plumosus, a species which has not been reported from Trinidad. This 

 species together with others of the association are the common con- 

 stituents of the savannas fomid on the Pacific slope of Panama and 

 Central America. In this savanna was found an undescribed species of 

 Axonopus, a beautiful golden annual, allied to A. aureus. At Taba- 

 quite in the center of the island in the original forest or "High woods" 

 was found another undescribed species of Raddia and the rare Pharus 

 parvifolius Nash. Several other apparently undescribed species were 

 found on various parts of the island. Most of the species, whose types 

 were from Trinidad were re-collected at their type localities. The re- 

 sults of the expedition to Trinidad and to Jamaica visited earlier on the 

 same trip, were very satisfactory and will supplement the large West 

 Indian collections previously incorporated in the National Herbarium.

THE BIOLOGICAL SOCIETY OF WASHINGTON 



The 508th regular meeting was held in the assembly hall of the Cos- 

 mos Club February 22, 1913, with President Nelson in the chair and 

 76 persons present. 



The program consisted of a lecture by Edmund Heller on Hunting 

 with Rainey in Africa. The communication was chiefly descriptive of 

 the maps and numerous lantern slides exhibited and also of the physical 

 features and vegetation of the country, as well as the animals secured 

 during the expedition. 



The 509th meeting was held March 8, 1913, with Vice-President Paul 

 Bartsch in the chair and 37 ]:!ersons present. 



Under the head of Brief notes and exhibition of specimens, Wm. Pal- 

 mer exhibited the head of the small devil ray, Mobtda olfersi, and a 

 plaster cast made from the same, and explained the feeding habits of 

 this fish. A. C. Weed gave some further account of its habits, and 

 Theodore Gill added some historical notes about devil fishes. 

 Barton W. Evermann reported results of the sale of blue fox skins 

 from the Pribilof Islands at Lampson's (London) auction on March 7. 

 The 384 skins offered sold at an average price of $56, the highest price 

 being $85. 



The regular program consisted of two communications: J. W. Gid- 

 LEY gave an account of a fossil camel recently found in America north 

 of the Arctic circle. The only bone found was a phalanx. The species 

 was an extinct one and its occurrence so far north was regarded as 

 further proof that there once existed land coimection between the 

 continents by way of Alaska. The paper was discussed by Messrs. 

 Wilcox, 0. P. Hay, Weed, Gill, Evermann, Lyon and others. 



The second communication was by Paul Bartsch on some Remark- 

 able Philippine molluska obtained by the U. S. Bureau of Fisheries expe- 

 dition. Specimens of the mollusks described were exhibited by the 

 speaker.
