112 Dr. J. E. Gray on the Tortoises 



waters of Belize, where it is eaten in the early months of the 

 year, and several specimens were received from Mexico. 



They give a very poor figure of the head, from the living 

 animal, which, if correct, has not the black spot on each side 

 of the pupil, so common in American water-tortoises ; and this 

 peculiarity is not noticed in the description. 



In the synonyma the authors refer Emys Berardii of M. 

 A. Dumeril, so badly figured in the Arch, du Museum, 1852, 

 vi. p. 231, t. xv., and Plycliemys (i.e. Ptychemys) Berardii of 

 Agassiz without any doubt as synonyma of this species, which 

 I suppose, settles this question ; but the species was so very 

 badly described that it was a matter of great doubt. 



Emysaurus Rossignonii, Dumeril & Bocourt, I. c. p. 18, 

 t. v. f. 2. 



This species, which is established on three young speci- 

 mens, two from Guatemala and one from Mexico, is distin- 

 guished from the young E. serpentina from Pennsylvania 

 (which they figure t. v. f. 1) by having four beards, two on 

 each side of the symphysis of the chin, a broader sternum, less- 

 marked cuticular processes on the neck and limbs. 



This is a species that has not occurred to me among the 

 many tortoises Mr. Salvin has brought from Guatemala.

Claudius megalocephalus, Bocourt, Ann. Sci. Nat. Zool., 1868, x. p. 122. 



Described from a single specimen in the Paris Museum, 

 received from Mexico. 



This species I have not seen. It is very interesting in the 

 nose not being produced or cylindrical, the chin having two 

 beards, the sternum being acute at each end and covered with 

 four pairs of shields, and the lateral process of the second pec- 

 toral plate being slender. The tail is very short and marked 

 with four longitudinal tubercular ridges.

 I. c. p. 21 ; Gray, Cat. Sh. Rept. t. xx. b. 



The authors add nothing to the account of this animal ; 

 indeed it is doubtful if they have seen it.
