Annual Meeting.] 246 [May 7, 
One hundred and twenty-five specimens of Cretaceous fos- 
sils from Texas, obtained by purchase from Mrs. D. H. 
Walker. One hundred specimens of Cretaceous vertebrate 
remains from Kansas, purchased from the State Geologist, 
Prof. B. F. Mudge. 
With these two additions, our Cretaceous collection has 
come to compare favorably with those of the other North 
American formations. 
In the New England collection I ae to note the acces- 
sion of twenty specimens of fossiliferous rock, probably of 
Eocene age, from the drift of Truro on Cape Cod. These 
were given by Mr. Warren Upham. 
Adding the foregoing to the figures submitted last year, 
the North American collection is found to consist as follows: 
Genera. Species. Specimens.

The Triassic fishes and plants, ard most of the foot-tracks, 
as well as a good collection of Devonian bivalves, and several 
other small lots of fossils which have never been identified 
and are for the most part unmounted, are not included in the 
above summary. 
The names of the corals, and of some other fossils of the 
Cambrian, Silurian, and Devonian formations have been re- 
vised, in accordance with the recently published reports of 
the Geological Surveys of Michigan and Ohio, and the fifth 
volume of the Palaeontology of New York. — 
The collection from South America, including the West 
Indies, is almost insignificantly small; and, with the excep-
