(Fage, 1941) and off Sierra Leone (Illig, 1930); and from the South Atlantic, west of Cape Town 

 (Tattersall, 1925), and south of Gough Island (Tattersall, 1913). It has been recorded from the north- 

 west of the Indian Ocean (Tattersall, 1939) and from the south of the Indian Ocean between Kerguelen 

 and South-West Australia (G. O. Sars, 1885 a). In the Pacific it has been taken as far north as the 

 Behring Sea and off the coasts of British Columbia and the west coast of the United States (Ortmann, 

 1906; W. M. Tattersall, 1951), from the Gulf of Panama (Fage, 1941), the Hawaiian Isles (Ortmann, 

 1906; W. M. Tattersall, 1951), from Japan (W. M. Tattersall, 1951) and from many places in the 

 China Sea, the Philippines, New Hebrides, New Caledonia and New Zealand (Fage, 1941).

This species was taken by ' Discovery ' and ' Discovery II ' at eighteen stations of which sixteen were 

 situated in the South Atlantic between latitudes 33 S. and 6o° S., extending from the west of Cape 

 Town in the east to the Falkland Is. and South Georgia in the west. A single immature specimen 

 was captured at station 1755 in the central Indian Ocean and four immature specimens at station 

 1298 in the Bellingshausen Sea in latitude 69 16' S. This is the most southerly record yet made 

 of the species. 



G. gigas has usually been taken singly or in very small numbers and consequently, in spite of the 

 many records of its capture, few specimens have been collected. Of these only very few have been 

 adults. The type, 142 mm. in length, was an adult male and Tattersall (1913, p. 868) recorded 

 a female, presumably adult, of 160 mm. from the South Atlantic. Ortmann (1906, p. 36) recorded 

 a female of 1 19 mm. from the coast of Alaska, stating that it had a fully developed marsupium, while
