granulations. Antennal scale with spine noticeably exceeding blade and separated 
from it by a deep incision for about the distal fourth of its length. First two 
abdominal segments obsolescently carinate dorsally, third carinate on anterior half, 
fourth on anterior two-thirds, and fifth throughout its length; sixth abdominal 
segment with a median suleus formed by two nearly parallel carinae, diverging 
somewhat anteriorly; these carina are paralleled on each side by another carina 
which anteriorly diverges even more from the median line; abdominal segments 
one and two are each armed laterally with a single spine, while the third segment 
has a subacute downward projection near the anterolateral angle; in the male 
this projection is obsolescent or entirely lacking; fourth and fifth segments with 
posterolateral angle acute. Telson exceeding inner branch of uropods, which in 
turn exceeds the outer branch; tip acute and armed in the male with three pairs 
of lateral spinules and in the female with four. 
Ventrally the thoracic sternum of the male has an anteriorly directed spine 
between the bases of the second pair of legs, and a thin, laterally compressed keel 
between the bases of the following three pairs of legs. In the female there is a 
low, blunt tubercle between the bases of the second pair of legs. The first, second, 
and third abdominal segments of the male are armed below with a prominent, 
acute median spine; the fourth has a less prominent blunt spine; and the fifth 
has only a low tubercle; the sixth segment is ventrally unarmed. The abdomen 
of the female ventrally unarmed except for a small obsolescent tubercle between 
the pleopods of fifth segment. 
Dimensions.—Type male, holotype (Cat. No. 52714, U. S. N. M.): length from 
tip of rostrum to end of telson 35 mm., length of carapace and rostrum 11 mm., 
of hand about 6 mm.; of female, total length 44 mm., of carapace and rostrum 
13 mm., of hand 7 mm. 
Type Locality—Off Point Loma, California, 525 to 541 fathoms, 1 male 
(‘‘ Albatross’’ station 4334). 
Distribution.—The only other specimen of this species, a female, was also 
taken off Point Loma, 628 to 640 fathoms (‘‘Albatross’’ station 4353). 
Remarks.—In this species the tip of the rostral spine reaches only about to 
the middle of the ocular peduncle; in C. spinosissima it reaches to the cornea 
but does not exceed it; and in C. spinirostris (Rathbun, 1904a, p. 131), another 
closely related species, the tip of the rostral spine exceeds the eyes.

Characters.—Second lateral carina of the carapace (counting from the middle) 
armed with a spine a little behind the superior lateral spine. First to fourth 
abdominal segments smooth. Hands two and one-half times as long as wide, 
swollen, the anterior margin more longitudinal than transverse.
