Soicthern Europe. 



This animal sometiuies attains much greater dimensions than 

 the usual length given above. Specimens weighing over thirty 

 pounds are occasionally captured. The flesh is hai-d, coriaceous 

 and unwholesome, and is but little used, the sale of it being pro- 

 hibited in the market of Nice. At flenoa it is called Caama. 

 in Sardinia. Calamari or Todari. in Sicily. Todaru. etc. 



t t Third pair of arms with a narroio fleshy fin, siipported by cross ribs on 

 the inner edge of the ventral side; second pair of arms 

 without tubercles on the edge.

Body elongate, cylindrical, violet-colored ; fins broad, oc- 

 cupying half the length, nicked in front, together transversely 

 rhomboidal, acute; arms with oblique, equal-sized cups, their 

 rings with acute teeth on the higher side, and smooth on the 

 lower one ; tentacles naked one-third their length, the cups in 

 two series, then in four, the tip compressed with a narrow, trian- 

 gular patch of a few small cups in three or four series at the 

 base, and two series at the end. The shell is very long, its cone 

 proportionally much shorter than in the other species. 



Total length, 3-5 feet ; length of body, 1-6 feet. 



Pacific Ocean, W. of South America. ? S. Clemente Is., Gal. 



O. PTEROPUS, Steensti'up. 



Animal very like 0. gigas, and even larger in size ; attaining 

 nearly 6 feet in length. The first pair of arms shortest, being 

 a foot long, the others 15 to 16 inches ; the tentacles 32 inches. 

 Mediterranean (Marseilles) ; Atlantic Ocean. 



I have not seen any figure of this species : it may = 0. gigas, 

 or even include the large specimens of 0. todarus.
