often molested, and usually show entire fearlessness of the near- 

 ness of man. 



Remains of some cetacean (not a whale), about seventeen feet 

 long, were cast upon the beach during a storm in October last, 

 but identification was impossible, owing to the advanced stage of 

 decay. 



Lasiurus cinereus, Allen. 



Occasional specimens, in summer. 



L, noveboracensis, Gray. 



Very abundant in summer, and appearing to live mostly in and 

 about the fort itself, as far as the eastern extremity of the island 

 is concerned ; other suitable hiding-places not being in plenty. 



Scalops aquaticus, Fischer. 



Occasional traces of this animal's presence in the loose soil 

 betweeu the sand-hills and the marsh. 



Sciurus carolinensis, Gmelin. 



Very abundant in all the wooded vicinity. 



Mus decumanus, Pallas. 

 M. inusculus, Linn. 



Ever^'where about the fort and other settlements. 



Fiber zibethicus, Cuvier. 

 Common. 



Lepus sylvaticus, Bach. 



One specimen from the neighboring island of Shackleford — the 

 only one I ever saw in the vicinity. I scarcely think that it 

 occurs on Borden, where the next species abounds. 



L. palustris, Bach. 



The most abundant and characteristic mammal of the island. 



I gave some account of this species, in the Proceedings of the 

 Boston Natural History Society for 1869 (p. 89), and have little 

 to add to what there appears, or may be gathered from Audubon's 

 and Bachman's article. 



The animal sometimes reproduces in April, more commonl}'^ in 

 May, and thence during part of the summer ; I do not know 

 whether more than one litter is reared, but think such is the case. 

 The nest is a snug, pretty affair, in a tussock of rank grass or
