In the first part of this memoir Prof. Sars describes a remark- 
able new genus of Lily-star, the description of which will be 
found in the special part of this liecord. In the second part he 
gives some details as to the development of Antedon sarsiiy 
contrasting it with that of Antedon rosaceus previously investi- 
gated by Prof. Wyville Thomson.

Leipzig, 1868. 
These are the last parts of this valuable monograph of the 
Philippine Holothuroids. The annotated list of all the known 
species, the chapters on the anatomy of the class, and on 
the geographical distribution of the species, given in this 
volume, render this work almost a monograph. About 272 
species are fairly established. In Selenka^s list, even allowing 
for synonyms, there were but 212. The wonderful genus 
Rhopalodina, Gray, type of a new subclass of Echinodermata, 
is figured, and its anatomy given, in a supplement. Zoologists 
trust that the rest of the Echinoderms of the Philippine Islands 
may soon be monographed in like manner by Dr. Semper. 
The plates (of which the coloured ones are by Madame Semper) 
are very beautiful, and of great scientific accuracy.
