D ANNUAL REPORT OF THE 



Large accessions have been made to the Entomological collec- 

 tions by gift, exchange, and by the field-work of the Curator. Mr. 

 Banks's duties also involve assistance to the many students who 

 consult the collection. Aside from his curatorial service, Mr. 

 Banks has prepared papers on the termites (white ants) of the 

 United States, of Panama, and of the West Indies. His taxo- 

 nomic work also includes descriptions of new Hymenoptera, 

 Diptera, and Neuroptera. As a recognized authority upon the 

 Arachnida, Mr. Banks not infrequently receives collections of 

 this class of which he has not official charge, and reports upon the 

 same. 



Though Dr. Chamberlin as Curator of the myriopods, arachnids, 

 and worms gave a part of his year's work to each of these groups, 

 by far the larger portion of the time was given over to a study of 

 the chilopods and diplopods of the West Indies and the islands of 

 the Pacific, a study which has added the types of more than 

 300 new species to the collection. Dr. Chamberlin has also 

 worked over and prepared a report upon the Pacific Coast anne- 

 lids collected by Mr. Agassiz in 1859-1860. Several collections 

 of arachnids and worms have been received for study and report, 

 duplicates from which will be retained by the Museum. 



Mr. W. F. Clapp has identified, labeled, and catalogued the 

 very considerable accessions to the collection of Mollusca; these 

 with few exceptions are distributed systematically. The Pelecy- 

 poda, exclusive of the Unionidae, have been rearranged, a work 

 which makes the entire collection readily available. Governor 

 Forbes's Philippine shells and the Winkley collection have been 

 already mentioned; other important accessions include a large 

 series of Unionidae from the Boston Society of Natural History, 

 one hundred and twenty-six species, nearly all new to the Museum, 

 from the University of Colorado, and many Cuban land shells 

 from Dr. Thomas Barbour. 



Dr. H. L. Clark states that more than 1,000 specimens have 

 been added to the collection of echinoderms during the year, 

 all of which have been identified, labeled, and catalogued. He 

 has prepared reports, complete or partly so, upon the echinoderms 

 of South African waters and upon the holothurians and sea-stars 

 collected during the Albatross expeditions to the Tropical 

 Pacific. 



Dr. H. B. Bigelow's services for the government of the United 

 States gave him very little time for his Museum duties as Curator 

 of Coelenterates. He has cared for the accessions received and 

 studied the medusan collections and data to be used for reports
