ceedings. Mr. Henshaw found insects abundant at Anticosti, and 

 other localities, and brought home about five thousand specimens. 

 He also collected and preserved fresh-water animals and plants. 



Mr. Kerr collected many valuable fossils which were given 

 to the Society. Mr. Gardiner acted as navigator and also per- 

 formed other onerous duties, really acting as Assistant in charge 

 of the yacht. To all of these gentlemen the Society owes its 

 thanks for their voluntary contributions, since the expedition was 

 made at no cost to the Society beyond the ordinary appropria- 

 tions for summer work, and the collecting materials, alcohol, etc. 

 Mr. Warren assisted Mr. Brewster in preparing his birds. The 

 most valuable of the accessions is a fine and extensive series of 

 specimens of the extraordinary fossil genus, Beatricea. This 

 material will probably enable us to settle the true nature of this 

 fossil, which has been at different times successively described as* 

 a plant, a coral, a cephalopod, and lately as a sponge. 



In the summer of 1861, Prof. N. S. Shaler, Prof. A. E. Verrill, 

 and the Curator, all three at that time students of Prof. Louis 

 Agassiz, went over the same track, but spent more time at Anti- 

 costi, making large collections now stored in the Mus. Comp. Zool. 

 at Cambridge. We found no specimens of the Unionidae in the 

 fresh-water at that island, but this time we found Margaritana 

 (Alasmodonta) arcuata living in Fox River. 



The weather in the Gulf was exceptionally bad, even for that 

 stormy region. The log book shows that there were but eighteen 

 moderately fair days, some of these more or less interrupted by 

 showers, during the sixty-two occupied in the trip. The ordinary 

 temperature in the cabin was about 58° Fahr., rising rarely above 

 60°, and falling once to 37° and once to 34° Fahr. We did not 

 attempt dredging since this would only have been successfully 

 done by the sacrifice of opportunities for shore collecting of much 

 greater value for the purposes of the expedition.
