26 LOLIGINIDiE. 



LoLiOLUS, Steenstrnp, 1856. 



Distr. — 3 species ; Gulf of California, Indian Ocean. L. affinis, 

 Steenst. (xxv, 30). 



Body rather long, with posterior round fins united behind ; 

 siphon not attached to the head. Fourth left arm hectocotylized 

 in its entire length. Gladius feather-like, broad. Otherwise as 

 in Loligo. 



Loligo hemiptera, L. brevipinna, and other Loligines with 

 blunt extremity and round fins, ma}^ perhaps belong to this small 

 group, which is not widely separated by its characters from 

 Loligo. 



Sepioteuthis, Blainv., 1824. 



Syyi. — Chondrosepia, Leuck, 1826. 



Distr. — 14 species; West Indies, Cape, Red Sea, Java, Aus- 

 tralia, Mediterranean, Madagascar, Sandwich Islands. S. Steno- 

 dactyla^ Grant (xxv, 24). *S. lunulata, Fer. Orb. (xxv, 25). 



Body rather long or oval, with small lateral fins extending its 

 entire length ; siphon attached to the head by muscular bands ; 

 buccal skin with seven projections covered with suckers ; a strong 

 wrinkle behind the eyes. Fourth left arm hectocotylized at its 

 extremity. Otherwise like Loligo. 



Teuthopsis, Deslongchamps, 1835. 



Etym. — ■ TeuthiSy a calamary, and opsis, like. 



Distr. — A few species known, fossil in the lias of France and 

 Wurtemberg. T. Bunnellii, Desl. (xxviii, 55, 56). 



Pen or gladius dilated and spatulate behind, its wings curved 

 towards the ventral side somewhat spoon-like. 



Leptoteuthis, Meyer, 1834. 



Etym. — Leptos, thin, and teuthis, a calamary. 



Distr. — L. gigaSy Meyer (xxviii, 57). Oxford clay, Solenhofen. 



Shaft of the pen enlarging from a point to a broad blade in 

 front, with long, lateral wings starting from the posterior pointed 

 end. 



Belemnosepia, Agassiz, 1836. 



Syn. — Belopeltis,yoltz; Geoteuthis,Miinst.,1843; Loligosepia, 

 Queenst., 1839 ; Palseosepia, Theodori, 1844. 



Distr. — 9 sp. Fossil, in the Upper Lias of Wurtemburg, 

 Calvados and Lyme Regis. B. lata, Miinst. (xxviii, 63). 



Gladius like Leptoteuthis and perhaps not separable from it. 

 The shaft is more triangular, and the lateral wings broader, with 

 more rounded outlines. 



Besides the pens of this calamary, the ink-bag, mantle and 

 bases of the arms, as well as the horny shells, are preserved. 

 Some of the ink-bags are nearly a foot in length, and are invested
