spaces ill front of these blotches on the vertebral plates and below them 

 on the costal plates are marked by spots and radiating blotches of 

 yellow. The presence of a distinct keel and the absence of a median 

 depression are points readily distinguished. The plastron is yellow, 

 irregularly blotched and mottled with much brown and black, broadest 

 across the feraorals. The upper portion of the head and neck is brown, 

 slightly specked with yellow; a yellow line beginning at the jiosterior of 

 the eye runs back over the ear and the posterior of the skull. Mandible, 

 throat, and lower neck light yellow. UpiDer scales of the legs grayish ; 

 lower scales mostly orange or reddish. The individual described is a 

 female collected at Midway, Ky., by Prof. H. Garman. Another speci- 

 men very similar but younger was sent me by Prof. S. S. Maxwell. This 

 one was collected at the mouth of Billingtons Creek, near Lovelaceville, 

 Ballard County, Ky., in the extreme western portion of the State, where 

 the writer has often observe<l other specimens. Prof. BenJ. B. Pentield, 

 of Nashville, Tenn., sent me two sj)ecimens which agree with the Ken- 

 tucky individuals in every jjoint except that a distinct triangular quad- 

 rato-jugal was present. 



In general form and osteological characters this variety grades into, 

 if it is not identical with, typical specimens of T. Carolina^ and may be 

 regarded as the southern extension of this species. Hence the distri- 

 bution of T. Carolina may be given as eastern United States, south to 

 Carolinas, Georgia, Tennessee, and Kentucky, reaching the Missis- 

 sippi, west to eastern Illinois and Wisconsin, and north to Canada.
