growth. This is a collection of more than ordinary value, because 

 of the great care exercised by Doctor Beecher in the selection and 

 mounting of the material.

 received a number of excellent cystids from the Silurian of Grimsby, 

 Ontario.

 chase, an excellent series of Lower Devonian starfishes and crinoids, a 

 large slab with many fine examples of JPentacrimts jwsilis, a similar

VERTEBRATE PALEONTOLOGY. 



1. The most important accession of the year was a specimen of the 

 pterodactyl, Rhamphorhynehus pkyllurus, showing the impression of 

 the wing and tail membranes. This, as well as tine specimens of 

 ichthyosaur and teleosaur {Stenosaurus) and a number of fishes typical 

 of the fauna of the lithographic limestone, was purchased for the 

 Louisiana Purchase Exposition. 



2. A cranium of Bison alien I, presented b}^ Mr. D. McLean, of 

 Rampart city, Alaska, is important from the fact that it is the first 

 specimen of this species obtained in Alaska, and because the horn 

 material itself was preserved.

The only accessions of great importance in this department were: 



1. One hundred and ninety specimens from Mazon Creek, Illinois; 

 Athens, Ohio; and other localities, which form a part of the Carl 

 Rominger collection purchased a year ago. This collection is especially 

 valuable as containing a fair representation of silicified trunks, par- 

 ticularly of the genera Ihidoxylon and Psaronins, These were accom- 

 panied by a series of well-prepared microscopic sections. 



2. One hundred and thirty-two specimens from the higher beds of 

 the anthracite series, collected and presented to the Museum by Mr. 

 C. W. Unger, of- Pottsville, Pennsylvania.
