like, the third exopodal segments of swimming 
feet 1 to 4, and the f ureal setae. 
The pertinent measurements and ratios of 
the adult males are presented in Table 1. The 
posterior lateral angles of the male cephalo • 
thorax (Fig. 16) are produced into asymme- 
trical processes. The left is sharp and reaches to 
the posterior margin of the genital segment. 
The right process (Fig. 18) is thick and slightly 
curved inward and reaches to a line including 
one-quarter of the length of the second abdom- 
inal segment. In lateral view (Figs. 17, 19), this 
right process is thick and truncate with a con- 
vex dorsal margin and a concave ventral margin. 
The male genital segment (Fig. 18) is asym- 
metrical with a rounded swelling tipped with 
a small button on the right side. In lateral view 
(Fig. 19) the swelling appears as two or three 
concentric, incomplete circles. The left posterior 
margin of the genital segment Is broken by the 
genital opening. In the allotype, a canal is vis- 
ible from the genital opening to a sperma- 
tophore (Fig. 18). 
The geniculate right antenna (Fig. 20) is 
armed with coarse, unequal pigmented teeth on 
segment 18, fine pectination on segment 17 ex- 
tending onto the anterior margin of a distal 
spinous process, and very fine pectination on 
segment 19. Segments 17, 18, 19, and 20 are 
separate. 
The right fifth foot ( Fig. 2 1 ) is chelate with 
the tip of the distal segment reaching slightly 
beyond that of the penultimate segment. The 
terminal spine is turned flat against the surface 
of the distal segment. The left fifth foot is 
broad and ends in a spatulate segment (Fig. 
21 ). 
Pigmentation is similar to that of the female. 
In addition, the geniculate portions of the right 
first antenna are heavily pigmented. There is no 
pigmentation on the right thoracic process or 
the genital segment. 
remarks: The female of C. pofi resembles 
C. cheimra Cleve (as described by Farran, 1929) 
in having ventral protuberances on the genital 
and second abdominal segments, and thick ex-
