1 500 m and 1266 m. The largest has a mantle length of 4.8 cm (Dell,
19598).
B. Cirrobrachium
1. Cirrobrachium danae Joubin, 1933
Known only from the type taken in the North Atlantic at 12'59"
32'49'W (Joubin, 1933) it was taken a t a depth of 25 m a t night. Its
mantle length is 1.6 cm.
2. Cirrobrachium Jiliferum Hoyle, 1904b
The type which has no body was caught in the eastern Pacific
0'50'N 137'54'W (Hoyle, 1904b) and a specimen from the Indian
Ocean taken at 25'5 57'7'E was referred to this species by Thiele
(1921). The type was taken in an open trawl a t 4 560 m while the other
specimen was taken a t 20 m (Thiele, 1921). The complete specimen
is very small having a mantle length of 0.7 cm but it is recognizable
as a young male.
X. PHOLIDOTEUTHIDAE
A. Pholidoteuthis
1. Pholidoteuthis adami Voss, 1956b
This species has been recorded in the upper Gulf of Mexico between
the surface and 867 m (Voss, 1956b). Schools appear on the surface
several hours after sunset and sometimes " a school would swim past
the ship for several hours '' (Mr. Springer's observations reported by
Vow, 1956b). Voss (1956b) suggested that the species may be an
important food of the Sperm whales which are very numerous in the
middle part of the Gulf. Specimens with a mantle length of 30.5 cm are
known.
2. Pholidoteuthis boschmai Adam, 1950b
Only known from a single female taken at 5'58's 121'32'E in the
Pacific, which was caught in a vertical net between 2 000 m and the
surface and has a mantle length of 27.3 cm.
