papillffi above and three on each side ; lingual organ semioval, 

 armed with oblique ranges of recurved hooks. Genital orifice 

 at some distance behind the right eye-peduncle. Carnivorous,

Glandiiia Taniixemensis, Lea.— Shell elongated, ovate-fnsi- 

 form, thin and fragile, considerably transparent, pale fawn color, in some 

 specimens inclined to greenish, and generally 

 flecked with distant, pale spots ; the surface 

 is, in a measure, coarsely granulated by the 

 decussation of longitudinal and revolving 

 lines, the latter of which are more distant 

 from each other than the former, and become 

 less and less distinct towards the anterior 

 portion of the whirl ; whirls seven or eight, 

 the apical ones smooth and forming a mam- 

 millary tip ; suture crenulated ; aperture 

 about one-half the length of the shell, nearly 

 three times as long as broad ; columella 

 strongly arched, and scarcely glazed by en- 

 amel. Length of axis (JS, breadth 25 mill.

Glandina truncata, Gmelin. — Shell strong, ovate-fusiform or 

 ellipsoidal, obtuse at tip, of a pale ashy fawn color, or rather alternately 

 striped with ash color and fawn color, and more or less tinted rose color, 

 the surface shining and delicately fluted with longitudinal, raised, and 

 rounded strire ; whirls six or seven, moderately convex, the last consti- 

 tuting three-fourths the length of the shell, somewhat compressed at the 

 middle, so as to become in a measure cylindrical, narrowing forward and 

 rounded at base ; suture strongly marked, delicately crenulate ; aperture 

 about one-half the length of the shell, often more, and twice as long aa
