BRUUN 



which were first described by Johannes Schmidt (1922). Eventually it 

 died from the heat produced by the powerful light used by the photog- 

 rapher. 



Since my report of 1943 was published, two more specimens have 

 been found in the Dana collections: Dana Station 3946 I (3°26' S., 

 42°58'E.); 2 meters stramin-net, 600 meters wire; ventral mantle 

 length 3.4 mm, a very young specimen, with only 4 chambers in the 

 shell. Dana Station 4010 III (27°19' N., 16°4r W.) ; 2 meters stramin- 

 net, 300 meters wire; ventral mantle length 19 mm, immature. Another 

 specimen had been found previously in this same haul and included in 

 the report of 1943. 



3. SIZE, SEX, SHELL 



Since 26 specimens from one haul are so many more than from any 

 previous single catch, some details are here recorded for comparison with 

 earlier obsen'ations (Plate 1). 



All the females have well-developed ovaries. The eggs are probably 

 near mature size, about 1 mm in diameter. The males have fully devel- 

 oped hectocotyli, the smaller specimen with six, the larger one with seven 

 finger-like projections on the left hectocotylized arm. 



The sizes are just as would be expected in mature animals, much the 

 same as in earlier Indian Ocean records. The shell has been measured 

 across the dorso-ventral diameter, related to the ventral mantle length, 

 and expressed in percentages in Table 2. The females have been tabulated 

 with Atlantic specimens, and no important differences are noted.
