REVIEW OF THE SYSTEMATICS AND ECOLOQY OF OCEANI U
SQUIDS
223
specimen is 7-2 cm in mantle length (Allan, 1945). While the largest
male and another of 4-7 cm mantle length was reported as being
hectocotylized (Chun, 1910a; Sasaki, 1929a), the largest female has
small papilliform nidamental glands (Sasaki, 1929a).
3. Pyrgopsis lemur Berry, 1920
This is very close to, and may even be an Atlantic form of,
P. schneehageni (Pfeffer, 1884). It has been recorded from the western
North Atlantic from east of Cape Hatteras (Berry, 1920) and the
Caribbean region (Voss, 1958). It has been taken at the surface and
at 46 m depth. The largest specimen has a mantle length of 3.2 cm
(Berry, 1920).
4. Pyrgopsis rhynchopfiorus Rochebrune, 1884
Zygaenopsis zygaena Pfeffer, 1900
This is possibly the same species as P. paci$ca (Issel, 1908). It has
been recorded from Agulhas bank (Rochebrune, 1884) and St. Paul’s
island (Pfeffer, 1912). The mantle length of the type is 2.0 cm.
5. Pyrgopsis schneehageni (Pfeffer, 1884)
Loligopsis Schneehageni Pfeffer, 1884
Taonius schneehageni Hoyle, 1886a
This may be a form of P . paci$ca (Robson, 1924c) and has been
recorded from Chile (Pfeffer, 1884) and from 50 miles S.W. of Cape
Mala, Panama (Boone, 1933). Boone’s specimens were dredged from
550 m and included the largest known specimen with a mantle length
of 10-6 cm.
E. Leachia
The two species in this genus are probably distinct but not all the
synonyms listed for L. cyclura can definitely be excluded from being
L. eschscholtzi.

Loligopsis cyclurus FBrussac, 1832 after d’orbigny, 1835-1848
Loligo Leachii Blainville, 1823
Perothis pellucida Rathke, 1833
Loligopsis cyclura d’orbigny, 1835-1848
Leachia ellipsoptera Steenstrup, 1861
This species (Fig. 48) has been recorded from the North Atlantic
(Steenstrup, 1861a; Lonnberg, 1896b; Joubin, 1905b, 1920; Pfeffer,
1912; Chun, 1913; Rees and Maul, 1956; Voss, 1960a), off South Africa
