Dr. J. B. S. Jackson stated that, when recently at Nan- 

 tucket, he had examined, as well as he could, on the spot, 

 the anatomy of several specimens of swell-fish, Tetraodon 

 turgidus, and he had reason to suppose, contrary to the 

 opinion of others, that the part of the animal which is in- 

 flated, is truly the stomach. The observations, however, 

 were made under unfavorable circumstances, and the result 

 being unexpected, he desired not to commit himself as to 

 this opinion, until he could have an opportunity of a more 

 careful investigation.

Dr. D. H. Storer mentioned that he had received a letter 

 from Prof. J. P. Kirtland, of Cleveland, Ohio, dated July 17, 

 1845, mentioning some facts which might be interesting to 

 ornithologists. At the date of the letter, flocks of the pine- 

 finch, Fringilla pinea, were flying about his garden, and 

 also the Bohemian wax-wing, Bomhycilla garrula, thirty 

 or forty specimens of which had been taken. 



Dr. Storer read a letter from Dr. Richard Parnell, author 

 of a prize essay on the fishes of the Frith of Forth, an- 

 nouncing that he was giving his attention to the fishes of 

 the West Indies.
