84 TERRESTRIAL AIR-BREATHING MOLLUSKS. 



A species of the Mexican fauna, but actually found also in the Texas Region. 

 I have not seen any other specimen than the one figured in Vol. III. 

 Animal and dentition unknown. 



Glandina truncata, GMELIN. 



Vol. III. Pis. LIX., LX., LXL, Fig. 2 ; LXIL, Fig. 2. 



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 longitudi- 

 nal, raised, and rounded striae ; whorls 6 or 7, moderately convex, the last 

 constituting three fourths the length of the shell, sbmewhat 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 as broad, narrow, 

 ovate-lunate, acute posteriorly, obtusely rounded anteriorly ; peristome nearly 

 rectilinear at its middle portion, and springing somewhat forwards ; columella 

 arched at its lower portion, and decidedly truncate at base ; throat salmon- 

 colored ; edge of peristome pale. Average length, 37 mill., often very much 

 longer, even 1 00 mill. ; breadth somewhat more than one third the length.
