226 HELIX. 



brown band or series of spots below; whorls 4-1, a little convex, reg- 

 ularly increasing, separated by regularly, moderately impressed 

 suture ; body-whorl slightly dilated, subplane above, convex below, 

 briefly deflexed anteriorly ; aperture oblique, ovate-rotund, slightly 

 lunate ; peristome a little reflexed, labiate within, the margins ap- 

 proximating, connected by a very thin brownish callus, the basal 

 margin at the insertion dilated, closing the umbilicus, in adults, 

 with a brownish callus. Diam. 20, alt. 10 mill. (Maltzan.')

H. CIOFALOI Cafici, 1885. 



This Sicilian species was described by Cafici in II Naturalista 

 Sidliano, 1885, p. 151. It is not figured, but is compared with H. 

 nbrcea (Bourg.) Mabille, a form which has not been, probably can- 

 not be, identified with certainty. Under these circumstances, and 

 in view of the extreme difficulty of distinguishing the species of 

 Iberus, even when figured, H. ciofaloi had better be Jeft in obscurity 

 until its claims to specific distinction are made more patent. 

 H. SILVESTRIT Cafici, is the name given to the form figured by 

 Kobelt (Iconographie, figs. 1848-1850) as a depressed variety of H. 

 nebrodensis. Figs. 53-56 of my plate 65 are copies of these fig- 

 ures of Kobelt. See II. Nat. Sicil., 1885, p. 152. Cafici gives no 

 diagnosis. 

 H. SUBSTRIGATA (Bourg.) Mabille, 1868. Sicily. 



Another unfigured Silician Iberus, probably a synonym of H. 

 strigata. 



H. ABROMTA (Bourg.) Mabille. Lombardy. 



H. AB^KA (Bourg.) Mabille. Lombardy. 



Have been identified by Kobelt with H. muralis.

Umbilicate, depressed, solid, dull above, brownish white lightei ' 

 below, with five indistinct light brown girdles composed of elongated 

 or arrow-shaped blotches; strongly, obliquely striate above, the base 

 smoother; spire very low conic, obtuse; whorls 4-i, rather rapidly 

 widening, the apical convex, smooth, save for a microscopic granula- 

 tion which is more or less visible all over the shell, the following
