The Becord of Zoological Literature. 1867. Volume IV. Edited by 
Albert C. L. G. Giintlier, M.A., M.D., F.E.S., &e. London : Van 
Voorst, 1868. — Dr. Glintlier's incomparable work, now in its 
fourth volume, needs no commendation at our bands to ensure 
its support among zoologists. It may be as well, however, to 
point out that the ' Record ' is not exclusively devoted to zoology in 
a taxonomic sense, but includes reference also to the investigations 
of the year in which the microscopist is interested. It extends over 
nearly 700 pages of large 8vo, and includes the titles of the papers 
and books on zoological matters published in the year 1867. In 
addition, it gives brief analyses of all the more important additions 
to knowledge, and in all cases it mentions the source or journal in 
which the paper appeared. When we state further that it deals 
in this way with nearly thirty-seven thousand pages of zoological 
literature, our readers will see how esseutial, necessary, and indis- 
pensable the work is to all who are engaged in original research. 
This volume brings the record up to the end of 1867. The three 
preceding ones dispose of the work in the years 1866, '65, and '64, 
respectively. If the worker wishes to go back farther he must 
consult the appendix to the ' Natural History Eeview ' (a now- 
defunct periodical), which contains a very valuable bibliography 
from about 1860 to 1863 inclusive. If he would go still farther 
back he must consult Carus' ' Bibliotheca.' It is quite impossible 
for any one engaged in biological inquiry to avoid ascertaining 
what has been done already in the field he proposes to cultivate, 
and this work of Dr. Giinther's is intended to meet his wants in 
this direction. 
We shall just give a brief sketch of some of the labours re- 
corded by Dr. Giinther and his colleagues, as this will convey a 
better notion of the work than any mere general statement as to 
its merits. Suppose for the sake of illustration we take the section 
devoted to Protozoa, and inquire what work was done in 1867 
towards increasing our knowledge in this department. Here is a 
store of information collected by Dr. E. Perceval Wright. Let 
us glance only at the record of general treatises, leaving out the 
papers, &c., on species, as too numerous for our purpose. We 
learn that in that year there was one separate publication in this 
group, and that was Herr Stein's ' Der Organismus der Infusions- 
thiere," &c. " This is a folio with sixteen plates. It is the second 
part of Stein's great work on the Infusoria, and gives (1) a 
resume of the result of the latest investigations into the structure, 
mode of increase, and development of the Infusoria, and (2) the 
Natural History of the Heterotrich Infusoria." Next, under the 
head of separate publications, i. e. papers which appeared in 
journals, proceedings of societies, and such like, we find an 
account of nearly thirty memoirs, all devoted to the general con-
