lodged in the liver, and the glands of the oviducts are very large. 

 The coalescing eggs are deposited in narrow garlands, and in two 

 rows. 



They are now subdivided according to the number and armature 

 of the feet and the form of the fins. 



LOLIGOPSIS, Lam. 



Or the Calmarets, should have but eight feet as in Octopus ; they 

 are only known, however, by drawings of but little authority*. 



In the true Loligo the long arms are furnished with cups like the 

 other tentacula, and the fins are placed near the point of the sac. 

 Three species are found in the European seas. 



L.vulgaris; Sepia loligo, L. ; Rondel., 506; Salv. 169. The 

 common Calmar. Fins forming a rhomb at the bottom of 

 the sac. 



L. sagittata, Lam. ; Seb., Ill, iv. The great Calmar. Fins 

 forming a triangle at the bottom of the sac ; arms shorter than 

 the body, and loaded with cups for about half their length. 



L. Media; Sep. media, L. ; Rondel, 508. The little Calmar. 

 Fins forming an ellipsis at the bottom of the sac, which termi- 

 nate in a sharp pointf . 



ONYKIA, Lesueur. ONYCHOTHEUTHIS, Lichtenst. 



Have the long arms furnished with cups terminating in hooks ; 

 in other respects the form is the samej. 



SEPIOLA, Cuv. 



Have the rounded fins attached to the sides of the sac and not to its 

 point. One species, 



S.vulgaris; S. sepiola, L. ; Rondel., 519, inhabits European 

 seas. The sac is short and obtuse, and the fins small and cir- 

 cular. It seldom exceeds three inches in length, and its horny 

 lamina is as slender and sharp as a stilet. 



CHONDROSEPIA, Leukard. SEPIOTHEUTES, Blainv. 



The whole margin of the sac, on each side, bordered with the fins, 

 as in Sepia ; but the shell horny, as in Loligo.
