HELIX. 229 



striate, whorls but little elevated, but convex ; apex flat, minutely 

 rugose ; whorls 4 or slightly more, much more rapidly increasing 

 and more convex than in typical guttata, the last quite rounded, and 

 very rapidly widening ; aperture very oblique, more circular than 

 in guttata, its margins converging, but not joined by a callus ; peri- 

 stome expanded, not thickened within, white ; its columellar margin 

 arcuate, slightly thickened, expanded over the umbilicus.

Described as H. dschulfensii. H. djulfensis Mouss. is the same. 

 There are in this species, as in H. guttata, fine impressed spiral lines 

 below the suture ; these are, however, sometimes almost obsolete- 

 The figures on pi. 55, (copied from v. Martens), are broader and 

 more depressed than the specimens I have seen which are better rep- 

 resented by the figures on pi. 66. 



H. MAZENDERANENSIS Nevill. PI. 63, figs. 43-45. 



Umbilicate, depressed, thin but strong, finely, regularly striate' 

 excessively minutely granulate, but not spirally striate ; spire de- 

 pressed conoid, with large smooth blunt apex ; suture distinct ; whorls 

 about 4, regularly increasing, rounded, the last widened, strongly 

 striate above, smooth below, and indented around the umbilicus, sud- 

 denly and deeply deflected anteriorly ; aperture very oblique, ovate ; 

 peristome simple, sharp, thickened with white, the ends converging, 

 ioined by a thin translucent callus ; coloration extraordinarily hand- 

 miefor the group Levantina, consisting of a yellowish white ground- 

 dor, darker above, upon which revolve five chestnut bands ; the 

 fourth and fifth are most intense in color, sharply defined, but here 

 id there with paler spots ; the first and third are less intensely col- 

 ored, narrow and interrupted ; the bands are visible within the aper- 

 ture, Diam. ').">, alt. 18 mill. 



Province of Mezanderan. 



This brilliantly colored species is related to H. dschulfemis, per- 

 haps is only a variety of that form. The description and figures are 

 from Kobelt.
