336 HOHENWARTIANA. 



whitish and wide. The outer lip arches far forward, in pro- 

 file view, the greatest convexity being below the middle. It 

 is extremely similar to H. bourguignatiana, but differs by the 

 smaller size and less swollen basal portion. 



15. H. VILLAS (Benoit). 



A fine and elegant little shell resembling a Cionella in form. 

 It is obese, fusiform, lucid, diaphanous, smooth, transparent, 

 very obtuse at the end. Whorls 5, rather convex, suture su- 

 perficial, accompanied by a line. Last whorl one-third the 

 total length. Aperture rounded at the base, acutely angu- 

 lar above; peristome simple, acute, the margins joined by a 

 callus visible under the lens. Columella scarcely truncate. 

 Sicily: n'ear Palermo, extremely rare. (C&tilianella villa 

 BEN., Catalogo, 1881, p. 89). 



Perhaps related to E. alleryi Cafici.

Shell oblong-subventricose, very minute, very fragile, dia- 

 phanous, very glossy, pale corneous-buff ; spire short, the apex 

 obtuse as though mamillate. Whorls 5, slightly convex, all 

 to the fifth slowly increasing, the fifth increasing extremely 

 rapidly; suture well impressed and duplicate. Last whorl 

 almost exceeding three-fourths the total length. Aperture 

 oblong, angular above ; columella subvertical, not reaching the 

 base, subtruncate; peristome unexpanded, acute, the outer 

 margin arcuate, margins joined by a thin callus. Length 

 3.75, diam. 1.5, length of aperture 2.5 mm. (Cafici). 



Sicily: Abita Nociforo near Vizzini.

 pi. 10, f . la, 2a, June, 1882. 



A shorter, more compact form than other Sicilian species, 

 if it is a mature shell. 



17. H. NAUTICA (Westerlund). 



Shell fusiform turrite, with long, rapidly tapering spire. 

 Whorls 6 l /2 to 7, very weakly convex, rapidly and regularly 

 increasing, the last somewhat more than one-third the total
