placed on a peduncle as long as the tentacle, and the 

 peduncles and tentacula are soldered together." 



Mr. Berkeley, in his description of the animal (ZooL 

 Journ. v. 429.), observes, " The most remarkable 

 circumstance in this animal is the position of the eyes 

 at the tip of the tentacle, as in Helix and its allies, 

 and not at the base. It would appear as if there 

 were in reality no tentacula, and only the tubercle, 

 common to many Mollusca, at the base of the tenta- 

 cula, a little more developed than usual." I am in- 

 clined to retain my former theory; for if the pedicel 

 of the eye of this genus is minutely examined, it will 

 appear to be formed of two parts united by a suture. 



A shell which I described from India, under the name 

 of Turbo Francesia (Wood, Supp. t. 6. f. 28.), has been 

 found by Mr. Benson to have the same kind of animal, 

 and to be a second species of the genus.
