Yar. TAUKICA (Krynicki) Mousson. PI. 67, fig. !5. 



The example here figured was sent me by Mousson as his type of 

 ttnirica. It differs from rinliu^i /gl. (which usually is considered a 

 synonym of frn/r/ra), very materially; shows only quite indistinct 

 traces of longitudinal streaks, but instead of them two very sharply 

 out lined broad reddish brown bands. The eolumella is notably 

 callus, with distinct lip, and the margins of the lip are joined by a 

 thin white callus; the eolumella also is white, with a brown spot at 

 its insertion. (Kobclt.) 



II. IIADIOSA Ziegler. PI. 57, fig. -ID. 



Imperforate or subimperforate, globose; color-pattern a combina- 

 tion of spiral bands and oblique streaks of chestnut on white ground 

 the bands diffuse and coalescent into two on the body-whorl, the 

 longitudinal streaks predominating; upper whorls showing two or 

 three narrow bands, the inner two whorls unicolored, corneous ; 

 body-whorl globose, indented around the axis. 



Alt, 45, diam. 42 mill. 



Caucasus. 



Differs from If. li/rorinii in the preponderance of the longitudinal 

 streaks over the revolving bands; there is a narrow white zone, 

 more or less distinct, encircling the periphery ; the columellar lip 

 is partly white, {tartly flesh-color; the parietal callus is very thin, 

 white. 



H. ycuLAKFLir Mousson. PI. 68, fig. 12. 



Covered perforate, globose, solid, yellowish or soiled white, with 

 five spiral brown bands, generally not sharply defined, the second 

 and third usually coalescent, the upper and lower bands usually 

 narrower, rudely irregularly coarsely obliquely striate and with fine 

 irregular impressed spiral striae; spire conoidal, apex very obtuse, 

 smooth, shining, rather large, sutures slightly irregular, well-im- 

 pressed : whorls 4'., convex, rapidly widening, especially the last; 

 body- whorl globose, a trifle indented around the axis, somewhat 

 descending anteriorly ; aperture rotund-lunate, oblique, brownish 

 white_with brown bands within ; peristome very regularly arcuate, 

 the columella arched, outer and basal margins simple, columellar 

 margin dilated, reflexed and adnate over the axis, deep brown in 

 color. Diam. 51, alt. 50 mill. 



Epirns. 



The narrower aperture, adnate columellar lip, completely closing 



the perforation, and of a dark brown color, will separate this form
