Our No. l)()")!>a^ has two extra trian;;ular plates one on cadi side, 

 betwoen tlio tii-st vcrtcbrals aiul lirst coslals. 



The spots of yellow on this spocies are subject to quite a varied 

 arranjjoinent. In many cases the arran^'enient is irrej^'uhir. Tliere 

 seems to he a tendency for each marj;inal phite to have one yellow 

 spot, each vertebral plate one and each costal plate two, one outside 

 and in fmnt of the lary;er one. With this ^^oes one or two pairs of 

 round yellow spots on the head between the eyes, and a pair of 

 elongated yellow spots further back. One of our specinaens has a 

 single yellow spot between the eyes. 



This species is found in the Eastern United States, westward to 

 Indiana; it is also common in southwestern Ontario and is found as 

 far south as North ('aroliua. In our own ^tate it appears to be 

 decidedly eastern and southern in distribution, as most specimens 

 which we have received are from the Eastern and Southeastern 

 portions of Pennsylvania. 



"Frequents sluggish streams, ponds and ditches with muddy bot- 

 tom, but 1 have not seen them where the water itself was muddy. 

 Observed with picta in N. Y., in about equal numbers. Strictly 

 aquatic. Frequently observed on edges of ponds and on logs, from 

 which they plunge quickly when approached. Bury in mud in the 

 fall to winter over." — Smith, p. Gfil. 



"Less exclusively aquatic than most si>ecies of turtles. It seems 

 to delight in being in the neighborhood of swamps and sluggish 

 streams, and it pii)bably spends the greater part of its time in the 

 water. Nevertheless it often leaves the water. It is very harmless 

 and deserves protection. When at freedom they collect in numbers 

 on objects above the water and enjoy the sunshine; but if any fancied 

 enemy is seen approaching they slide off rapidly into the water and 

 soon bury themselves in the mud.'' — Hay, 577. 



"S. E. Pennsylvania and S. N. J., even in pine barrens, but pro- 

 bably not in the higher mountains." — Stone, p. 170.
