34. Thamnophis proxima Siiy. Oarlcr Siuile. 



One of the most miiuerous of all snakes of Louisiana. 

 OcH'urriug in all parts of the state, but is very partial to the 

 proximity of water. 



35. Thamnophis sirtalis Linn. Garter Sntihr; Striped ISuahe. 

 Nearly as common as T. Pro.vima an<l as equally dis- 



tiibuted. 



3(). Thamnophis sirtalis dorsalis Hd. :\iul Gir. Clnirvhiirs Oarter 

 Slid he. 



During two successive summers I collected this species 

 in the city of New Orleans, I kept them alive on account of 

 their exceedingly handsome markings, and especially distinct 

 red dorsal stripe. Since then [1892 and 1893] I have not 

 succeeded in getting other specimens, the old locality having 

 been built up in recent years. 



37. Thamnophis saurita TJmi. L'ililxm Snake. 

 Notwithstanding this species being knoAvn to belong to 



the Austro-riparian region, 1 have never succeeded in obtain- 

 ing it in the state. 



38. Natrix grahamii Bd. and (^ir. (fraham's Water Snake. 



Very common in the southern section of the state; in the 

 vicinity of New Orleans one of the most abundant of water 

 snakes. I have not found it in northern Louisiana. 



39. Natrix rigida Say. Ilrowii \V((fer Snake. 



Not ({uite as common as the preceding, but liaving about 

 the same range. 1 have foun<l it quite numerous along the 

 shores of Lake (Jata watch i and Lake Sah ador. 

 30 Natrix clarkii lid. and Gir. Clark'.^ Wafer Snake. 



Not common. Strictly confined to the southern section. 

 .31. Natrix fasciata fasciata Lin 11. Banded Water Snake. 



Generally distributed tluougliout the state, and exceed- 

 inglv common everywhere. It is represented by several color 

 varieties, which have been made into sub-si)ecies, but 

 scarcely merit such elevation, since the characteristic differ- 

 eiutes from the type are exceedingly variable andintergradiug- 

 1 have, however, imluded the different varieties in this cata- 

 logue but it is impossible to define any geographical range.
