2. Sandalops melancholicus Chun, 1906
Hensenioteuthis rnelancholicus Massy, 1925
This is only known from a specimen taken to the north east of
Tristan da Cunha a t 32"8'S 8"28'W with a vertical net fished from
1000 m. It has a mantle length of 1.15 cm.
3. Sandalops pathopsis Berry, 1920
The type is the only specimen described and was taken in the
North Atlantic a t 32"33'N 72'14'W with an open net fished to 1 100 m.
Its dorsal mantle length is 0.8 cm. This is probably an earlier stage
of the species named S. ecthambus.
J. Corynomrna
This genus contains a single species of small specimens with early
larval features (Fig. 49) but mainly differing from Sandalops species
in having a photophore on the liver.
1. Corynomma speculator Chun, 1906
Cranchiidarum Chun, 1903
Liguriellu podophthalma Issel, 1908
Specimens referred to this species have been recorded from the
North Atlantic (Chun, 1906, 1910a, 1913), the Mediterranean (Joubin,
1924), the South Atlantic (Issel, 1908), the Indian Ocean (Chun, 1906,
1910a) and the species has been listed for South Africa (Massy, 1925).
Although a young specimen was taken a t the surface (Chun, 1913) all
other specimens were taken in open nets fished deeper than 600 m,
and three in open nets fished to 2 000 m and over (Chun, 1906, Joubin,
1924). The largest specimen has a mantle length of 3.2 cm (Chun, 1906).
Voss (1960a) considered that this might possibly be the juvenile of
Phasmatopsis oceanica.
K. Bathothauma
Although the specimens of this genus grow to quite a large size and
possibly reach maturity they retain many larval features (Fig. 49).
1. Bathothuma lyromma Chun, 1906
A widely distributed species, this has been recorded from the
North Atlantic (Chun, 1913; Joubin, 1920; Thiele, 1921; Beebe, 1930
photo only; Desbrosses, 1938; Voss, 1960a), the Philippines (Voss,
1963a), Tasmania (Allan, 1940, 1945) and from the Eastern Pacific
(Hoyle, 1909b). A small specimen has been taken near the surface
