Teleoteuthis compacta Berry 1913. (PI. lii, fig. 4, 5) 



Teleoteuthis appellofi Berry 1909, p. 419 (locality record only), not of Pfeffer 1900. 

 Teleoteuthis compacta Berry igi3, p. 565. 



Animal small, loliginiform. Mantle almost cylindrical anteriorly; slightly swollen a little in 

 advance of the middle, thence tapering rapidly to a very acute point. Fins enormous, broadly sagit- 

 tate in outline, their total width about equal to the length of the mantle; length a little more than 



half that of the mantle. Mantle margin slightly 

 produced in the medio-dorsal line to form an 

 obtuse point, and a little more prominently in 

 the same way on either side of the funnel; emar- 

 ginate below the funnel. 



Head squarish, narrower than the mantle, 

 into which it may be almost completely with- 

 drawn. Eyes little prominent; their lid openings 

 small, notched in front. 



Arms short, stout, little attenuate; unequal, 

 their order of length 3, 2, 4, 1; the dorsal arms 

 clearly shorter than those of the second and third 

 pairs. Suckers on all the arms small, rotund, 

 closely ranked in two widely interspaced series. 

 (PI. m, fig. 5). Umbrella wanting, but all the arms 

 well angled, and the third pair furnished exter- 

 nally with a strong membranous keel. 



Tentacles short, stout, but little exceeding 

 the arms; clubs not thickened, but broadly keeled 

 above and slightly so along the ventral margin; 

 both suckers and hooks present on the club; hooks 

 sessile, 10 to n in number and in a single longi- 

 tudinal series, comprising the more ventral of the 

 two median rows of acetabula; first five hooks 

 quite small, the next three much larger, the distal 

 ones diminishing again; the two dorsal rows of 

 suckers irregular, the first five pairs small and 

 closely placed, the succeeding ones slightly larger and more distant, becoming smaller again distally ; 

 the suckers of the inner dorsal row persist in alternation with the hooks to the tip of the club, but the 

 marginal row becomes obsolete distally and comprises only about eight suckers in all ; suckers of the 

 ventral row exceedingly minute, especially distally where they are placed very far apart. The extreme 

 tip of the tentacle is occupied by a group of excessively minute suckers, which are scarcely visible as 

 such with an ordinary hand lens. Fixing apparatus well developed, comprising a quadruple series of 

 small suckers and pads in alternation; about 8 pads and 12 suckers can be made out. (PI. lii, fig. 4.) 

 Gladius delicate, the expanded wings greatly narrowing in front of the hollow terminal cone. 

 Color in alcohol a brownish buff. Chromatophores light brown, scarcely visible below.
