kiss, State Geologist, and Dr. E. O. Ulrich, and some 500 specimens 

 of Middle and Upper Devonian fossils, a gift of Mr. E. G. Arm- 

 strong of Erie, Pennsylvania, greatly enriched the study collections 

 of invertebrates, and Mr. Arthur E. Morgan. Chief Engineer of the 

 Miami Conservancy District, Dayton, Ohio, donated an exhibition 

 specimen of exceptional value in form of the largest known Amer- 

 ican trilobite, measuring IT inches in length ami representing a 

 newly described species. There were also received as an exchange 

 tli rough Ward's Natural Science Establishment, 27 specimens of 

 fossils, 14 of which are types. 



One of the most valuable accessions to the section of vertebrate 

 paleontology was a deposit from the Maryland Geological Survey, 

 comprising 78 individual items, of which 74 are either types or fig- 

 ured specimens, 13 being the original types of the following species: 

 Promarus dtteni Gregory and Berry; Istiophorus calvertensis Berry; 

 Tretulias buccatus Cope ;-BaZaenoptera sursiplana Cope; Prisoodel- 

 phinus crasmngulum Case; Cephalotropis coronatus Cope; Mylio- 

 batus copcanus Clark; Amyda virginiana Clark: Xiphias (?) radi- 

 ata Clark; Synechodus clarkii Eastman: Carcharias incidens East- 

 man; Squatina occidental}* Eastman; and Thecachampsa mary- 

 Iqndica Clark. While but few of these are suitable for exhibition, 

 the specimens are a valuable addition to our rapidly increasing- 

 series of type material. 



Of equal importance are gifts of Pleistocene mammal bones and 

 teeth, comprising 35 specimens from a cave near Bulverde, Bexar 

 County, Texas, donated by Dr. O. P. Hay; about GO specimens from 

 Cavetown, Maryland, gift of Phillips Academy, Andover, Massa- 

 chusetts, through Doctor Hay: and a small collection including frag- 

 mental remains of the horse and camel, from Washtucna Lake, Wash- 

 ington, obtained many years ago by General George M. Sternberg 

 and presented in his name by Mrs. Sternberg. 



By exchanges were acquired an unusually "complete mounted skele- 

 ton of an extinct camel, Stenomylus hitckcoc/d, from the important 

 Miocene deposits at Agate Springs, Nebraska; the type specimen of 

 the fossil bird, Jabiru weillsi Sellards; and two sets of Moa leg bones 

 and one lot of crop stones, from New South Wales. The first of 

 these was received from Carnegie Museum, Pittsburgh, Pennsyl- 

 vania, and is now on exhibition; the second from the Geological Sur- 

 vey of Florida, and is important on account of the rarity of fossil 

 bird remains; and the third from the Public School, Lake Bathurst, 

 New South Wales. 



Two enlarged photographs of Knight's restorations of Brontothe- 

 rium and Tylosaumx, and a model restoration of a mastodon were 

 acquired by purchase.
