Posey county, Iu<j. Ho>vever, uo specimens of it were in the collection 

 of Mr, Sampson, of New Harmony. It ought to he diligently sought for 

 in that region, and specimens saved. It is entirely aquatic and will be 

 found hiding among stones, and in fallen timber, or basking in the sun 

 along the banks of ponds and streams. 



This reptile differs from the Copperhead in having no loral plate, no 

 suborbitals, the scales in 25, instead of 23 rows, and colors darker. The 

 ground color is dark chestnut-brown, with blotches of still darker brown. 

 The head is very dark. Upper lip with a whitish streak that continues 

 back on the neck. Belly yellowish, with many blotches of black.

This species is common in the streams and ponds of the Southern 

 States from Georgia to Arizona. It has been reported from Northern 

 Illinois by Messrs. Rice and Davis, and if their determination is correct it 

 adds to the known range of this turtle in a remarkable manner, and as a 

 consequence it is to be looked for in Indiana along the Wabash River. 

 It differs from A. odorata in attaining a larger size, in having a larger 

 head and stronger jaws, and in having a high shell with a median sharp 

 keel toward which the slightly convex sides slope up roof-like. The 

 scutes of the carapace overlap those lying behind them. The plastron is 

 truncated in front and notched behind. The gular scute is wanting. The 

 pectorals are large, and the suture between them is longer than that be- 

 tween the humerals. The males are furnished with two patches of small, 

 sharp-edged scales, one above, the other below, the hollow of the knee. 

 The color of the shell and skin above is olive, with streaks of yellow and 

 spots of brown. The posterior borders of the scutes of the carapace are 

 blackish. All the inferior surfaces are more yellow. There are no 

 streaks of yellow on the head. Habits in general those of its relative, the 

 Musk Turtle. 



Chrysemys picta, (Schneider). 



Painted Tortoise. 



Testudo picta, Schneider, 1783, 87, 348; Eimjs picta, Holbrook, 1842, 

 64-, i, 75, pi. 10 ; Chrysemys picta, Gray, 1855, 25, 32 ; Agassiz, 1857, 

 4, i, 438, pi. i, figs. 1-5, and pi. iii, fig. 4; Boulenger, 1889, 84, 72. 



This species has at various times been reported from localities in this 

 State, and was given as a resident of Indiana in my "Preliminary List."
