Art. IV. — A Catalogue of the Reptiles of Connecticut, arranged 

 according to their natural families ; prepared for the Yale 

 Natural History Society, by Rev. James H. Linsley, A. M. 



To the Secretary of the Yale Natural History Society : 



Dear Sir — I herewith transmit to the Society a list of the 

 reptiles of Connecticut, as far as ascertained, and as my efforts 

 to make it complete have been extensively exerted, it is believed

1 would take this opportunity to tender my thanks to those 

 gentlemen who have from various towns kindly favored me with 

 specimens, and to those who have informed me of localities of 

 some rare species, to which reference is occasionally made in the 

 notes of this catalogue. My thanks are also especially due to 

 Professor Silliman and Son, for the free access at all times to 

 their valuable libraries, and for the loan of such books as I could 

 not otherwise obtain, not only on this, but every branch of natu-

 is hoped they will not be found altogether uninteresting. 



It was my intention to have accompanied this with catalogues 

 of the fishes and shells of Connecticut, both being nearly ready, 

 but it is desirable to establish some undecided points with re-

 course of this year ; and specimens and communications relating 

 to the discovery of any new species in the zoology of Connec- 

 ticut, will be acceptable. 



Generally in this list, as well as in those which have preceded 

 it, the old names have been preferred, where as it seemed to me 

 no permanent good would be obtained, by the use of modern 

 synonyms. I hope however the article will be not the less in-
