This work is extracted from the * Memoires de la Societe de 
Physique de Geneve,^ tomes xix. & xx., with the addition of a 
plate (pi. 32), which is reprinted from the Transactions of the 
Society Italiana di Scienze Naturali. 
Two hundred and twenty-one species of Chetopod Annelids 
are enumerated as inhabiting the Gulf of Naples, Diagnoses, 
accompanied by elaborate anatomical details, are given of each 
species. It is needless to say more of this work, or of its illus- 
trations, than that it is quite indispensable to every worker 
on this special group, and that it is worthy of its author. In the 
special part we give a list of the new genera and species, and we 
now and then call attention to a few of the more remarkable 
anatomical and physiological novelties alluded to by the author.

The concluding portion of the first volume of this work treats 
of the Eunicea, Lycoridea, Nephthydea, and Glycerea. Several 
new genera and species are described, and a list of known species 
is appended to each genus. 
The want of an alphabetical index of genera and species to 
this volume will be very much felt by students; a two-page 
table of contents to a quarto volume of upwards of seven hun- 
dred pages is surely not sufficient.
