224 HELIX. 



Var. OKTA Paulucci, PI. 65, figs. 69, 70. 



Larger, conic-globose ; whorls 5, rather convex, the last especially 

 inflated. Diam. 21, alt. 14 mill. 



H. SAXETANA Paulucci, 1886. PI 66, figs. 75-77. 



Subcovered perforate, subglobose-depressed, solid, shining, coarsely 

 and irregularly striate, flesh-colored, with four interrupted chestnut 

 bands ; apex minute, corneous, smooth ; whorls 5, slightly convex, 

 the inner regularly, the last rapidly widening, much inflated below 

 strongly descending anteriorly, separated by impressed sutures ; 

 aperture nearly circular ; peristome reflexed, pinkish brown sub- 

 labiate, margins approximating, the upper straight, the lower deep- 

 Iv arcuate, with a chestnut umbilical spot. Diam. 20, alt. 13 mill. 



Promontory of Argentaro, Italy. 



A small form, diam. 15, alt. 9, and a smaller, diam. 12, alt. 8 

 mill., are also noted by Mine. Paulucci. 



This species is most nearly allied to H. mariannve. It has one- 

 half of a whorl less than the latter species, is more depressed, the 

 last whorl is smaller and more inflated below, the mouth more cir- 

 cular, and the superior margin of the peristome is straight. From 

 If. carsoliana, var. milettiana which is also allied, the number of 

 whorls (lesser by one), the less elevated form, flatter whorls, larger, 

 rounder aperture etc., will separate saxetana. 



Unfigured and unidentified species of Iberus. 



H. THERESA (" Benoit") Martens, 1861. 



Narrowly umbilicate, depressed, obliquely rugose, whitish, with 

 four interrupted yellowish brown bands; whorls 4-] ; slightly con- 

 vex, the last descending ; aperture very oblique, ovate-rotund ; 

 peristome patulo-reflexed, sublabiate, the margins moderately con- 

 verging, columellar arcuate ; no umbilical spot, (von Martens.^) 



Diam. 18, alt, 8 mill. 



Sicily. 



May be a synonym of H. strigata. There is an H. teresce Benoit, 

 1845, but it is the same as H. flavida Ziegl. It is not unlikely that 

 some confusion of specimens caused von Martens to describe the 

 above Iberus as "H. therescf Benoit." 



H. UMBRICA (Charpentier) Mabille, 1868. 



Moderately umbilicated, orbiculate-depressed, above convex- 

 mamillate, whitish lutescent, a little shining, opaque, solid, orna- 

 mented with lamelliform costa?; spire subdepressed-subconvex, apex
