kiss, State Geologist, and Dr. E. O. Ulrieh, 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 INIr. Arthur E. ^Morgan, Chief Engineer of the 

 ]Miami Conservancy District, Daj'ton, Ohio, donated an exliibition 

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

 ican trilobite, measuring 17 inches in length and representing a 

 neAviy described species. There were also received as an exchange 

 through Ward's Natural Science Estal)lishment, 27 specimens of 

 fossils, 14 of Avhicli 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 Avhich 71 are either types or fig- 

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

 Promarus alleni Gregory and Berry: Istiopliorus calvertemis Berry; 

 TretuJias huccatiis Cope; Balaenoptera sursiplana Cope; Priscodel- 

 phinus crassangulum Case; Cephalotropis coronatus Cope; Mylio- 

 bcttus copeanus Clark; Amyda virginiaiia Clark; Xiphias (?) racU- 

 ata Clark; Synechodus clarkii Eastman; Carcharias Incldens East- 

 man; Squafina occidentcd'is Eastman; and Tln'cachampsa mary- 

 Jandica 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 CO specimens from 

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

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

 the fossil bird, Jdbiru iceillsi Sellards ; and two sets of Moa leg bones 

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

 these was received from Carnegie INIuseum, Pittsburgh, Pennsyl- 

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

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

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

 Xew South Wales.
