48 EEPORT OP NATIONAL MUSEUM, 1925 



the division obtained 30 specimens of isopods {Paragnathia formica) 

 from France. A number of microscopic slides of isopods, Pale- 

 arctic and Australian, were also acquired from Dr. K. W. Verhoeff. 

 The type of Pylopagurus schndtti was received from the describer, 

 Miss Belle A Stevens, University of Washington, Seattle. 



MolUisTcs. — In addition to his work with beetles the late Col. 

 Thomas L. Casey was greatly interested in certain groups of mol- 

 lusks, and extensive collections of these were included in his be- 

 quest. Thus about 1,000 specimens of recent mollusks, embracing 

 many genotypes of the family Turritidae, came to this division. 

 Truman H. Aldrich, of Birmingham, Ala., donated 146 specimens 

 of land and freshwater shells from India, including types of three 

 species of Alcaeus. Dr. Hugh M. Smith this year again forwarded 

 a large sending comprising 350 specimens of mollusks from Siam. 

 Approximately 700 species thus far have been contributed by him 

 from that region. Mr. D. Thaanum, of Honolulu, T. H., sent 153 

 specimens representing 46 species of marine shells from Hawaii, 

 Japan and the Western Pacific, mostly of species not included in 

 his previous large donations. Dr. Julia Gardner, of the United 

 States Geological Survey, presented the museum with about 1,000 

 specimens, including 35 species, from Porto Rico. Dr. H. Pittier 

 at Caracas, Venezuela, has supplemented his previous sendings from 

 that country by 253 specimens, representing 23 species, so that our 

 collections from that region are now fairly comprehensive. Dr. 

 Paul Bartsch, the curator, collected about 2,700 specimens of Cerions 

 in Cuba and the Florida Keys, and in collaboration with William 



B. Marshall, the assistant curator, about 2,500 specimens of marine 

 mollusks at Cape May, N. J. Manly D. Barber, Daytona Beach, 

 Fla., donated 38 specimens, including types of three species and a 

 paratype of a fourth. Mrs. I. S. Oldroyd, of Stanford University, 

 presented about 40 specimens including the types of two new species. 

 For further type material the Museum is indebted to Mrs. Agnes 

 Chase, E. P. Chase, T. D. A. Cockerell, L. A. Faustino, H. C. Hig- 

 gins, A. M. Strong, and Bryant Walker. 



The income from the Frances Lea Chamberlain Fund has enabled 

 the curator to secure for the Museum some very important material 

 which it would have been difficult to obtain, otherwise than by pur- 

 chase, including a number of topotypes of Cerions described by 



C. J. Maynard, as well as four species (genotypes) not before in the 

 Museum. 



Section of hel/rmnthological collections. — The largest collection 

 received was from Frits Johansen, Department of Marine and Fish- 

 eries, Ottawa, Canada, and included 700 specimens of helminths 

 from Arctic Canada. Dr. G. A. MacCallum, Baltimore, Md., do- 

 nated the type and paratype of Ca'pillaria carcJiarini^ and J. P. van
