20. Asterina belcheri.

 Port Jackson. 



21. Asterina calcar. 



22. Asterina cepheus. 



Asperiscus cepheus, M. ty Tr. Si/st. Ast. p. 41. 

 Asterina cephea, Perrier, p. 315. 



I follow Prof. Perrier in using Miiller and Troschel's specific name, 

 on the ground that, though Gray's name burtoni has the precedence 

 by two years, the " type " is not to be found, and the description is 

 useless for any purposes of identification. As cepheus is obviously a 

 proper name, I prefer to use it without making any alterations in 

 its termination. 



Thursday Island. 



23. Asterina gnnnii. 

 Perrier, p. 298. 



A small specimen from Port Molle. 



24. Asterina regularis. 



Verrill, Trans. Connecticut Acad. i. p. 250.

"What seems to be a young specimen of this species was also taken 

 at Port Jackson. 



25. Asterina (Nepanthia) brevis. (Plate VIII. figs. A, A'.) 

 Perrier, p. 321. 



As Prof. Perrier's description would appear to be based on a single 

 small dried specimen in the British Museum, I give the measure- 

 ments of two specimens preserved in spirit : — 



R = 32, 44; r=9, 12; or R=2'7 or 2*8 r, 

 and a figure of the largest specimen. 



Albany Island (8 fms., sand and mud) ; Thursday Island (4 fms., 

 coral). 



26. Patiria crassa, Gray. 

 Perrier, p. 326.
