 and is not unfrequently found in cranberry (Oxycoccus macrocarpus) marshes.

General Remarks. To Dr. Kirtland of Ohio, a distinguished naturalist, well 

 known by his writings on Conchology and Ichthyology, am I indebted for a 

 knowledge of this new and beautiful reptile, and to him have I dedicated the 

 species. In his Zoological Report of Ohio, he observes that this animal is 

 commonly known under the name Massasaugua, a word of Indian origin. He 

 furthermore informs me by letter, that he observed it many years since: thus he 

 says, "In the year 1810, I spent a summer in Trumbull county, (Ohio,) and while 

 there, engaged in boyish pursuits around a cranberry marsh in Boardman, I 

 frequently met with them. A recollection of their appearance at that day 

 contrasted with your plate of the Crotalus miliarius, induced me to examine a 

 specimen three years since, which ultimately led me to conclude that it was a 

 distinct species. Its bite, I believe, is never fatal, and, so far as I have had 

 experience, is not much more venomous than the sting of a common hornet, 

 (Vespa maculata.) In one instance, however, its bite was followed by a long 

 train of nervous and hysterical affections in a female."
