Posterior thoracic margin rounded, armed 3 short spines situated rather towards the ventral side. Rostrum consists of 2 slender processes. Proportional lengths of urosomites and furca 4:3:2:2. Genital segment somewhat barrel-shaped, and has a rounded swelling on the dorsal aspect. A1 21-segmented (segments 2-4, 8-9, 24-25 fused). P5: both rami 3-segmented; exopod 1 bears a marginal spine, but has no internal seta; exopod 2, in addition to the single external marginal spine, bears the usual spine on its inner border, this spine is long and has somewhat swollen base; it tapers gradually to a fine point and bears no teeth on its surface; exopod 3 has 2 marginal spines and a finely serrated end-spine; the endopodite reaches to the level of the joint between exopods 2 and 3; endopod 1 presents a well-marked rounded swelling at its distal external angle. The remaining appendages appear similar to those of C. alcocki but the serrations on the terminal spines of the swimming feet are not so coarse and are less widely separated.
