figure here given is inteuded to show the shape of the individnal teeth 

 of G. truncata from the central to the extreme marginal. 



I have not h^id an opportunity of examining the lingual membrane 

 of G. hullata, Te.vasiana, decussata, or Vannxemensis. 



The restricted subgenus is confined almost exclusively to Mexico 

 and Central America, but several species are found in our Sonthern 

 Eegion, even as far north as North Carolina. There is also one Medi- 

 terranean species. 



Cilaiidiiia Vaiiuxoniensis, Lea. 



Shell elongated, ovate-fusiform, thin and fragile, considerably trans- 

 parent, pale fawn-color, in scnne specimens in- fig.376. 

 clined to greenish, and generally flecked with 

 distant, pale spots ; the surface is, in a measure^ 

 coarsely granulated by the decussation of longi- 

 tudinal 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 whorl : whorls 7 or 8, 

 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 enamel. Length 

 of axis, 68'""'; breadth, 25'"'".
