3. Mastigoteuthis dentata Hoyle, 1904b
This was thought to be a synonym of M . grimuldii Fischer and
Joubin, 1907 by Joubin (1924) but this opinion is not beyond dispute.
It has only been recorded from the Galapagos Islands and the Gulf of
Panama (Hoyle, 1904b) where it was caught with open nets fished to
930 m and 2 400 m. A female had a mantle length of 14.0 cm and a
male 7.2 cm.
4. Mastigoteuthis jlammea Chun, 1908
A rare, but widely distributed species (Fig. 42), this has been
recorded from the North Atlantic (Chun, 1908, 1910a, 1913) and from
New Zealand waters (Dell, 195913). It has been taken with open nets
fished to a minimum of 820 m and a maximum of 2 500 m.
The largest specimen had a mantle length of 4.8 cm. Chun (1913)
described a form which was possibly a larva of this species.
5 . Mastigoteuthis glaucopsis Chun, 1908
This rare species has been recorded in the Indian Ocean (Chun,
1908), the North Atlantic (Joubin, 1933) and has been listed for S .
Africa (Massy, 1925). Joubin (1933) used the varietal name athntica
for his specimen. The specimens were taken with open nets fished to
1213 m and 2 680 m. The largest had a mantle length of 11.2 cm
(Joubin, 1933).
6. Mastigoteuthis grimaldii (Joubin, 1895)
Chiroteuthis grimaldii Joubin, 1895b
Chiroteuthopsis Grimaldii Joubin, 1900
Nmtigoteuthis dentata Hoyle, 1904b
Joubin (1924) recorded more specimens than any other worker but
he considered M . dentata Hoyle, 1904 and M.$arnmea Chun, 1908 to be
synonyms of this species, a view which is not indisputable a t present.
All but one of the specimens were from the North Atlantic (Joubin,
1896b, 1924; Fischer and Joubin, 1907; Chun, 1910a, 1913; Adam,
1960c) (Fig. 42). The exception was a very doubtful record of a larva
from 42'40'5 148'16'E, off south-west Australia (Allan, 1945). It has
been taken in open nets fished t o a minimum of 600-800 m (Adam,
1960c) and a maximum of 5 100 m (Joubin, 1924). The two largest
known to the author have mantle lengths of 7.4 cm (Chun, 1913) and
7.8 cm (Joubin, 1924).
