Accessions— Geology 



Notable additions to the collection of fossil invertebrates include a 

 splendid Pennsylvanian (Coal Age) insect from Nova Scotia, the 

 gift of Dr. James E. Canright. Dr. Willard P. Leutze donated 22 

 fossil eurypterids, including several specimens of very rare species, 

 all collected by him in the Silurian of West Virginia. Among the 

 specimens collected during the summer by Curator Denison and 

 Chief Preparator Gilpin are 113 trilobites, 15 crustaceans, and 7 

 other fossil invertebrates from the Middle Cambrian Stephen for- 

 mation, exposed high on the flank of Mount Stephen in British 

 Columbia. These well-preserved specimens are from a spot very 

 close to C. D. Walcott's famous Burgess Pass locality and repre- 

 sent essentially a lateral development of the fauna restored in the 

 Museum's Cambrian habitat group (Hall 37). 



Sixty-five specimens of Eocene fishes from Monte Bolca, Italy, 

 were received as the first part of an exchange from the Museo 

 Civico di Storia Naturale in Milan (the Monte Bolca locality is 

 famous for the large variety and excellent preservation of its ma- 

 rine fishes, many of which are closely related to living forms). A 

 small collection of Asiatic fossil mammals, which was purchased 

 from Robert Somerville, was added to the collection of fossil mam- 

 mals. Two gifts of selected fossil plants collected in the Eocene 

 of Wyoming and Tennessee by the Robert H. Whitfield family 

 considerably enriched the fossil-plant collections. Dr. Edward P. 

 Henderson presented a polished slice of Bonita Spring meteorite, 

 a fall not represented in the Museum's meteorite collection. 



Care of the Collections— Geology 



The purchase of 44 new steel storagecases has relieved overcrowd- 

 ing in the collections of fossil invertebrates and plants. Specimens 

 temporarily stored in boxes have now been added systematically 

 to the study collection, where they are readily available for refer- 

 ence. At the same time, the collection of fossil fishes has been 

 moved to new quarters, where the specimens are much more acces- 

 sible. David Techter, Assistant in the Division of Fossil Verte- 

 brates, spent considerable time in reorganizing the collections. 



In the Division of Mineralogy and Petrology work continued 

 on the identification, cataloguing, and labeling of the several thou- 

 sand mineral specimens obtained in the Nelson Collection (see 

 Annual Report 1958, page 63). A complete card index of the
