Nota: Cette espèce est proche de C. longimana. La présence caractéristique d'une coloration noire aux extrémités des pattes natatoires ne semble pas toujours assurée.

Chart showing the geographical distribution in the seas surrounding the Antarctic continent.
Nota: In this chart the area frequented by whaling vessels has been hatched. The Antarctic circle (66°.5 S) has been drawn as a broken line. The numbers I to VI refer to the sectors into which the Antarctic seas are divided according to Mackintosh (1942) (after Vervoort, 1951).

Geographical glossary

Antarct. (Peninsula, SW Atlant., Weddell Sea, South Georgia, SE Atlant., Indian, SW Pacif.), Atlant. tropical (11°N, 37°W) (in Wilson, 1942 a, p.31, 175), Sargasso Sea : off E Cape Cod (42°N, 64°30'W, in Harding, 1974), Greenland (Davis Strait) (in/em> Jespersen, 1934)

Dimensions (mm)

References of the authors concerning dimensions

(25) F: 3,92; (31) F: 3,91; (35) F: 3,7; M: 3,5-3,33; (49) M: 3,8-3,3; {F: 3,70-3,92; M: 3,30-3,80}

The mean female size is 3.843 mm (n = 3; SD = 0.1242), and the mean male size is 3.483 mm (n = 4; SD = 0.2293). The size ratio (male : female) is about 0.91.

Remarks

Meso-bathypelagic.
Sampling depth (Antarct.) : 300-1000 m. In vertical tow 2000-1000 m (Harding, 1974).
The presence of this species in the north Atlantic needs confirmation.
