 (Vera Cruz.) 



PI. 5, fig. 78: length 2.35 mm. (Tampico).

The figures represent an older (fig. 76) and a younger (fig. 

 77) shell, from Vera Cruz, the type locality. Also an old shell 

 ,(figs. 78, 79) from Tampico, representing the absolutely synony- 

 mous form I called C. jod. 



In recognizing the Mexican specimens as a race distinguish- 

 able from the Cuban form, I am probably placing too much 

 dependence upon a slight variation in microscopic sculpture. 

 I merely give the facts observed for what they may be worth. 



Var. minutissima (Guppy). PI. 4, fig. 68; pi. 5, figs. 80, 84. 

 "A very minute, glassy, hyaline, smooth, shining, fusiformly 

 cylindric, shell with 5 whorls, of which the last forms more 

 than half the length of the shell, spire short, with obtuse apex. 

 Aperture elongate-oval, narrow above, wide below; outer lip 

 simple; columella scarcely truncate, passing into a white callus 

 which connects the ends of the peristome. Length 2, diam .75 

 mm.'' (Guppy). 



Trinidad: Amongst dead leaves at Maraccas (Guppy, type 

 loc.). St. Vincent, in dry forest, leeward side, at 1000 ft. (H. 

 H. Smith). Barbados (L. B. Brown).
