for the European and Levantine form appears to be E. leprosa, 
Schweigger ; but if E. sigroz^ D. & B., from Spain and N. America, is a 
good species, this will be E. leprosa, and the ’Levantine form must take 
Gray’s name, C. vulgaris. Id. 1. c. pp. 310-312. 
Emys grayiy Dum. & Bocourt, altered to E. umbra. F. Bocourt, 
J. Zool. V. p. 26. 
Emys hamiltoni occurs as far west as Futtehgurh. J. Anderson,

F. Bocourt gives a synoptical table of the species of Cinosternum^ 
which he makes equivalent to Agassiz’s sub-family Cinosternoicles, the 
division into three genera not being based on permanent characters. 
This is followed by. diagnoses of 10 well-established species already 
known, and description of C. rostellum, sp. n., Guanajuato. J. Zool. v. 
pp. 388-399.

OROCODILIA. 
Alligator {Jacare^ punctulatus, var. n. chiaparius. Five specimens 
forming a new variety of this species, obtained by F. Sumichrast in the 
valley of Tonala, Chiapas, establish the existence of alligators in the 
region intermediate between the United States and tropical S. America.

SAURIA. 
The following observations on geographical distribution occur in 
Wallace’s work {supra) ii. pp. 403 & 404 : — The Oriental region is one 
of the poorest both in families and peculiar genera, the Neotropical 
being the richest. Nearctic : 7 families, none peculiar (3 peculiar 
geneva, Chirotes, Ophisaurus, and Phrynosoma). Palaearctic : 12 families,
