present species, however, belongs to a different genus, and is allied to 
Camponotus.

NOTICES OF NEW BOOKS. 
A History of the British Marine Polyzoa. By the Rev. THomas 
Hincxs, B.A., F.R.S. 2 vols., 8vo. J. Van Voorst. 1880. 
Tus volume, which has been expected for some time, will 
be welcomed by those interested in the study of this group, and 
workers will now find their labours much lessened, for the literature 
on the British Bryozoa, being widely scattered in various 
periodicals, has made the study very laborious. The book which 
up to the present time has been used in the determination of 
species has been Busk’s British Museum catalogue, but since 
this was published, many new species have been discovered in the 
British seas, and several important works on recent forms from 
European and American waters have appeared; besides which 
great advances in the physiology and embryology have been made 
by Smitt, Nitsch, Joliet, aud Barrois, and therefore a first 
class manual like the one before us should attract many workers, 
where it will be seen there is still much to be done. 
The introduction of one hundred and thirty-five pages gives 
au elaborate and full account of the structure and physiology, and 
is thoroughly scientific in giving the results obtained by others 
with great fairness. Those who have seen Mr. Hincks’s 
previous papers will not be surprised to find so good a worker 
boldly acknowledging a change of opinion when that which 
he previously advocated has, upon wider study, proved incorrect 
(as is the case with the so-called “‘ colonial nervous system” or 
endosare) ; and again, the account of the so-called ‘‘ brown bodies” 
fairly represents the changes that have taken place since he first 
took part in the discussion respecting them. 
The Bryozoa, with the exception of Loxosoma, occur as 
colonies, in which each Bryozoon consists of the zocecium or
