44 FOWLER : 



Agkistrodon contortrix (Linnseus) — Copperhead. 



Reported from near Haverford about 1913 by Mr. E. R. Dunn. 



Sceloponis undulatus (Latreille) — Pine-tree Lizard. 



Known from Cope's records,* given as Delaware County 

 and Upper Darby. No recent material has been obtained. It 

 is apparently rare. 



Chelydra serpetitina (Linnaeus) — Snapping Turtle. 



Abundant in some sections. Found at Wawa, headwaters of 

 Ridley Creek and on Tinicum Island. 



SternothcErus odoratus (Latreille) — Musk Turtle. 



Though likely abundant along the more sluggish streams, 

 but few examples have come to notice. Wawa and Lester. 



Chrysemys picta (Schneider) — Painted Terrapin. 



The most abundant of our aquatic species. I found it at 

 Wawa, Lester and Chad's Ford. 



Clemmys guttata (Schneider) — Spotted Terrapin. 



A common species, and usually found in similar situations 

 as the preceding. Wawa, Markham, Chad's Ford, Lester, 

 Collingdale. 



Clemmys muhlenbergii (Schoepff) — Muhlenberg's Terrapin. 



This is less frequent than most of our terrapins, and usually 

 occurs about swamps and ditches. First recorded by Bou- 

 langerf from Upper Darby. Subsequently Dr. Stonet obtained 

 it from Tinicum. I found it at Media, and it was reported 

 from Lester and Lazaretto.
