STUDIES IN NEOTROPICAL MALLOPHAGA—CARRIKER 201 
the length of those in aberrans, the paramers less and the endomeral 
plate much less than half the length of those in both mewicanus and 
aberrans. The most striking difference is in the endomeral plate, 
which is not elongated into a slender, needlelike point but is abruptly 
truncate and extends but little beyond the middle of the paramers. 
This character, in connection with the small size, has led me to give 
taoz specific rank, since it differs from all other known forms in this 
respect. The differences between taoz and colombianus are given 
under the latter.

Genus PECTENOSOMA Ewing 
PECTENOSOMA VERRUCOSA (Taschenberg) 
Goniocotes verrucosus TASCHENBERG, Die Mallophagen, pp. 68, 94, pl. 3, fig. 4, 
male, 1882. (Host: Crypturellus variegatus.) 
When my “Lice of the Tinamous,” 1936, was published I had seen 
no material of this species from the type host, but I assumed that a 
single female from C. variegatus salvini, as well as numerous males 
and females from C’. undulatus yapura, was the same as Taschenberg’s 
type. My drawing of the female was made from the specimen taken 
on C. v. salvini, while the male genitalia were taken from a specimen 
off C. u. yapura. 
Miss Clay (1937, p. 155, fig. 18) subsequently published a note on 
this species, stating that she had compared specimens of P. verrucosa 
from C. v. variegatus with others from C. variegatus salvini and found 
them to be the same, but that those from @. undulatus yapura were 
slightly different. Her figure of the genitalia of true verrucosa amply 
substantiates this statement, so that the figure published by me of the
