 broad expansions, but the central shaft broader and not keeled. 



Indian Ocean. 

 L. STEENSTRUPI, Dall. 



Animal in general form much resembling L. typus ; arms very 

 short ; tentacles from two to three times the length of the arms, 

 lanceolate at the ends, with three rows of cupules. Color 

 yellowish-white, w r ith round spots and ocelli of various shades of

~ :: ~ Buccal membrane provided with cups. 



t Shell lanceolate, the wings thickened on the margins.* 



S. GUINENSIS, Quoy and Gaim. PL 61, figs. 198-200. 



Body oval, oblong ; fins very broad, fleshy, most dilated 

 behind the middle of the bodj^ ; sessile arms slender, elongate, 

 unequal, order of length 3, 2, 4, 1 ; cups depressed, oblique, 

 rings with strong, curved, distant teeth, longest on the highest 

 side ; tentacles with large, blunt clubs, the cups rather oblique, 

 in four rows, and the rings of the larger central ones narrow,

 dark round spots on the superior surface of the fins. 



S. AUSTRALIS, Quoy and Gaim. PL 61, figs. 201-205. 



Body oblong, cylindrical, truncated in front, acuminated and 

 blunt behind ; fins very broad, fleshy, subrhomboidal ; sessile

* I have some doubt whether either this character or the presence of 

 cups on the membrane is of specific value ; if it is not, several species 

 which I have separated by these differences must be united.
