Reclamation of Salamander*. 



found associated with the S. erythronota, and though very differ- 

 ent from it in colour, I am disposed to think it merely a variety of 

 that species. Their favorite places of retreat are under large 

 stones, and not under prostrated logs or fallen trees, as is common 

 with the other land species. The S. Tigrina is perhaps the finest 

 of our species, and serves to form a natural link in a chain of re- 

 semblances, between the S. subviolacea and the S. fasciata. These 

 three animals, together with the S. glutinosa and S. variolata, 

 form a group which is exceedingly analogous in many particulars. 

 I have no doubt of the correctness of your remark, that the 8. 

 punctata of Gmelin is the same with the S. symmetrica. This last 

 is not so numerous as many of the other species, but it inhabits 

 our country from Florida to Maine. 



Our well characterized aquatic species, are 



Salamandra Longicauda. Green. 



Subfusca. Green. 



Bislineata. Green. 



JefTersoniana. Green. 



The S. Rubra of Daudin, which appears to have been the first 

 of these animals described, comes very near to my S. Rubriventris. 

 Var. Whether the S. maculata be a distinct species, is yet doubt- 

 ful. These three, in certain stages of growth, and especially 

 when preserved in alcohol, require minute attention to distinguish 

 from each other. The S. porphyritica, in some of its characters, 

 approaches to S. JefTersoniana, but it is distinct. 



Were I not fearful of becoming tedious, I could add many oth- 

 er particulars on this subject. I shall therefore reserve them for 

 my contemplated monograph. The error which I have noticed in 

 your late invaluable work, I hope you will correct, by the publi- 

 cation of a portion of this letter, or in any other way which your 

 better judgment may dictate. Were it not that your book is des- 

 tined for remote posterity, I should not be at all solicitous on a 

 subject which is in itself so unimportant. 



With sentiments of gratitude and respect, 

 1 am yours truly, 



JACOB GREEN. 

 P. S. I shall publish a portion of this letter in some scientific 

 periodical in this country.
