MANUAL OF THE MOLLUSCA. 



FAMILY I. Strombid^. "Wing-sliells. 



SJiell \s\\k an expanded lip, deeply notched near the canal. Opercuhim 

 claw-shaped, serrated on the outer edge. 



Animal furnished with large eyes, placed on thick pedicels ; tentacles 

 slender, rising from the middle of the eye-pedicels. Foot narroAV, ill adapted 

 for creeping. Lingual teeth single ; uncini, thi-ee on each side. 



The stromhs are carrion feeders, and, for molluscous animals, very active ; 

 they progress by a sort of leaping movement, turning their heavy shell fr-om 

 side to side. Their eyes are more perfect than those of the other gasteropods, 

 or of many fishes.

t The lingual dentition of strombus resembles that of aporrhais, and is unlike that 

 of the whelks; but it is more probable that aporrhais is the representative of strom- 

 bus, than that it is very closely allied.
