Professor Hyatt showed a cast of a femur of Atlantosaurus, a 

 gigantic Jurassic Dinosaur perhaps eighty feet long, presented by 

 Professor O. C. Marsh to the Museum. The thanks of the Society 

 were unanimously voted to Professor Marsh for this valuable gift. 



Section of Entomology, Nov. 24, 1886. 



The President, Mr. S. H. Scudder, in the chair. 



Mr. J. H. Emerton showed the nest of Atypus Riversi of Cali- 

 fornia, which has a tubular entrance projecting an inch or two 

 above the ground. He also showed a collection of the family 

 Cinifloniclae, with drawings of some of the species to illustrate a 

 monograph of the group soon to be published, and described the 

 characteristics of the principal forms. 



Mr. S. H. Scudder spoke of the conflicting evidence regarding the 

 introduction of Pieris rapae. It probably first appeared in Quebec 

 in 1860 and spread into New England in 1865, working to the 

 southern part in four or five years. 



Miss C. H. Clarke showed specimens of Ptinus fur, which had 

 been living in a box of red pepper over a year. 



General Meeting, Dec. 1, 1886. 



The President, Mr. S. H. Scudder, in the chair. 



The President announced the death of Capt. N. E. Atwood of 

 Provincetown, a corresponding member since 1847. Mr. F. TV". 

 Putnam was to have given some account of Captain Atwood, but 

 being unable to be present has since sent the following notice. 



" Those among us who remember Captain Atwood a quarter of 

 a century or more ago, when he so often spoke to us from the vast 

 store of facts which he had gathered during his life as a fisherman 

 and sailor, will always remember our dear old friend and his kindly 

 ways. Whenever he was seen to enter our meeting-room we were 

 sure that there would be no dearth of material for an instructive 

 evening. Often he would come prepared to speak about the habits 

 of some fish well known to us by name and taste, or perhaps 

 about the lobster and the changes he had observed in that fishery,
