CHAMBERLIN: THE CHILOPODA OF BRAZIL. 201 
original description. It appears not to be a true Nannophilus under 
which genus it was described, and is most probably a member of 
Schendylurus. 
ADENOSCHENDYLA Broélemann and Ribaut.

p. 194. 
Three species and one variety of this genus, which is peculiar to 
tropical and subtropical America, are known from Brazil. Of these, 
one is here first described. 
The genus is close to Pectiniunguis. Pectiniunguis and Adeno- 
schendyla lack claws on the anal legs in contrast with species of the 
southwestern United States (montereus, heathi, etc.) The latter 
species differ as well in other respects and may be placed under a 
distinct genus to be known as Nyctunguis (P. montereus Chamb., 
type).
