48 EMYS MUHLENBERGII. 



Dimensions. Length of shell, 3J inches; sternum, 3^ inches; elevation. If 

 inches; tail, H inches. 



Geographical Distribution. Its range is very limited; it being only found in 

 'New Jersey and eastern Pennsylvania, and rarely even in these districts. 



Habits. The Eniys Muhlenbergii lives in small brooks or streams of running 

 water. 



General Remarks. This animal was first described and figured by SchoepfF, 

 in his Historia Testudinum, from specimens furnished him by the Rev. Mr. 

 Muhlenberg of Pennsylvania. Schoepft", however, mistook it for a variety of the 

 Box Tortoise, and gave a drawing of the shell and sternum only. Say next 

 described it in detail, under the name Emys biguttata, from the two remarkable 

 orange spots on the neck; he was probably not aware that Schoepft' had 

 previously given it another name. Leconte has since described this animal with 

 an accuracy that leaves nothing to be desired.
