LO LI GOP SIS. 163 



shorter than in L. pavo, being only twice the length of the ses- 

 sile arms. Not figured. 



North Greenland. 



L. PAVO, Lesneur. PI. 68, fig. 252 ; pi. 69, fig. 253. 



Body smooth, conical, elongated, spotted with red ; fins ter- 

 minal, short, soft, narrow, outline together heart-shaped, not 

 notched in front ; sessile arms short, slender, three upper pairs 

 rounded ; cups much depressed, broad, oblique, rings smooth ex- 

 teriorly, inner edge divided into square teeth ; tentacles slender, 

 very long. Shell elongate, very thin, nearly gelatinous, attenu- 

 ated anteriorly, lanceolate posteriorly. 



Total length, including tentacles, more than 3 feet. 



Arctic Seas to Madeira. 



The figure (which is a copy of Lesueur's) represents an indi- 

 vidual with mutilated arms. PI. 26 of the second edition of 

 Gould's " Invertebrata of Massachusetts," intended for this 

 species, probably represents Ommastrephes illecebrosa Lesueur. 



L. ELLIPSOPTERA, Adams. PI. 68. fig. 254. 



Body funnel-shaped, semipellucid ; hinder part elongate, taper- 

 ing ; fins depressed, semicircular, rounded, outline together ob- 

 long-; siphuncle very large; arms very unequal, comparative 

 length 2, 3, 1, 4. Shell slender, penniform. 



Length, including sessile arms, about (> inches. 



North Atlantic Ocean. 



A single specimen only discovered, which was in bad condition, 

 as the tentacles are neither figured nor described. Its distinct- 

 ness from L. cyclura is veiy questionable. 



L. CYCLURA, Lesueur. PL 09, fig. 225. 



Body coniform ; terminal fin orbicular ; head small, 03* es 

 large, prominent; arms unequal, order of length 3. 2. 1, 4. 

 Color bluish and red, with red spots, and remote transverse 

 abbreviated lines and dorsal spots of black. 



Total length, 5-J inches. 



Indian Ocean ; Pacific Ocean, Lai. 37 8., long. 33 E. 



D'Orbigny and Gray have placed with this species, L. guttata, 

 Grant, the body of which has rows of tubercles, but Lesueur 

 describes and figures a smooth species.
