em parts of the United States, but the fact is otherwise. Dr. C. 

 purchased one in the market, brought from New Hampshire. It is 

 common in the western part of New York State. 



Of the Argus polyplectron, this work asserts that the female has 

 not been described. Dr. C. has one, and will furnish a descrip- 

 tion of it. Tetrao urophasianns is spoken of as abundant on the 

 prairies, and much sought after by hunters. It is so unpalatable 

 that no hunter, unless pressed by famine, would eat it Tetrao 

 umbellus is stated not to be found south of the Gulf of Mexico 

 Nuttall says not south of Georgia. 



Dr. J. B. S. Jackson had recently been afforded an oppor- 

 tunity of examining a specimen of the Tunny or Horse 

 Mackerel. 



According to Dr. Storer, the dorsal fin has 14 rays ; in this spe- 

 cimen there were but nine. 



Dr. Gould remarked that the fin rays of most fishes are exceed- 

 ingly variable, and differ in number even on the two sides of the 

 same fish. 



Dr. Binney confirmed this remark. He also stated that a Tunny 

 had recently been captured off New Brunswick, measuring 16 feet 

 in length. It is not a rare fish, as is usually supposed, but is rarely- 

 taken, because its flesh is not prized for food.
