146 BULLETIN OF THE 



addition fo the land animals described in Professor Emmons's Massa- 

 chusetts report, while two of Emmons's Cervida: and the Wolverine are 

 very properly omitted. 



Dr. De Kay's Report, which appeared but a few months later than 

 Linsley's Catalogue, gives seventy-eight species as either actual or 

 former inhabitants of the State of New York, including, in addition to 

 the domestic and marine species of Linsley's list, five fossil species. 

 No new ones are added, though several arc described as such, and 

 several previously well known are separated from their supposed dis- 

 tinct European allies and receive new names. Two species given by 

 Linsley for Connecticut ( u Arvicola floridanus Ord " and " Phoca 

 grcenlandica ? Mull.") are rightly omitted, and others, including the 

 Opossum (Didelphys virginiana), added. This is a southern species 

 which has not yet, so far as I can learn, been detected east of the Hud- 

 son. Deducting the nominal species and those of doubtful reference, 

 nine in number, and the eight domestic and five fossil, leaves fifty-six 

 as the number of living valid ones, forty-six being land and ten marine. 

 This is an excess of four only, — two bats and two very small 

 species of shrew, — excluding the marine and the extra-limital Didel- 

 phys virginiana, over the number given by Dr. Emmons for Massa- 

 chusetts. 



Professor Thompson's Natural History of Vermont, published at 

 about the same time, contains forty-three valid species, with descrip- 

 tions of them drawn up mainly from Vermont specimens, and short 

 general accounts of their habits. It embraces but one or two species 

 not given in Dr. Emmons's report, one of which is the common Seal 

 (Phoca vitulina). A single specimen of this is reported to have been 

 captured on the ice in Lake Champlain, and in the Appendix, pub- 

 lished in 1853, another similar instance is recorded. 



The present catalogue embraces sixty-five species, giving for the first 

 time a probably nearly complete list of the marine, the Seals and 

 Cetaceans. The latter are now supposed to number eighteen species. 

 Four land species (Scotophilia georgianus, Scahps Breweri, Neosorex 

 palustris, and Arvicola pinetorum) are also added, that are not men- 

 tioned by either Dr. Emmons or Mr. Samuels, or by either of the extra- 

 limital authors mentioned above. 



In Massachusetts, as far as Mammals and Birds are concerned, por- 

 tions of two Fauna? are represented, — the Canadian and the Alleghanian ;
