Votume I, of this Monograph, published in 1920, dealt with Nueras, 
Lacerta, and Algiroides; Volume II. deals with the remaining 
nineteen genera—Philochortus to Holaspis. Appended is a complete 
Catalogue of the specimens in the British Museum Collection, com- 
prising over 5000, referable to about 200 species and varieties. In 
the tabulations of dimensions and scale-formule which are given 
throughout the work numbers of other specimens are also included, 
each marked with a symbol denoting the museum in which it is to 
be found ; so that in future the student will be able to find any one 
individual for reference from among this vast material. In this it 
is an infinitely more comprehensive work than anything of its kind 
hitherto published, and its value can hardly be overrated. The 
general arrangement is clear and convenient. From the systematic 
and philosophic standpoints it constitutes a magnificent piece of 
work, for it gives one a sound orientation of this difficult group of 
lizards, so baffling to the novice. So many authors present their 
subject to the reader in a biassed form, suppressing evidence or hypo- 
theses which do not corroborate their own views. Dr. Boulenger 
never misleads in this way. Moot points are brought forward as 
such and fully discussed. In dealing with the diphyletie origin of 
Scaptira, for instance, the natural relationships of the Asiatic and 
South African species are clearly expressed, and his reasons for 
maintaining them as distinct genera given; at the same time he 
discusses the principle involved, and adds :—‘ If, however, objection 
should be felt to the course here followed, I would suggest uniting 
the two genera into one, keeping up the different sections as here 
defined, rather than afurther multiplication of the genera” (p. 348). 
Herpetologists all over the world will sincerely regret that the 
* Monograph of the Lacertide ’ is probably the final work on Zoology 
from the pen of Dr. Boulenger. In all he has published 29 com- 
plete volumes and 875 papers ; there is, however, still much to be 
done, and no one will fill the gap which he has left by his retirement.

Tis book, as the Author states in the Preface, is very largely a 
compilation, and this must necessarily be the case in a work dealing 
with such a variety of subjects. In Part I., the “ Animal World,”
