APPENDIX. 475 



Occasionally, single gulls are seen inland, or flying over the 

 river not only those mentioned, but other species. 



Tern. Sterna hirundo. 



Occasionally, and particularly after severe easterly storms, terns 

 are quite abundant about the river. They never remain, however, 

 more than two or three days. 



Loon. Colymbus torquatus. 



Not uncommon during autumn and winter, and occasionally 

 seen in summer. 



Red-throated Diver. Colymbus septentrionalis. 



I saw a specimen of this diver that was killed on the river in 

 February, 1879. I carefully examined the specimen a few hours 

 after it was shot. 



Crested Grebe. Podiceps cristatus. 



Every winter, specimens of this bird are killed on the river. 



Devil-Di ver. Podilymb us podiceps. 

 Common. Migratory, but irregularly so. 



REPTILES. 



Land-Turtle, or Box-Tortoise. Cistudo clausa. 

 Muhlenberg's Turtle. Chelopus Muhleribergii. 

 Rough-backed Turtle. Chelopus insculptus. 

 Speckled Turtle. Nanemys guttatus. 



Blanding's Turtle. Emys meleagris. 



The species that I take to be the above is exceedingly rare, and, 

 if not the same, is a nondescript. It does not in every particular 

 agree with the descriptions of the species as given by authors gener- 

 ally. 



Painted Turtle. Chrysemys picta. 

 Red-bellied Turtle. Pseudemys rugosa. 

 Mud-Digger. Cinosternum Pennsylvanicum. 

 Stinking-Turtle. Aromochelys odoratus. 

 Snapper. CJielydra serpentina.
