L. NEGLECTA, Graj'. PI. 55, fig. 171. 



Body oblong, subcylindrical ; fins two-thirds the length of the 

 body, rhombic, rounded on the sides ; tentacular arms with eight 

 or nine ver}^ large cups in two i-ows, and small ones at the ends. 

 Shell lanceolate. A figure of L. vulgaria in Fer. and Orb. (t. 8, 

 f. 1,2) is cited for this species ; and also by Lafont in his de- 

 scription of L. Moulinsi. The latter author makes the cups of 

 the tentacles nearly equal in size^ but Gray more accurately 

 describes d'Orbigny's figure. 



Southern Europe, Atlantic and Mediterranean. 

 L. vuLGAEis, Lamarck. PI. 56, figs. 172-177. 



Body large, attenuated behind ; eyes large ; tins nearly three- 

 fourths the length of the body, rhomboidal, the angle well pro- 

 nounced ; third pair of arms dorsally webbed ; tentacular clubs 

 long, the middle suckers comparatively very large. 



Length, 8 or 10 inches. 



This is retained by most authors as the Lamarckian type in 

 the division of the species. 



Mediterranean ; S. Atlantic Coast of Europe. 



I figure the shell of the male, as well as the wider shell of the 

 female of this species in order to show the great difference of 

 form between them. 



L. FoRBESii, Steenstrup. PI. 56, fig. 178. 



Body much attenuated behind ; eyes small ; fins about two- 

 thirds the length of the body, with well-pronounced external 

 angles ; arms rather long ; clubs of tentacles short, with cups of 

 nearly equal size. 8 or 1 inches. 



This is the L. vulgaris of British authors. 



Seas of NortJiern Europe, Bay of Biscay, etc. 

 L. MACROPTHALMA, Lafout. PI. 56, fig. 179. 



Body attenuated behind ; eyes enormous, close together ; head 

 narrowed between the eyes and base of the arms; fins* two-thirds 

 the length of the body, angles well pronounced ; clubs short and 

 carrying nearly equal suckers. Length, 10 to 12 inches. Close 

 to L. vulgari.^, but differing by its tentacular cups of nearly 

 equal size. 



Bay of Biscay.
