Gervais, P. Gas de polymelie (merahres surnumeraires) ob- 
serves sur un Batracien du genre Pelohates, et sur line 
espece du genre Rate. ' Compt. rend. Acad. Sc, Paris, 1864, 
ii. November 14 (pp. 800-803). 
Polymely is that kind of monstrosity in which some part of one 
or more extremities is doubled. 
Only three cases were known among Batrachians ; in the case 
observed by M. Gervais, the left fore foot of a Pelobates cultripes 
is double. These cases are of some interest, as they occur in 
Vertebrates the larvje of which are destitute of extremities, and 
therefore prove the incorrectness of the opinion that these mon- 
sters are the result of a fusion of two originally separate foetuses. 
The other case, observed in a Ray, will be mentioned below.

A statement made by Van der Iloeven (Philos. Zool. p. 330), 
that the number of species of Reptiles known is 1500, de])cnds 
on antiquated data, and is much too lowi

The British Museum has received from Dr. Bleeker the col- 
lection of typical specimens of the species of Reptiles named or 
described by him in the ^ Natuurkundig Tydschrift for Neder- 
landsch Indie.^ Dr. Gray (Proc. Zool. Soc. 1864, p. 11) has 
examined the tortoises, and refers the specimens to species pre- 
viously known.

Dermalcmys mawii (Bibr.). Dr. Gray (Proc. Zool. Soc. 1804, p. 125) lias 
examined an entire animal, which he describes ; he repeats a statement made 
in his ‘ Shield Reptiles,’ p. 60, viz. that A. Dumeril’s Emys herrardi is identical 
with it, and that the figure given by that gentleman is inaccurate.
