Found in Florida, among small shells drifted in the sand. 



It has been detected in Cuba, Jamaica, and Porto Rico, and 

 has been introduced into England. 



Binney is the only American author who mentions its existence 

 in this country. He places it under Achatina. Gould, in Terr. 

 Moll., leaves it in that genus provisionally, mentioning the doubt 

 existing concerning it. 



Spurious Species of Auriculid^. 



Otina zonata, Pfeiffek. Vide Velutiiia zonata, p. 22. 



Family OTINID^. 



Lingual membrane, as in AuricuUdse, broad, teetli in nume- 

 rous cross series. Head large, broad, obtuse, moutli verti- 

 cally cloven, furnished with distinct jaws. Tentacles flattened, 

 eyes at the upper part of their base. 



Shell ear-shaped, colored ; columellar margin simple ; outer 

 lip simple and acute. 



Animal amphibious, living near the sea. 



The species of this small family differ from the Auriculidse in 

 having flattened tentacles, and from the Limnaeidae in having the 

 eyes on the upper part of the base of the tentacles, instead of at 

 the inner edge of the base, and in havin'a; colored shells.
