28 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1945 



although small, is unusually well preserved, and contains interesting 

 examples of tooth mutilation and cranial deformity. The teaching 

 and research supplemented one another as the Xochicalco collection 

 was used for demonstration purposes, particularly as regards restora- 

 tion, sexing, aging, and pathological changes. Much interest in this 

 field of research has developed as a result of this work. 



A third project was concerned with work in Haiti for the Museum 

 by Dr. Alfred Metraux, of the Institute of Social Anthropology, from 

 September 18 to November 30. His investigations concerned anthro- 

 pology and were made in cooperation with the Bureau of Ethnology 

 of Haiti and the Scientific Society of Haiti. For a month Dr. Me- 

 traux conducted cooperative archeological investigations on Tortue 

 Island in the north, and for another month he was in Port-au-Prince 

 engaged in lectures and anthropological investigations. During the 

 entire period Dr. Metraux maintained close contact with the Scien- 

 tific Society for which he organized seminars for the discussion of 

 anthropology. 



In continuation of the ornithological reconnaissance of northeast- 

 ern Colombia, M. A. Carriker, Jr., of Santa Marta, went into the field 

 to complete examination of the valley separating the Sierra Nevada 

 de Santa Marta from the Sierra Peri j a. At the end of the fiscal year 

 he had moved into the lower elevations of the Sierra Nevada where 

 this range extends to the east toward the Guajira desert. Excellent 

 results were reported in additional specimens for our rich collections 

 from this area. This work is financed by the income of the W. L. 

 Abbott fund. 



A few local collections have been made by Dr. Leonard P. Schultz 

 and Dr. Robert R. Miller, curator and associate curator of fishes, re- 

 spectively, who secured fossils at Scientists Cliffs, on Chesapeake Bay, 

 and fishes from various creeks in the State of Maryland. Several 

 of the insect specialists have made extensive, largely local, collections 

 within their own groups, some 3,000 specimens being added to the 

 national collections through these efforts, a number being forms new 

 to the collections, especially in the case of coleopterous larvae and 

 the Aleyrodidae. Most of the aleyrodid material was obtained by 

 Miss Louise Russell from preserved plant material at the National 

 Herbarium and in the Herbarium of the New York Botanical Gardens. 



Dr. G. Arthur Cooper, curator of invertebrate paleontology, in 

 company with Dr. Byron N. Cooper, of the Virginia Geological Sur- 

 vey, carried on further investigations in the complicated geology and 

 paleontology of the nearby Appalachian Valley, during two brief field 

 trips. The first, in June 1944, covered parts of this area as far north 

 as southern Pennsylvania and south to Staunton, Va., to study facies 

 changes in the Ordovician limestone (Chambersburg formation) from 

 its type area near Chambersburg, Pa., to a point in the vicinity of
