yapurae, from which it differs in having the general line of the sides 
of the head straight (but slightly undulating), while in yepurae there 
is a marked convexity just back of the antennal fossae, and the temples 
are decidedly concave on both outer and inner margins. The scent 
gland is short and mre thickened (see fig.), differing from all the 
other races. 
The measurements of this race are given together with HM. m. 
yapurae, which follows.

FIGURE 12, e, f 
Type.—Male, adult, from Crypturellus. undulatus yapura, collected 
by the author at Puerto Yessup, Peru, February 19, 1930; in collection 
of author. 
Diagnosis.—This race is represented by a single male, the type. It 
is distinguished by the wide, flattened front of the head, concave, 
slender, rather widely divergent temples, and by characters of the 
male genitalia. 
The genitalia are of medium size, narrow at base of paramers, and 
with wide basal plate; the endomeral plate is also narrow, with slender 
secondary, lateral plates (more or less superimposed) ; short, slender, 
divergent prongs and crescent-shaped internal chitin struts. The 
scent gland is long and narrow, very similar in this respect to #. m. 
NiGriceps.
