REPORT OF THE MYRIOPODS AND ARACHNIDS. 



By Ralph V. Chamberlin. 



During the year, additions to the collections of chilopods and 

 diplopods have been received from Miss E. B. Bryant and from 

 Messrs. J. W. Bailey, C. T. Brues, H. L. Clark, A. J. Cook, J. J. 

 Davis, J. H. Emerton, H. W. Henshaw, W. A. Hilton, J. D. 

 Mitchell, E. W. Nelson, W. R. Walton, W. M. Wheeler and C. B. 

 Williams. 



Accessions to the collection of arachnids were received from 

 Miss E. B. Bryant, Miss M. L. Moles, and Messrs. C. T. Brues, 

 S. C. Chamberlin, H. L. Clark, J. H. Emerton, and W. A. Hilton. 



A specimen of a new species of land turbellarian from the 

 Philippines was sent in by Dr. C. F. Baker. Specimens of nine 

 species of Chaetognatha were received from the collections of the 

 U. S. Bureau of Fisheries. 



The first months of the year were devoted chiefly to the work 

 of cataloguing. The catalogue of the chilopods and diplopods was 

 completed so far as concerns identified material. The catalogue 

 of the annelids was revised and brought nearly up to date, and 

 the collection was largely rearranged. Other routine work in- 

 cluded the study of a number of collections of myriopods and 

 arachnids sent for identification. A report on the chilopods of 

 St. Paul Island, Alaska, was prepared for the U. S. Bureau of Bio- 

 logical Survey. Most of the time from December to June was 

 devoted to work on the annelids of the Albatross expeditions of 

 1891, 1899-1900, and 1904-1905.
