706 LÖNNBERG, TWO CEPHALOPODS FROM TENERIFFE. 



O. megapterus (Verrill) Stp. 



brachial formula 3, 4 = 2, 1 



connective apparatus 4 — 4 



? O. eblance (Ball.) Gray. 

 »lateral arms lonsest». 



O. gouldi McCoY (Prodr. Zool. Victoria, decade 17, 1888). 



brachial forraula 2 = 3, 1 = 4 



fins small, their length 2\ in pallial length. 



Ohs.l Most probably a species of Illex, as uothing is either 

 said or pictured of a connective apparatus or of any folds or 

 pockets in the siphonal fossa! 



The other specimens of Cephalopods in the same collec- 

 tion are: 



1 Sepia hierred da Rang. 



1 Loligo vulgaris Lamarck. 



2 Octopus vulgaris Lamarck. 



1 » macropus RiSSO. 



2 » tuberculatus Blåinville. 



As the Ommatostrephes are pelagic in their habits, this 

 variety is probably to be found in other parts of the Atlantic, 

 but Sepia verrucosa is possibly confined to the West-African 

 region. It is stränge that in such a small collection two hitherto 

 unobserved forms should be found, the more so as they were col- 

 lected in a place so frequently visited by naturalists; it shows 

 how incomplete our present knowledge of the Cephalopods is. 

 This is especially the case with the pelagic forms, of which pro- 

 bably not half the numbér are known, not eveu from the At- 

 lantic. Every little addition to this chapter of zoology is there- 

 fore of interest.
