The enormous list of literary references given by Meissner under the heading 

 of ^Hemiaster cavernosus^ in the two papers quoted is for the greatest part erro- 

 neous, as seen by the list given above. As certain references can only be given 

 those named here. (A few citations, where alone the names are given, have been 

 omitted.) Perhaps there may be some true A. cavernosus among the »Chailenger»- 

 specimens, but most of them, at least, are A. cordatus; those from Stat. 310 (p. 184) 

 are partly A. Philippii. — Among the specimens mentioned from Chili by MEISS- 

 NER there is at least one Tripylus excavatus (sent to me for examination). That 

 De Loriol's Hemiaster gallegosensis is synonymous with A. cavernosus cannot be 

 doubted; but De Loriol can in no way be blamed for having established it as a 

 separate species. He has trusted that the species described by A. AGASSIZ as H. ca- 

 vernosus was really identical with Philippi's species; it is, however, not so, the H. 

 cavernosus (and australis) of the ^Revision of Echini», being A. Agassizii, while that 

 mentioned in the ^Challenger* Echinoidea is A. cordatus. But De Loriol was quite 

 right that his specimens represented another species.
