and sayi of the west are so constant as to deserve trinomial recog- 

 nition. 



Specimen: Samburg, 1 ad. 



Genus HETERODON Beauvais, Latreille. 



23. Heterodon platyrhinus Latr. Hog-nosed Snake. 



Of the three Samburg specimens one adult is noteworthy in hav- 

 ing the body and tail a uniform grayish olive above and ashy 

 white below, without markings. The head and neck have the nor- 

 mal black markings. 



Specimens: Samburg, 2 ad. , 1 juv. 



Genus CARPHOPHIS Gervais. D'Orbigny. 



24. Carphophis amoenus (Say). Ground Snake. 



In the Raleigh specimen there are no internasal scutes. In one 

 from Sawyer's Springs the right internasal is partly developed 

 and in the other both internasals are present. 



Specimens: Raleigh, 1 ad.; Sawyer's Springs, 2 ad. 



Family CROTALID^ffi. 

 Genus CROTALUS Linnaeus. 



25. Crotalus horridus L. Timber Rattlesnake. 



I did not actually meet with this snake, but secured the rattle 

 of a specimen killed near Samburg during my stay. They are nu- 

 merous in West Tennesseee. 



Genus AGKISTRODON Beauvais. 



26. Agkistrodon contortrix (L. ). Copperhead. 



This snake is abundant in the western half of the State. Two 

 specimens were caught in the runways of mice in the small 

 "Cyclone" traps which were used for trapping mammals. This 

 would indicate that small rodents are a favorite food of the Cop- 

 perhead and are systematically pursued in their burrows. 



Specimens: Samburg, 2 ad.; Raleigh, 1 ad.; Sawyer's Springs, 

 1 juv. 



27. Agkistrodon piscivorus (Lacep.). Water Moccasin. 



Though the Moccasin is accounted abundant by the people of 

 Reelfoot Lake, I did not secure or positively recognize more than 

 one specimen. 



Specimen : 1, half-grown.
