REVIEW OF THE SYSTEMATICS AND ECOLOGY OF OOEANIO SQUIDS

it has been recorded from the Gulf of Mexico (Voss, 1956b) but Adam
(1962) considers that this needs confirmation and from 11"s 14'E off
West Africa (Adam, 1962). Adam (1962) described some geographical
varieties.
It has been taken at the surface (Voss, 195613) and in an open net
fished to as much as 570 m (Morales, 1962).
During growth the arms remain about the same size relative to the
mantle length, the tentacles become relatively longer, the head relatively shorter, the body relatively narrower and the fin relatively longer
(Fig. 20, C). The largest specimen known to the author has a mantle
length of 20.0 cm (Joubin, 1894~). According to Risso (1854 after
Adam, 1942b) it inhabits gravel regions in spring and summer at
Nice and spawns in summer.
It has been taken from the stomach of a dolphin (Joubin, 1894c,
1900).
D . Chaunoteuthia
1. Chaunoteuthis mollis Appellof, 1890
A very rare species known from the Mediterranean (Appellof, 1890;
Grimpe, 1921a; Naef, 1923), the north east Atlantic (Lonnberg, 1896b;
Joubin, 1920) and off Lagos (Pfeffer, 1912). Several have been found
dead at the surface and a young one was taken at about 150 m (Naef,
1923). The specimens measure up to 17.15 cm in mantle length and
those which have been sexed (including the largest) are females.
Specimens described by Appellof, Lbnnberg, and Grimpe have a row
of spermatophores stuck into the mantle running back from the
mantle connectives on either side. A young specimen, 1.25 cm in
mantle length was described by Naef (1923).
E. Onychia
A large number of species have been referred to this genus but the
great majority should be synonymized with Onychia curribaea Lesueur,
1821. The few specimens which are possibly separable are insufficiently
known and will not be treated here. The genus may prove to be
monotypic when more specimens can be examined.
