In the course of the next ten days, a complete printed list of all 

 the members of the Association, together Avith their exact addresses, 

 memorandum of subjects chosen for special study etc. will be issued, 

 and a copy sent to each member for his own use. 



We are please to note the enrollment of two such distinguished 

 Conchological veterans as Dr. Xewcomb and Wm. G. Binney. Mr. 

 Binney writes that " it will be a pleasure to me to assist all who are 

 studying mollusks, but I fear indifferent health will prevent my being 

 of much use to them." Dr. Newcomb writes in the same kind spirit, 

 desiring to aid younger students in their work. 



Dr. Newcomb is now 82 years of age — probably the oldest living 

 American Conchologist. He has been a great worker, having 

 collected upon 23 of the West India Islands, in the interior of 

 British Guiana, in Equador and Colombia, Nicaragua, Costa Rica, 

 Honduras, and West Mexico to Panama, in California and on 6 of 

 the Sandwich Island group. His publications are numerous, 

 many papers by him having appeared in the Conchological 

 journals of Europe and America. As he himself Avrites " I am al- 

 most alone; my old friends Agassiz, Gould, the elder Binney, 

 Anthony, Lea, Reeve, Cuming, Swift, Bland, Wheatley and many 

 others have passed away." 



O. A. Crandall, Sedalia, Mo. is studying the genus Physa and 

 writes as follows. " If the members of the Association will send me 

 specimens of Physa from all over the country, I will take it as a 

 favor, besides returning them value in other exchanges."

 that in the last Nautilus, Mr. Carpenter speaks doubtfully of pearls
