Pentaceropsis obtusata, Sladen, Chall. Rep., Aster. (1889), p. 351. 

 Loc. Blanche Bay. 



Several specimens were obtained of this rare species. Mr Sladen indicates very 

 briefly his reason for forming a new genus for the species, and the series at my 

 disposal is too short to justify my supporting or declining to support his view. 



23. Culcita. 



A small specimen from Sandal Bay is of very great interest, as it is, so far as 

 I know, the only example of its genus in which there is an imbrication of the 

 plates of the dorsal surface (see fig.). The bearing of this on the affinity of Culcita to 

 Asterina need not be insisted on.

Oral and aboral views of an undetermined specimen of Culcita from Saudal Bay, Lifu ; showing imbrication 

 of dermal plates on the dorsal surface. Diameter of specimen 13-5 mm.

Asterias carinifera, Lamk., Anim. s. Vert. ii. (1816), p. 556. 

 Gymnasteria spinosa, Gray, Ann. and Mag. vi. (1840), p. 278. 

 Gymnasterias carinifera, Sladen, Chall. Rep., Aster. (1889), p. 357, ibique citata. 

 Loc. Lifu. 



This is a species which appears to extend from the Red Sea to Panama, and 

 is often found in collections from the Pacific.

Asterias exigua, Lamk., Nat. Hist. s. Vert. ii. (1816), p. 554. 

 Asterina exigua, Sladen, Chall. Rep., Aster. (1889), p. 392, ibique citata. 

 Loc. Loyalty Islands. 



This widely spread species was well represented.
