perhaps, a French name or two — and of thus advancing 
their own personality, and really falsifying the history of 
science. M. de Quatrefages has shown this tendency in his 
‘ Histoire des Annelees/ and it is denounced by M. Clapa- 
rede. We admit, with the critic, that the “ falsification ” is 
probably done unconsciously, or, we should say, carelessly, 
and is rather a national than an individual failing ; and we 
must also observe that M. de Quatrefages has not been able 
to evade the charge in his reply ; nor has he shown why he 
ignored the works of Rathke, Delle Chiaje, Grube, Kolliker, 
Leydig, &c. ; nor again has he given, nor can he give any ex- 
planation of omission in the * Histoire,’ of any account of the 
segmental organs of Polychaeta, many of which M. Claparede 
figures in the present volume. The advisability of constitut- 
ing species of Annelids on ill-preserved museum specimens 
kept in spirits, is a subject which does not admit of much 
discussion, and M. de Quatrefages has very little to say in its 
defence. We objected to this and the absence of figures of 
new species in a notice of the * Histoire * when it appeared. 
The Gulf of Naples is a marvellously prolific source of 
Annelids, for in this volume species of nearly every genus 
occurring on our southern coasts, and a host of others, are 
described and figured. 
One cannot speak too highly of M. Claparede’s figures ; they 
are drawn from life, and even the most highly magnified 
parts of the foot or head are rendered with a softness and 
grace which are to be found in few drawings but those of the 
Swiss professor. The author does not adopt the extensive 
generic subdivisions of Malmgren, nor does he appear to go 
even as far as Kinberg, retaining the genus Polynoe for the 
Lepidonoti, as well as the longer forms. His method of 
studying a species is more like that of Ehlers in his Ilorsten- 
wurme,’ than that of the Scandinavian systematists, accom- 
plished though these latter observers are. Alciopina, a 
minute immature form, parasitic within a Cydippe, is one of 
the most novel forms described by the author. The magni- 
ficent species of Phyllochetopterus and Telepsavus, linking, 
as they obviously do, Chaetopterus to Leucodore, and thence 
to Spio and Nerine, are exceedingly interesting types, and are 
illustrated with great detail. We cannot all at once pick out 
of such a book as this the new or important information it 
contains (additional to that given in the abstract some months 
since), for of nearly every species described something valuable 
is said, and anatomical and histological details of the utmost 
importance are given, witness the figures and accounts of the 
nervous system (differing in much from previous accounts) of
