*12. E. saurita. This well-marked species is comparatively rare. I have seen but three cr 

 four specimens that have been collected within the limits of the State. 



x 17. H. platyrhinos. I have not seen this species, but give it a place in oar fauna on the 

 authority of Prof. A. Sager, the able Zoologist of the former Geological corps, to whom 

 I am indebted for many acts of kindness and encouragement. 



*18. S. vulpinus. The only specimens of this species collected are from the vicinity of Sagi- 

 naw Bay, where it is found in abundance. Although perfectly harmless, it has the 

 unfounded reputation, in that locality, of being venomous and is therefore much 

 dreaded. 



*30. H. triseriatus. I am not acquainted with this species, but give it a place in the cata- 

 logue on the authority of Prof. Baird. 



*38. A. laterale. An immature specimen from Saginaw Bay, I have referred to this species. 



*41. P- ery thronota. This is a common and widely distributed species, being found through- 

 out the State as far north as Lake Superior. 



*43. I have several undetermined specimens of Necturus. seme of which will probably prove 

 to be N. maculatus.
