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

 rugose; whorls 4 or slightly move, 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 gidttit<(, its margins converging, but not joined by a callus ; peri-

Described as H. dschulfensii. II. tljiitfi'itti* Muuss. is the same. 

 There are in this species, as in H. f/ntt<it<t, 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.

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. 

 joined by a thin translucent callus ; coloration extraordinarily hand- 

 some for the group Lennitina, consisting of a yellowish white ground- 

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

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

 and there with paler six its ; the first and third are less intensely col- 

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

 ture, Diam. 35, alt. IS mill.
