The shape of the P5 (as also shown by Schellenberg 1926 p. 204) leaves no doubt as to the identity of C. faurei specimens of the Magellan area.
Of the 85 specimens sampled, only 6 were adults
and all 6 were females. The only ovigerous female was 22 mm in length, as also reported by
Barnard (1932) for two ovigerous females from
the South and Southeast Atlantic, respectively.
Distribution
Lowry and Bullock (1976) report the species as
cosmopolitan with a depth range from 0-1200
m. Schellenberg (1926) reported a depth range
from 0-2500 m; Birstein and Vinogradov (1960)
a depth of 1910 m. In the Straits of Magellan,
maximum densities occurred at the Pacific entrance to the Straits. Abundances diminished
very rapidly towards the Atlantic, even though
the species was present off Pas o Larg o and Ca pe
Froward, unt il St. 15 off Pas o Ancho. The species
had a very wide vertical distribution range in
both the Pacific and Central areas, with maximum densities occurring from 100-200 m.
