ASTEllOIDEA. 
Asteriidee. Liitken (Vid. Medd. 1871, pp. 227-304, pis. 4 & 65 summary, pp. 
19-26) notices many known genera and species as follows : — Astropecteti is best 
distinguished irom Archaster by the want of an anus ; the difference in the shape 
of the ambulacra is less satisfactory. Astei'opecten velitaris, Mart., is really 
distinct from A. armatm. Ctenodiscus australis, Loven, Archaster tenuispinus. 
Dub. & Kor., and Choriaster graiiulatus, Ltk., are redescribed. Goniaster, Ag., 
will include the 3 subgenera Stellaster (^ — UorigaJia, Gray), Astrogonium, and 
Goniodiscus, and the following species, the characters of which are more or less 
fully pointed out: — G. equestris, Retz. (j=S. childy'ejii, M. & Tr.), G. incii. 
Gray — gracilis, Mob.), G. tuherculosus, Mart, (probably distinct from G.
