[NOTE. The manuscript of this paper was found in Professor Hyatt 'B 

 desk after his death in 1902. In editing it, I have endeavored to alter 

 the original as little as possible, and have been greatly assisted by Dr.

 of these shells enabled him to perceive Professor Hyatt's meaning in 

 instances where the author 's statements were more or less ambiguous or 

 incomplete. A. G. MAYER, Editor.]

 Cooke, Jr., collection of about 7,000 collected with extreme 

 care, and accompanied by a map showing the exact location 

 of each lot of specimens, also generously lent to me. There 

 is also a small collection presented by Dr. C. Montague Cooke, 

 a small but valuable collection presented by Dr. Conrad 

 Wesselhoeft, one from Mr. W. R. Castle, Jr., a small col- 

 lection purchased from D. D. Baldwin containing some im-
