A collection from the Triassic of Connecticut was purchased of 

 Mr. S. Ward Loper. This collection embraces fishes, plants, and 

 certain geological features of the formation, as rain-drop impres- 

 sions, ripple marks, etc. A box of Eocene fossiliferous sand from 

 Claiborne, Alabama, was received from Professor P. H. Mell. This 

 material was sorted and determined by Mr. Vaughan. The rich- 

 ness of the sand is attested by the fact that a half-bushel of it 

 yielded one hundred and sixty species, mostly Mollusca. Repre- 

 sentative Tertiary and some Cretaceous material from the Atlantic 

 coast was received from Professor Win, B. Clark of Johns Hopkins. 

 As in previous years, thanks are due to Professor C. B. Beecher 

 of Yale for material received from him. Cretaceous and Ter- 

 tiary material from the West, and Carboniferous from Joggins, 

 Nova Scotia, was purchased of Mr. George B. Frazar. 



Especial mention should be made of the gift of two geological 

 maps to the Department by the French Geological Survey. One 

 of these is the large " Carte Geologique du Plateau Central," by 

 MM. Delafond, Fontannes, Fouque, De Launay, Le Verrier, Lory, 

 Michel-Le'vy, and Termier ; the other map is the " Carte Geolo- 

 gique de la France " (a l'^chelle du millioneme).
