused by Professor Bell ; an
