EMYS. 9 
vermiculations which are darkest on the edges and light in the middle. A short, 
oblique, yellow band behind the eye is very constant. Throat punctulated. The scutes 
are sometimes without markings, sometimes with indistinct yellowish figures. The 
areolar portion of each costal scute is frequently ornamented with a small, oval, yellow 
spot and a narrow annulus. The middle of the sternum blackish. Shell moderately 
depressed, oblong, with the lateral edges not or slightly recurved. Nuchal small, 
occasionally absent. Only a trace of a vertebral keel. Toes not webbed. 
Of this species we have a series of examples from both localities named. The shell 
of the largest example does not exceed § inches inlength. Itis a terrestrial frugivorous 
species. Cope’s description was evidently prior to that of Gray; and Bocourt refers, 
by some error, Cope’s name of “rubidus” to his £. incisus.

This is a South-American species, common in Dutch and British Guiana and other 
tropical parts of South America. However, Cope (J. ¢.) refers to it two Central- 
American specimens, one from Yucatan, and the other from Tabasco. I have not seen 
these specimens, which are preserved in the Smithsonian Institution, and am therefore 
unable to confirm Mr. Cope’s identification. 
Geoclemys callocephalus, or Rhinoclemmys callocephala, Gray, Proc. Zool. Soc. 1863, 
p. 254, is based on a dry specimen, which, after having lived for some time in captivity, 
came into the collection of the British Museum in the year 1853. Its shell is dete- 
riorated ; and of the coloration of the soft parts only so much is preserved as clearly 
shows that the specimen is identical with Emys scabra or punctularia. The figure 
given by Gray of the head of this species is very inaccurate and misleading. 
Nore.—Geoclemmys melanosterna, Gray, Proc. Zool. Soc. 1861, p. 208, is an extra- 
limital species. Of the two specimens known, the type bears its original label “ Chi- 
rambira, Darien,” altered in Gray’s paper to “‘ Cherunha, Gulf of Darien.” Chirambira 
is a place a short distance north of Buenaventura, where the second specimen was 
obtained. Thus there is no doubt that this species belongs to the Colombian 
fauna. 
Geoclemmys annulata, Gray, Proc. Zool. Soc. 1860, p. 231, t. 29, is likewise extra- 
limital, from the coast of Ecuador. Itis true that Gray in the Suppl. Cat. Shield 
Rept. p. 30, and in the Hand-list of Shield Rept. p. 27, refers to Mr. Salvin as the
