resemble those of Testudo radiata. An individual with 

 a carapace measuring four and one-half inches in length by 

 three and one-half in width has less than fourteen lines of 

 growth on each scale. The top and the sides of the head 

 are flecked with small round spots of yellow. In all cases 

 the vertebral keel is obsolete. 



CISTUDO CINOSTERNOIDES Gray ; Garm. 



Dr. Boulenger has examined the type of Gray's Emys 

 kinosternoides, 1831, and, finding it to be identical with 

 Cistudo triunguis of Agassiz, 1857, makes it a variety of 

 C. Carolina. Of one of our specimens the head is yellow- 

 ish green on the top and the sides with a faint yellow spot 

 or two far back on the top and a few larger ones on the 

 sides behind the ears. This one is less than four inches 

 in length of carapace and the scales are smooth, or with 

 traces of striae posteriorly. On the carapace the brown 

 color is dark and the yellow is reduced to scattered small 

 rounded spots ; on the plastron the yellow spots are elon- 

 gate or form short bands, but this color is much less in 

 amount than the brown. Another specimen, with a shell 

 five and a half by four inches, has the head of a chestnut- 

 brown on top and sides, freckled with a few small spots of 

 orange behind the mouth. The carapace is chestnut-brown, 

 darker on the areolss and the posterior borders of the scales 

 on each of which there are faint traces of radiating lines 

 of lighter color. The plastron is yellowish, darker in the 

 sutures. Except in the lack of markings on its head this 

 individual agrees closely with that figured by Wied as G. 

 Carolina, apparently also a three-toed specimen. Each 

 specimen in the collection has the labial scale of orange 

 color with dark edges.
