52 REPORT OP NATIONAL MUSEUM, 1925 



The survey of the fisheries of the Republic of Salvador, Central 

 America, by Samuel F. Hildebrand and Fred J. Foster, of the 

 United States Bureau of Fisheries, was undertaken at the request 

 and at the expense of the Salvadorean Government. Their explora- 

 tions extended over the early part of 1924. As a result the bureau 

 has transferred to the Museum a large collection of Salvadorean 

 fishes and some crustaceans. 



The geological expedition of Dr. C. D. Walcott into the Canadian 

 Rockies, like those of previous years, has added valuable speci- 

 mens which will be utilized in the contemplated remodeling of a 

 group representing a family of Rocky Mountain sheep in the 

 American mammal hall. 



The collections of the Museum have profited likewise from several 

 expeditions where the collecting of zoological objects wasi more or 

 less incidental, such as the expedition undertaken by Capt. R. A. 

 Bartlett for the National Geographic Society in Bering Sea and 

 Arctic America during the summer of 1924; and the Bowdoin 

 expedition of 1924 to Greenland under the conunand of D. B. 

 Macmillan. 



Explorations which have contributed valuable material to the 

 National Herbarium during the fiscal year 1924-25 are as follows: 

 In August, 1924, Paul C. Standley, associate curator, was detailed 

 as a member of the Carlsbad Cavern expedition of the National 

 Geographic Society, and in the course of several weeks' field work 

 in the region of the cavern collected about 600 specimens, many 

 of which represent species not previously known from New Mexico. 

 A popular account of the vegetation of the Carlsbad Cavern region 

 has been prepared for publication, largely on the basis of this 

 field work. Mrs. Agnes Chase, assistant botanist in the Bureau 

 of Plant Industry, was detailed by the Department of Agriculture 

 from October, 1924, to June, 1925, to field work in the eastern 

 highland region of Brazil for the purposes of collecting grasses, 

 in cooperation with the Field Museum of Natural History, the 

 Missouri Botanical Garden, the Gray Herbarium of Harvard Uni- 

 versity, and the New York Botanical Garden. Upwards of 10,000 

 specimens were collected, representing nearly 2,500 collection num- 

 bers. About one-half of the grasses known previously from Brazil 

 were collected, besides material in other special groups.

CONDITION OF THE COLLECTIONS 



Completion of the hew Rocky Mouiltain goat group forms the 

 main achievement of the taxidermists during the present year. This 

 group, which replaces one mounted many years ago, represents a
