REVIEW OF THE SYSTEMATICS AND ECOLOGY OF OCEANIC SQUIDS

C . Liocranchia
The species of this genus form a regular part of catches made with
larger nets fished in the upper levels of the sea. They are clearly
characterized by two V-shaped lines of tubercles with the apex of the
V near the fusions between funnel and mantle. Lamberg (1896b)
showed that young specimens are globular and become elongated
later in life. Two globose forms, L. gardineri Robson (1921) and
L. globulus Berry (1909a), have been named as separate species and
whereas the former has peculiarly thickened tentacle stalks which
distinguish it from other forms, the latter will be considered under
L. reinhardti here from which it cannot be readily distinguished.
Voss (1963a) has pointed out considerable discrepancies between the
descriptions of L. reinhardti by various authors and the examination
of specimens from a wide area will be necessary to sort them out.
1. Liocranchia gardineri Robson, 1921
Known only from the type specimen this species was found off
Desroches atoll (Robson, 1921). It was caught in an open net fished to
about 370 m and measures 1.0 cm from the mantle apex to the base
of the arms and is probably larval. The curious tentacular stalks
could result from regeneration after damage.
2. Liocranchia intermedia Robson, 1924
This species is known only from the type which is probably a
male of L. reinhardti (Steenstrup, 1856), to judge from descriptions by
Robson (1924~) and Voss (1962e). It was recorded from Natal, South
Africa, and was taken with an open net fished at 475 m. The mantle
length is about 10.7 cm.
3. Liocranchia reinhardti (Steenstrup, 1856)
Leachia Reinhardti Steenstrup, 1856
Cranehia Reinhardti Steenstrup, 1861
Loligopsis (Perotis) Reinhardti Tryon, 1879
Perotw Reinhardti Rochebrune, 1884
Liocranchia Brockii Pfeffer, 1884
Cranchia Brockii Joubin, 1894a
Cranchia (Liocranchia) globula Berry, 1909a
A species recorded from the North Atlantic (Steenstrup, 1856;
Hoyle, 1886a; Lbnnberg, 1896b; Issel, 1908; Chun, 1910a; Pfeffer, 1912;
Bouxin and Legendre, 1936; Voss, 1955, 1958) (Fig. 47), the South
Atlantic (Chun, 1910a; Pfeffer, 1912; Robson, 1924; Adam, 1961),
