43. Ennea turricula, Blf. P. Z. S. 1899, p. 768, pi. 50, figs. 16, 17. 



Distinguished from E. macrodon by having slightly coarser and 

 less close filiform costulation, only six whorls, and by the plaits 

 inside the mouth being much less developed. In adult shells 

 only the parietal plait remains conspicuous, but there are deep- 

 seated basal and columellar lamellae : in younger specimens «ith 

 the peristome thickened and expanded a small basal tubercle also 

 occurs. The transverse basal lamella of E. macrodon is wanting, 

 and the parietal plait is simple.

44. Ennea exilis, Blf. J. A. S B. xlix, 1880, p. 207, pi. 2, fig. 14 (lower 



fig. ; all the teeth are wrongly represented). 



Similar to E. macrodon, but much more slender and entirely 

 smooth, thin, and translucent, AVhorls 61^-7. The teeth are 

 smaller, the parietal lamella bears two knobs, but is not bifid ; 

 the basal plait is represented by two tubercular teeth united at 

 the base and running obliquely into the shell ; the only internal 

 plait is columellar rather than basal, and not directly behind 

 the basal tooth ; the columellar and dextral teeth are simply 

 tubercular.

Shell turreted, ver)^ slightly diminishing above, whitish horny ; 

 upper whorls smooth, last two with very fine hair-like costu- 

 lation ; apex obtuse ; whorls 7, slightly convex, the last com- 

 pressed at the base ; aperture roundly semioval ; peristome white, 

 expanded, margins joined by a thick callus, which is deeply in- 

 dented above at the place where it bears a parietal lamella running 

 into the whorl, there is also a columellar plait running obliquely 

 inwards and commencing inside the mouth ; no teeth in the 

 basal or dextral margins. 



Length 10, breadth 2^, height of aperture 2 mm.

This differs from E. pirriei chiefly in being coarsely ornamented 

 with vertical slightly flexuous ribbing throughout except on the 

 first two whorls. The callus that unites the margins of the 

 peristome is not indented above the parietal lamella which is near
