Prof. Agassiz, in reply to a question from Dr. C. T. Jackson, 

 whether the fishes of the European coast could be transplanted 

 to the shores of America, — said that it was extremely doubtful. 

 From a general point of view he should not suppose that any 

 family of fishes, which have no representatives here, could flourish 

 on this coast ; but that perhaps fish belonging to the same family 

 with the haddock and hake might be naturalized. 



Dr. Chas. Pickering alluded to the geological nature of the 

 European coast, as bearing on the question, that being the only 

 limestone coast with which he was acquainted, with the exception 

 of those of coral regions. 



The Corresponding Secretary read the following let- 

 ters, viz. : — 



From G. C. Swallow, accepting membership ; from the Society 

 E-oyale des Sciences de Liege, Api-il 20, 1856, and June 5, 1857, 

 presenting its Memoirs, and from the same, April 20, 1856, 

 acknowledging the donation of the Society's publications. 



Mr. Charles Stodder presented a specimen of Trilo- 

 bite, {Paradoxides Harlani) from Braintree, which ex- 

 hibited the sculpture of the external integument of the 

 shell upon the under side of the head, and which from 

 its delicacy and extreme thinness is rarely preserved. 

 He remarked that whilst the ornamentation of the integ- 

 ument of the upper surface varies with the genera or 

 species, according to Burmeister, (Organization of Trilo- 

 bites,) that of the under side is the same in all. If this 

 were true, he thought it would prove without a parallel 

 in any other so numerous a class of animals.
