34 ANNUAL REPORT OF THE 
Lithobiomorpha. Several papers presenting results of revisions 
of sections of this group were prepared; and the rearranging and 
relabeling of the specimens was completed. In addition a study 
was made of the chilopod fauna of the West Indies and of part of 
that of Mexico and a report was prepared presenting some results 
of this investigation. Routine work involved the study of a 
considerable number of collections of myriopods sent in for identi- 
fication. 
About ten days of August were spent in field work in New Hamp- 
shire and Maine, attention being given primarily to the chilopods 
and diplopods. A week in March was given to collecting in 
Minnesota, chiefly in the neighborhood of Winona, the purpose 
being to clear up the identity of several species that had been 
described from that locality. For several weeks in June and 
July I was in the field, chiefly in the Wasatch Mountains of Utah, 
where the arachnids were made the special object of study, much 
valuable material in this group being secured. The arthropod 
fauna of several caves in these mountains was investigated.
