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.
