ECHINODERMATA. 
Benthaster, g. n., for B. wyville-thomsoni and B. penicillatus.

On Oreaster bulbiferus , Forbes, see P. H. Carpenter, Geol. Mag. (2)

OPHIUROIDEA. 
Lyman (31) makes his work a handbook of the Ophiuroidea, which he 
regards as two families of star-fishes — Ophiuridce and Astrophytidce ; 
the former are arranged in three groups. Some anatomical observations 
are scattered through the book, and there are plates devoted to anatomy ; 
it concludes with various useful tables of the general results as to dis- 
tribution, &c. The new species have all been described in earlier pre- 
liminary notices.
