C/ECILIOIDES OF ITALY, SICILY, MALTA. 27 



Spire conic-turrite, the apex rather obtuse. Suture somewhat 

 impressed, margined. Whorls 6, convex, the last subovate, 

 tapering at the base, longer than the spire. Columella sub- 

 vertical, calloused, obliquely truncate, not reaching to the base. 

 Aperture ovate-lanceolate; peristome simple, unexpanded, the 

 margins joined by a rather thick callus, right margin arching 

 forward. Length 6, diam. 2, aperture 2.6x1 mm. (Ben.}

18. C. INNOVATA Gregorio. 



Shell very small, thin, translucent, fusiform-submitriform, 

 narrow. Spire short, composed of 3 whorls; last whorl rela- 

 tively very large, the aperture equal to the spire in length, in 

 this respect differing from C. tiberiana Ben. (Gregorio).

Numerous Sicilian forms have also been "described," as 

 follows. 



C. spadaforensis (Benoit). Shell somewhat solid, fusiform, 

 lucid, smooth, whitish; spire of 6 slightly convex whorls, sep- 

 arated by a superficial suture, which with strong magnification 

 is seen to be encircled with a band; apex very obtuse. Last 

 two whorls more than two-thirds the total length. Columella 

 twisted, but hardly truncate. Aperture narrow, long, acutely 

 angular above; peristome simple, acute, the margins joined by 

 a weak callus. Length 7.5, diam. 3 mm. Spadafora, near 

 Messina, Sicily (Cadi, ., BENOIT, Catalogo, 1881, p. 91).
