REPORT OF NATIONAL MUSEUM, 1919. 85 



containing manj new and rare forms, is due to the generosity of 

 Mr. C. M. Weber, Balabac Island, Philippine Islands. A large 

 number of invertebrates from the coast of California were received 

 from Mr. E. P. Chase, of Los Angeles, California, in exchange and 

 as gift, among them the type of a new species. Types of three new 

 species of shells from the Philippine Islands were contained in a 

 donation by Mr. Gilbert S. Perez, industrial supervisor, Lucena, 

 Tayabas. Various types were also presented, with other valuable 

 material, by Mr. G. Willett, of Los Angeles, California, Mr. T. 

 Urita, Kogoshima, Japan, and Prof. Carl C. Engberg, of the Uni- 

 versity of Nebraska, Lincoln, Nebraska. 



With regard to the condition of the collections. Dr. Paul Bartsch, 

 the curator, reports that all collections have been overhauled and 

 as far as possible put in order, solutions, containers, and labels 

 renewed in all cases where necessary. The mollusk collection, as 

 a whole, has been rendered more useful by the intercalation of 

 label blocks containing the names of the genera and subgenera at 

 the head of the various sections and by cards placed in each drawer 

 showing the species contained. For a number of years Dr. W. H. 

 Dall, the honorary curator of mollusks, has been adding to the col- 

 lection of Brachiopoda by exchange or purchase. He has now sys- 

 tematically arranged this collection, bringing the nomenclature and 

 labeling up to date and naming the unidentified specimens. Includ- 

 ing the European specimens in the Jeffrej^s collection the number of 

 species represented in our series of recent Brachiopoda is 175, repre- 

 sented by more than 6,000 specimens. Thirty-two of these species are 

 new to science. From information recently received in regard to 

 the Davidson collection of recent Brachiopods now in the British 

 Museum, which has always been considered the finest in any museum, 

 it is apparent that the collection in the National Museum far 

 exceeds it, both in number of specimens and species, and of original 

 types. It is without doubt the finest collection of recent Brachiopods 

 extant. 



Doctor Dall completed the revision of the collection of mollusks 

 from the west coast of America. In the course of this work many 

 new species were discovered and described, being the largest contri- 

 bution to the marine molluscan fauna of the Pacific coast since 1886. 

 He also prepared a check list of the marine gastropods from the 

 Arctic Ocean to San Diego, California, containing references to 

 2,055 species exclusive of cephalopods and nudibranchs as against 

 only 492 species, including these groups, in Carpenter's list published 

 in 1872. He furthermore revised for publication the large collec- 

 tion of recent brachiopods, comprising over 6,000 specimens repre- 

 senting 175 species, of which 32 are new to science, and began a study
