Yar. TAURICA (Krynicki) Mousson. PI. ($7, fig. !5. 



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

 taurica. It differs from radn>*>i 7^\. (which usuallv is considered \\ 

 synonym of tauricci), very materially; shows only .-(nite indistinct 

 traces of longitudinal streaks, but instead of them two very .-harplv 

 outlined broad reddish brown bands. The columella is notably 

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

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

 its insertion. (Kobelt. )

im perforate 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.

< oncasus. 



Differs from H. lucorum 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, partly flesh-color; the parietal callus is very thin. 

 white. 

 II. SCHLAKFUI Mousson. PL 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 band.- usually 

 narrower, rudely irregularly coarsely obliquely striate and with fi 

 irregular impressed spiral striae; spire conoidal, apex very obi 

 smooth, shining, rather large, sutures slightly irregular, wel 

 pressed; whorls 4i, con vex, rapidly widening, especially t 

 body-whorl globose, a trifle indented around the ax.s, Borne* 

 descending anteriorly; aperture rotund-lunate, oblique, bw 

 white with brown hands within ; peristome very regularly arc 

 the columella arched, outer and basal margins simple, coll 

 margin dilated, reflexed and adnate over the axis, deepb
