78 Strecker — Reptiles and Batrachians of Texas. 



one of these specimens I dissected I found three adult Haldea striatula. 



Another one contained a small Tropidonotus. 



Ancistrodon piscivorus Lacepede. 



COTTON MOUTH. 



Tolerably common around Waco, but is much more abundant in the 

 post-oak country and at Laguna. Specimens from central Texas are 

 much darker than those from further east, and the hands never display 

 reddish tints. I have never found more than seven embryos in any of 

 the females I have dissected. 



Ancistrodon contortrix Linn. 



COPPERHEAD. 



Tolerably common in the wooded river bottoms, but of late years has 

 become very scarce in the more cultivated districts. 



Sistrurus miliarius Linn. 



GROUND RATTLESNAKE. 



On August 5, 1907, while wo were camped at Mussel Island on the 

 North Bosque River, Gooch found a specimen of this pretty little rattle- 

 snake under an old newspaper lying in the middle of our camp. 



Crotalus atrox Baird and Girard. 



TEXAS RATTLESNAKE. 



The Texas rattlesnake is exceedingly rare. In July, 1905, a large speci- 

 men over six feet in length was killed near China Springs and brought to 

 Waco. 



Crotalus horridus Linn. 



BANDED RATTLESNAKE. 



In my former paper I recorded one specimen of this rattlesnake. Since 

 then I have discovered that it is the prevailing form of Crotalus in this 

 section of central Texas. It is rather common in the post-oak country 

 between "Waco and Laguna. It also occurs near China Springs, and I 

 have had one specimen from McGregor. The specimens I have examined 

 have shown considerable variation in color. In life the ground color of 

 one was light buff, a second, bright yellowish tawny, and a third (now 

 in the Baylor Museum) light salmon. 



Pseudemys texana Baur. 

 TEXAN TURTLE. 



This fine turtle is probably rare, as I have only collected two examples. 

 One of these was caught in the Bosque River, in a seine; the other one 

 was found in a fisherman's net at Laguna. 



Pseudemys elegans Wied. 

 ELEGANT TURTLE. 



Common in most of our streams and rivers; exceedingly abundant at 

 Laguna Lake.
