HELIX. 251 



An attractive species, which may be distinguished from the pre- 

 ceding by the small apex. The pallid coloration, light, decussated 

 shell, sometimes partly denuded of the very thin cuticle, are the 

 more prominent characters. 



The peristome is very narrowly expanded except at its insertion 

 in all the specimens I have seen ; but a form figured by Kobelt (pi. 

 (5S. fig. 21,) shows a considerable departure from the type in this 

 respect. 

 H. NORDMANNI Parrevss, 1859. PI. 57, figs. 16-18. 



Covered or nearly covered perforate, depressed-globose, rather 

 solid, shining, yellowish white or greenish yellow, encircled by five 

 rather narrow deep brown hands, the second band narrowest ; finely 

 obliquely striate ; spire depressed conic, excentric, apex polished, 

 blunt ; suture well impressed; whorls 4-4 -i, convex, regularly and 

 moderately increasing, the last rapidly widening, very wide at the 

 aperture, decidedly indented at the umbilical region, descending an- 

 teriorly ; aperture oblique, slightly contracted, whitish, banded with 

 dark within; peristome white or flesh-tinted, slightly thickened 

 within, margins converging slightly, joined by a thin whitish callus, 

 outer lip simple, columellar margin strongly arcuate, with a triangu- 

 lar dilation -over the rather wide umbilicus, almost concealing it. 



Diain. 25-28, alt. 28-26 mill. 



Armenia ; Imeretia. 



May be known by the depressed form, rapid widening of the last 

 whorl toward the aperture, and the umbilicus, which is quite wide 

 for a Pomatin. 



II. KADDHT Hoettger. Unfigured. 



A species grouping with obtusaUs,nordmanni, christophi, maltzani; 

 most allied to H. obtwtati* [If. rulgaris] but larger, bright white, 

 five fasciate; spire more conic, whorls more convex, separated by 

 deeper sutures ; aperture more oblique, larger ; peristome more ex- 

 panded, rosaceous, not brown, the basal margin broad, plane, reflex- 

 Id. Diain. 8*, alt. 34 mill. 



The large apex and coloration are like obtusalis, but the convex 

 whorls, conic spire and rosy peritreme, which is reflexed and widen- 

 ed below, will serve to separate the species.
