REVIEW OF THE SYSTEMATICS AND ECOLOGY OF OCEANIC SQUIDS
203
All records are from the North Atlantic (Fig. 40), from off Nova Scotia
(Verrill, 1881c; Joubin, 1924), the Gulf of Mexico (Voss, 1956b) and
the central Atlantic (Joubin, 1933). It has been taken with open nets
from 520 m (Voss, 1956b) to over 4 000 m (Johnson, 1934). The largest
had a mantle length of 57.0 cm.
The long narrow tentacles each bear a well developed light organ
at their tip and it seems possible that these act as a lure for prey which
can then be arrested by the tentacular suckers and pulled in on the
“ line ” (Voss, 1956b).
5. Chiroteuthis macrosoma Goodrich, 1896
This should possibly be regarded as a synonym of C. picteti Joubin,
1894a (Voss, 1963a). Known only from the type, the species was
taken at 12’50’N 81’30‘E in the Indian Ocean a t a depth of 870 m.
The mantle length is 38.5 cm and it is female.
6. Chiroteuthis picteti Joubin, 1894a
Joubin (1924) regarded both C. macrosoma Goodrich, 1896 and
C. imperator Chun, 1910 as synonyms of this species and the question
has not yet been resolved (Voss, 1963a). The types were described
from Amboine (Joubin, 1894a) and further specimens were recovered
from the North Atlantic (Joubin, 1924) (Fig. 40). It has been taken
in open nets fished to 4 300 m. The largest has a mantle length (to
the back of the fins) of 23.5 cm.
7. Chiroteuthis portieri Joubin, 1912
Only known from the type specimen which was taken at 29’03”
16’08’W near the Canary Islands in an open net fished to 3 600 m
(Joubin, 1912, 1916). It has a mantle length of 6.7 cm.
8. Chiroteuthis veranyi (FBrussac, 1835)
Loligopsis Veranyi Fkruaaac, 1835
Loligopsis vermicolaris Ruppell, 1844
Loligopsis vermicularis Vkrany, 1851
Onychoteuthis perlatus Riaso, 1854
Loligopsis perlatus Risso, 1854
Doratopsis vermicularis Rochebrune, 1884
Hyaloteuthis vermicularis Pfeffer, 1884
The adult form has been taken in the eastern Mediterranean (Degner,
1925; Hoenigman, 1958) (Fig. 37), the western Mediterranean (FBrussac,
1836; d’orbigny, 1845; VBrany, 1861; Risso, 1854; Aucapitaine, 1863;
Targioni-Tozzetti, 1869a; Carus, 1890; Ficalbi, 1899; Joubin, 1893b,
