HELIX-IBERUS. 237 



and irregularly malleated. Buff-whitish, ornamented with five nar- 

 row, obscure, interrupted bands ; spire depressed-globose, apex 

 rather large, obtuse, smooth ; whorls 5J, rapidly increasing, the first 

 two smooth, round, the following convex with distinctly subserrate 

 carina in the impressed suture, the penultimate whorl convex ; last 

 whorl inflated, very indistinctly angulate at the periphery, excavated 

 at the place of the umbilicus, the base rounded ; in front it descends 

 slightly at first and then is deeply and abruptly deflected. Aperture 

 very oblique, broadly rotund-ovate, distinctly lunate ; peristome 

 acute, narrowly reflected outwardly, basal margin distinctly lipped 

 with white ; margins converging and joined by a callus which is 

 usually very thin but sometimes thickened and brown tinted, the 

 basal margin calloused, dilated, at first obliquely ascending and 

 sometimes obtusely toothed, then directed vertically or toward the 

 right, and bounded outside by distinct grooves. (Kob.~)

Shell covered umbilicate, depressed, solid, rudely and closely

 last whorl toward the aperture, here and there malleated ; having a 

 satin like lustre ; bluish-white, having very obsolete brown bands 

 and scattered brownish-black dots ; spire little elevated, apex large, 

 obtuse, bright reddish- corn eons; whorls 4J, separated by a linear 

 subimpressed suture, slightly convex, hardly carinated ; the last 

 compressedly rotund, descending in front, and then suddenly much 

 deflected ; base slightly convex or somewhat flattened ; aperture very 

 oblique, rounded-ovate, lunate ; peristome slightly reflected through- 

 out, thickened with whitish, somewhat obtuse; the margins converg- 

 ing, joined by a very thin callus ; basal margin thick, reflected, hav-

 almost closing the umbilicus. (Kob.*)
