Agassiz (J. c.) mentions that he had received specimens of this species from Pensacola, 
‘Texas, and from Nuevo Leon, near Cadereita, Mexico. I have not seen an example of 
the species, unless the type of Emys ventricosa, the origin of which is unknown, belongs 
to it.

Hab. West coast of CenTRAL AMERICA. 
This, perhaps the most beautiful, species of this section of Hmys, has been well 
figured by Gray, so that a further description seems to be unnecessary. Only the 
typical specimen is known, and there is every reason to believe that it came into the 
collection of Haslar Hospital with a number of other objects from the west coast of 
Central America; at any rate, it will be well to include it provisionally in the present 
list, as it has been confounded with the following species.

This species differs from all the preceding species by the acutely-pointed snout, 
which is conspicuously longer than the eye. The hind feet, as well as the fore feet, are 
broadly webbed ; the claws sharp and long. The shell is much depressed, slightly 
rugose or smooth, and generally very similar to that of Hmys ornata. The type of the 
coloration of the soft parts also very much resembles that of the latter species, but the 
* The author of the Record on Reptiles for 1876 refers to p. 26 of the ‘Journal de Zoologie.’ This is 
incorrect ; he merely used a separate copy of M. Bocourt’s paper, which cannot legitimately be considered a 
publication, and at the end of which a note is added in which the change of name from grayt to umbra is 
proposed, As this note does not occur in the really published paper in the ‘Journal de Zoologie,’ 1876, p. 411, 
+he publication of the name wmbra rests solely with the notice in the ‘ Zoological Record’ as quoted above.
