Dr. J. E. Gray on American Emydidse. 183 



E. scabra, No. 2, Gray, Cat. /. c. 78. Testudo punctulai'ia, 

 Daudin ? 



With a spot on each side of the nose, and a band on each 

 side of the crown, from the forehead, across the orbit, to the 

 edge of the temple, and a spot on each side of the occiput. 

 The underside of the margin of the young shell variegated. 

 Throat black, streaked on the sides. 



Hab. East coast of tropical America. Guiana; Brit. Mus. 



I only know this species in the young state ; but they all 

 have the band on the side of the face interrupted by the orbit. 



2. Rhinoclemys Bellii. Testudo scabra, Bell, Test. t. 1, 2 (adult). 



Head with a spot on each side of the nose and of the occiput, 

 and with a sinuous urn-shaped band on the crown, over the orbit 

 and temples. 



Hab. Tropical America. 



The figure differs from any species we have by the super- 

 ciliary bands being united by a short transverse band in front 

 between the eyes. 



3. Rhinoclemys melanosterna, Geoclemmys melanosterna, Gray, 

 Proc. Zooi. Soc. 1861, p. 205. Emys scabra, No. 1, Gray, 

 Cat. /. c. p. 78. E. dorsalis, Gray, Cat. l. c. 32, t. 14 a (not 

 Spix). 



The side of the head with a continued band on each side, 

 from the nose to the temple. Neck with four broad black 

 streaks on the sides ; fore legs pale, with some black stripes. 



One of the bands on the neck arises from the streak on the 

 face under the eyes, and the upper one from the dark upper 

 margin of the streak on the sides of the head. 



Hab. East coast of Tropical America. New Granada, River 

 Buonventura; J. 0. Goodridge, Esq. Gulf of Darien. 



Emys dorsalis of Spix, Bras. T. II. t. 9. f. 1, 2, which is de- 

 scribed and figured from a young specimen, seems to be different 

 from those here described. 



One species has the dorsal keel pale, and the head and neck 

 with several pale bands or streaks. The toes are short, conical, 

 without any web ; the second and third hinder toes are the least, 

 and nearly equal. I propose to call this gi-oup Callopsis. 



4. Rhinoclemys annulata. Geoclemmys annulata, Gray, Proc. 

 Zool. Soc. 1860, 231, t. 



Hab. West coast of America. Esmaraldas, in Ecuador ; Frazer. 

 Gulf of Darien ; Salvin.
