«* From the observations of Mr. W. T. Blanford, the animal of 7’. 
lychnia is without a mucous pore at the extremity of the foot; and 
Trochomorpha therefore must be removed from the family Stenopide. 
The species infula, Bens., however, hitherto included in Trocho- 
morpha, is, according to Mr. Blanford, furnished with one, and must 
remain in that family, where it may be considered the type of a 
group, under the name of Sitala.”—H. Ad.
