some cases concentrically disposed lines of red corresponding 

 to the yellow lines on the superior surfaces of these plates. 

 Head and neck striped with yellow and orange. A narrow 

 yellow line extends along the middle of the head from the 

 snout to a point just behind the orbit, where it abruptly 

 expands and terminates. Lines on each side extend from 

 the orbit backward upon the sides of the neck, where they 

 become wider and more brightly colored. Of these lines two 

 are more conspicuous than the others; one of them extends 

 from the upper edge of the orbit, where it is very narrow, back- 

 ward and downward, expanding on the posterior part of the 

 iiead and becoming again somewhat narrower upon the neck; 

 the other extends from the middle of the posterior edge of 

 the orbit backward through the upper part of the tympa- 

 num. From the inferior edge of the orbit a stripe extends 

 downward and backward across the angle of the jaws and 

 soon joins another stripe which arises on the middle of the 

 lower jaw; from their point of union a conspicuous stripe con- 

 tinues backward upon the lower part of the neck. A wide 

 stripe extends from the symphysis of the lower jaw backward 

 along the middle line for a short distance, and from it diverge, 

 upon the inferior surface of the neck, two rather wide stripes. 

 A narrow yellow stripe arises at each side of the median tooth 

 of the lower jaw. A line of about the same width extends 

 from the nostril directly downward, for a short distance, and 

 thence obliquely backward to the middle of the side of the 

 upper jaw. Legs and tail striped with orange. Skin anteriorly 

 mottled with black and yellowish lines. Skin of the inguinal 

 region white and immaculate. 



Length of shell, 12.75: depth, 4.75; width, 8.75. 



Apparently not common in the State. Taken only at 

 Mt. Carrael. 



This is a southern species. A fine large example, from 

 which the above description is drawn, was sent me some years 

 ago by Dr. .J. Schneck, to whom the credit of the discovery of the 

 species within our limits belongs. The extralimital distribu- 

 tion of the species includes all the South Atlantic and Gulf 

 States from North Carolina to Texas. It occurs also, according 

 to Prof. Louis Agassiz, in Arkansas and Missouri. The Illinois
