40 THE ZOOLOGIST. 
Sarcodictyon (Rhizoxenia fide Norman), catenata Forbes (= 8S. 
agglomeratum, ¥.), and S. albicolor, Norm. (possibly a variety of 
the former); also Kophobelemnon miilleri, Sars., and Bathyptilwm 
carpenteri, Koll. ; and several others. 
Although the Lucernarie are, strictly speaking, Meduse, their 
habit is ‘‘zoophytic,” and they might very well have been 
inserted, especially as the Rey. Dr. Landsborough described them 
in the prototype of this book. The only Medusa mentioned is 
the exotic fresh-water Medusa (Limnocodium sowerbii, Allm.), and 
this is inserted at the end of the Polyzoa. 
The localities of several of the rarer species have not been 
recorded which have been added by Prof. Herdman from Lamlash 
Bay, by Drs. Leslie and Herdman from the Firth of Forth, and by 
other naturalists from various parts of the British coast. The 
following new species are imperfectly described and figured :— 
Tubularia Britannica, Sertularia argentella, and Aglaophenia 
plumosa. 
In order that such a work as this should enable a beginner 
to identify any form he comes across, either of the two following 
conditions is absolutely necessary—(1) an accurate figure of a 
characteristic species of at least every genus, or (2) tables or 
analyses by which any genus or species may be ascertained. 
Neither of these is found in this book, and it is difficult to under- 
stand how anyone not previously acquainted with many of the 
species could hope to name his captures, especially since all the 
species are not described, even when mentioned; for example, 
Edwardsia allmani, M‘Int., and EF. goodsiri, M‘Int., are merely 
referred to; unfortunately also they are placed under the genus 
Edwardsiella, although they possess less than twenty tentacles. 
(These forms will probably prove to be varieties of H. beau- 
tempsit, Quatr.). The bibliography has throughout the book been 
compiled in a perfunctory manner. 
Nevertheless to the naturalist who already has some ac- 
quaintance with the forms described, and who requires a handy 
book of reference in the laboratory or at the sea-side, this work 
will prove very useful.
