Natrix rhoinbifera (Hallowellj. — A very large skin in the 

 National ]\Iuseum from Maxey, Dyer County, is identified as 

 this species, probably correctly. The scale rows reach a max- 

 innmi of 2S< ; there are no suboculars ; the pattern is obscure, 

 but seems to be like that of A^. rhomhifera. A more certain 

 record is that furnished by a small specimen collected by 

 Ruthven at Reelfoot Lake.

Matrix sipcdon sipedon ( Linne). — This snake was seen more 

 often than any other. It was found along all the water courses, 

 frequently lying in the bushes or on driftwood ready to drop 

 ofT into the water at the first alarm, and was even common 

 in the village of Henry by some of the numerous small ponds. 

 All the specimens listed below are in the University of Mich- 

 igan Museum and are from Henry, Tennessee. They show 

 no evident approach to A^. fasciata, even though in two speci- 

 mens (53524, 53530) the dorsal saddles are complete through- 

 out the body length, for they all show the half-circular belly 

 spots, diagnostic of sipcdon, and lack the postocular light line 

 ■distinctive of fasciata. 



The species recorded by Rhoades from Samburg was prob- 

 ably this form.
