The author remarks that scarcely anything has been published bearing 
upon the development of the teeth of Reptilia and Batrachia since the 
paper in which Huxley, nearly twenty years ago, pointed out that the 
“ papillary stage ” could not be said to exist at any time, either in the 
frog or in certain fish ; he describes the structure and method of forma- 
tion of the teeth, as studied in the above common types.

There is no cementum upon the teeth of Snakes, the tissue so named 
proving to be enamel ; the author believes that the presence of cemen- 
tum in Reptiles generally will be found associated with the implantation 
of the teeth in more or less complete sockets, as in the Crocodiles and 
Ichthyosaurs. 
In “ Anleitung zur wissenschaftlichen Beobachtungen auf Reisen,’^ 
edited by Dr. Neumayer, Berlin, 1875, Dr. Gunther has furnished 
(pp. 389-397) directions as to the methods of conducting original obser- 
vations on Reptiles, and the points to which special attention should be 
given, together with full instructions how to collect and preserve speci- 
mens. 
Dr. SCLATER in his “ Address to the Biological Section of the British 
Association,” 1875, Belfast, makes remarks on the present state of know- 
ledge respecting the geographical distribution of Reptiles.

Europe. 
SCHREIBER, E. Herpetologia Europaea. Braunschweig: 1875, 8vo, 
pp. 639, with numerous woodcuts in the text. 
A compendious account of the Reptilian fauna of Europe, with com- 
plete descriptions of the species and carefully compiled details of habits 
and range. A work greatly needed to assist ordinary observers in identi- 
fying even the commoner forms, as is shown by the number of indepen- 
dent descriptions of species like Zootoca vivipara.
