deep-sea origin which also have industrial uses. Dr. B. E. Dahlgren 

 during his stay in Florida and other southern states collected for the 

 department about one hundred and thirty geological specimens chiefly 

 from Florida, but also from localities in Kentucky and Tennessee. These 

 included sixteen specimens of varieties of soils, marls, mucks and sands 

 characteristic of certain portions of Florida; several large specimens of 

 coquina, illustrating the varieties and forms which characterize the 

 structure of this peculiar aggregate, and ninety specimens of inverte- 

 brate fossils, partly from recent formations in Florida and partly from 

 formations of Chester age in Kentucky and Tennessee. 



The principal accession during the year in the Division of Mammal- 

 ogy was secured by gift from Col. Dale Bumstead of Oak Park. It 

 consists of three well-prepared skins and skulls of the Lower California 

 moimtain sheep and several skulls of mule deer. The Division of 

 Ornithology received 217 bird skins, 67 of which represent a part of the 

 Museum's share from the CoUins-Day expedition. An African elephant 

 skull and a white rhinoceros skull were received as an exchange from 

 the American Museum of Natural History. Among the additions made 

 to the shell collection is a gift from Mr. Giuseppe Despott of the Natural 

 History Museum in Malta, which consists of 433 named and well labeled 

 specimens from the Maltese Islands. The fact that the Museum had 

 few sheUs from these islands adds to the value of this acquisition. There 

 were 949 shells and 10 crustaceans added to the Department during the 

 year. A total of 63 specimens of insects was received, of which ntmaber 

 57 were a gift and 6 an exchange. The accessions in the Division of 

 Ichthyology and Herpetology consisted chiefly of gifts, totaling 284 

 specimens. The most important of these is a collection of thirty amphi- 

 bians and reptiles from the Mississippi River Valley, presented by 

 Mr. J. W. Mackelden of St. Louis. Mr. Leon L. Pray, Mr. William J. 

 Gerhard, Mr. Herbert L. Stoddard, and others, added a number of 

 desiderata to the collection of Illinois and Indiana snakes. Mr. Stoddard 

 also donated a collection of wall lizards, taken by him while in the service 

 in France. Mr. J. G. Sinclair presented a few amphibians and reptiles 

 from Arizona, Mr. M. H. Sackheim three from New Mexico, and Mr. 

 Charles L. Hubbs several from southern California. 



Expeditions and Field work. — Finds of remains of mastodon at two 

 localities, Monee, Illinois, and Leiter's Ford, Indiana, were investigated 

 by Assistant Curator Riggs. The mode of the occurrence of the bones at 

 these locaHties was studied, some exploration conducted at the sites and 

 negotiations entered into with the owners of the specimens which may 

 result in securing desirable material later. As a result of a trip to 

 Porcupine, Ontario, Canada, gold-mining district, a ntmiber of typical
