1893. SOME NEW BOOKS. 309 
an adequate systematic zoology, even though he confine himself to 
animals no longer living; the field is far too vast, the literature 
cannot be coped with, and the pity of it all is that young men fresh 
from the examination-room can only be taught their own presumption 
by a fatal experience. 
Despite its inevitable faults, we recommend this book to students 
for the value of its introduction, and for its numerous good illus- 
trations; while, to more advanced workers, it may prove useful as 
setting forth the views of the French school on many subjects, some 
here published for the first time. We will only warn the unsuspecting 
against the specific names at the foot of many of the figures; the 
misprints, which this book shares with others issued by the same 
publishers, they will discover for themselves.

FAUNA UND FLorA DES GOLFES VON NEAPEL: XIX. MONOGRAPHIE; PELAGISCHE 
CopEPoDEN. By Dr. W. Giesbrecht. 4to. Pp. 532, pls. 54. Berlin: Friedlander 
and Sohn, 1892. Subscription price 50 marks. 
THE magnificent series of ‘‘ Naples Monographs,” of which the pre- 
sent is the latest, shows no symptoms of a falling off either in excel- 
lence of matter or in the beauty of illustration and printing. Nor do 
the volumes decrease in size; in fact, they seem to get bulkier with 
increasing age. Those of us who are interested in the work of the 
Marine Biological Association’s Laboratory at Plymouth naturally 
feel some envy at the sight of the nineteen volumes which represent 
the industry of those who are officially connected with the Naples 
Station, or have enjoyed the great facilities for work there offered. 
It is greatly to be regretted that the list of subscribers to the funds of 
the Marine Biological Association is too small to permit of a suff- 
ciently large expenditure of money upon publications. It is rather 
tiresome, too—the writer is naturally expressing his individual opinion 
only—that so much purely utilitarian work has to be done, to the 
partial, but, fortunately, not complete, exclusion of the more interesting 
lines of Biological enquiry, so admirably developed at Naples. 
Dr. Giesbrecht’s work is illustrated by fifty-four double plates, 
of which the first five are devoted to the representation of the living 
Crustacea with all their natural colours. These plates are so splendid 
that we feel ourselves unable to praise them adequately without 
indulging in language of too fulsome a character. The brilliancy of 
colcur often developed in these small creatures is most marvellous ; 
but while some, such as Sapphirina ovato-lanceolata (pl. i., fig. 7), 
exhibit literally all the colours of the rainbow, others are quite plain. 
We wait anxiously to hear authoritatively the reasons for this display 
of adornment. The variety of colour even extends to the eggs; they 
are blue, green, red, olive, or purple—in fact, they are only rivalled in 
variety by the eggs whose use is peculiar to that season of the year 
which has just passed. The remaining plates illustrate chiefly a 
collection of detached appendages of the various species dealt with. 
The development of these appendages is often quite extraordinary, 
while the long plumed hairs which they and the body-surface 
frequently produce are doubtless suggestive of the larval forms of the 
higher Crustacea. The volume is entirely systematic and faunistic 
in scope; the anatomy will be treated of in a second part.
