REVIEW OB THE SYSTEMATICS AND ECOLOQY ow OCEANIC SQUIDS 179
C. Enoploteuthis
1. Enoploteuthis anapsis Roper, 1964
This recently described species has been caught at various positions
in the North Atlantic from the Gulf of Mexico to Madeira and south
to 19'16's 01'48'W (Chun, 1910a; Roper, 1964, 1966). Specimens were
taken with an open net fished to as much as 2 000 m (Roper, 1964,
1966) and to as little as 10 m.
A male is mature at a mantle length of 5.4 cm and a female at
1.69 cm. The largest male specimen is 7.9 cm and largest female
is 7-69 cm in mantle length. The distal third of the right ventral arm is
hectocotylized. During growth the arms and tentacles remain the
same length relative to the mantle length while the fin becomes relatively longer and the mantle relatively narrower (Roper, 1966). There
is little change in proportion between 1.69 and 7.69 cm mantle length.
A specimen was taken from the stomach of Aphanopus carbo (Roper,
1966).
2. Enoploteuthis chuni Ishikawa, 1914
This is a Japanese species taken at Uwodo, Japan Sea (Ishikawa,
1914), Toyama Bay (Sasaki, 1929a) and at 32' 36"
132'23'E (Sasaki,
(1920). I n one instance two were taken from the stomach of a fish
which was caught at 800 m. It is often caught mixed with large
schools of Watasenia scintillans on the coast of Etchu Province (Sasaki,
1929a). The largest male described had a mantle length of 6.3 cm and
the largest female a mantle length of 9.0 cm.
The right fourth arm is hectocotylized and in five females, spermatophores were attached under the mantle, behind the nuchal cartilage
(Ishikawa, 1914).
It has been recorded in the stomachs of the Alaskan pollack (Shimomura and Fukataki, 1957).
3. ? Enoploteuthis dubia Adam 1960
This species is doubtfully referred to the genus and is only represented by a single male with 8 mantle length of 3.6 cm, taken at Eylath in
the Red Sea (Adam, 1960b).
4. Enoploteuthis galaxias Berry, 1918
Euoploteuthis gakzxias Cotton, 1942
This was taken off Victoria, Australia, with open nets fished at
200-460 m: a single male has a mantle length of 7.3 cm and three
females mantle lengths of 7.2, 7.8 and 8.7 cm.
