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. VILL^E (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: near Palermo, extremely rare. (Ccecilianella villa: 

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



Perhaps related to H. alleryi Cafici. 



16. H. ALLERYI (Cafici). PI. 51, figs. 16, 17. 



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
