MUSEUM OF COMPARATIVE ZOOLOGY. 33 
REPORT ON THE MYRIOPODS, ARACHNIDS, AND 
WORMS. 

By Rateu V. CHAMBERLIN. 

During the year, the collections of chilopods and diplopods have 
been much increased by contributions from the following sources :— 
Dr. C. C. Adams, duplicates of a second valuable collection made 
by himself in the Flathead Lake region of Montana; Mr. G. F. 
Sutherland, material from Douglas Lake, Michigan; Miss E. B. 
Bryant and Mr. W. F. Clapp, specimens from New England; 
Mr. J. H. Emerton, specimens from New Jersey; Professor Welch, 
specimens from Kansas, and Dr. Thomas and Mr. F. K. Barbour, 
material from St. Lawrence Co., New York. Dr. C. G. Hewitt, 
several small lots from Canada; Mr. E. O. Essig, additions from 
the fauna of California; Profs. Roland Thaxter and C. T. Brues, 
material collected on Grenada and Trinidad; Dr. C. F. Baker and 
Mr. Nathan Banks, several lots from the Philippines; Prof. P. P. 
Calvert, specimens from Costa Rica; Mr. C. T. Ramsden, speci- 
mens from Cuba; and Dr. H. L. Clark, a small but valuable series 
from Australia. The material collected by the University of 
Michigan Expedition to Colombia in 1913 has been sent for iden- 
tification. 
The Mexican material purchased of Mr. W. M. Mann has proved 
especially interesting. 
A notable addition to the collection of Arachnida was that of 
the entire lot of very important material secured by the Yale 
Peruvian Expedition of 1911. For this gift the Museum is in- 
debted to Prof. H. W. Foote, the principal collector. Specimens 
have also been received from Miss E. B. Bryant from the New 
England fauna; from Mr. C. T. Ramsden, Cuba; Dr. Thomas and 
Mr. F. K. Barbour, New York; Mr. S. C. Chamberlin, Utah; and 
Dr. H. L. Clark, the Australian region. 
Specimens of worms have been added by Drs. H. B. Bigelow and 
Thomas Barbour, and by Mr. W. F. Clapp. 
During the year, my time was devoted largely to the continua- 
tion and essential completion of the work upon the North American
