2. Megalocranchia fisheri (Berry, 1909)
Helicocranchia Jisheri Berry, 1909
This has only been taken in Pailolo Canal, Hawaii (Berry, 1909,
1914a) where it was dredged at 510 m on an ooze bottom. The mantle
length was approximately 4.65 cm.
3. Megalocranchia maxima Pfeffer, 1884
Desmoteuthis mximu Pfeffer, 1900
Taonius maximus Hoyle, 1886
This has been recorded from the Cape of Good Hope (Pfeffer, 1884)
and from Japanese waters (Sasaki, 1920, 1929a). Off Japan it was
taken at 660 m. A male 6.0 cm in mantle length is mature (Sasaki,
1929a) and the largest specimen has a mantle length of 6.3 cm (Sasaki,
1920).
4. Megalocranchia papillata (Voss, 1960)
Easily distinguished by the papillae on the mantle and funnel this is
only known from the type which was caught at 32'05'N, 64'38'W in an
open net fished at about 600-700 m (with 1500 m of wire out). The
mantle length of this male is 4.0 cm (Voss, 1960a).
5 . Megalocranchia pardus Berry, 1916
A Pacific species, this has been recorded from the Kermadec islands
(Berry, 1916a), New Zealand (Dell, 1952) and possibly off eastern
Australia (Allan, 1945). The type was stranded and the other specimens were taken near the surface. The largest specimens have a mantle
length of 5.0 cm (Berry, 1916a; Dell, 1952).
P. Helicocranchia
The separation from Megalocranchia of some species under the
name Helicocranchia is possibly not justified although the type of the
latter genus differs in having pedunculate fins.
1. Helicocranchia pfefferi Massy, 1907
Teuthowenia (Helicocranchia) pfefferi Bouxin and Legendre, 1936
Muus (1 956) placed this in synonymy with Desmoteuthis megalops
(see Taonius megalops below) but until more evidence can be produced
it seems better to keep it a distinct species.
It has only been recorded from waters south-west of Ireland (Massy,
1907) and with some hesitation in the Bay of Biscay (Bouxin and
Legendre, 1936). There is some confusion over the depth at which the
