130 TROCHOMORPHA. 



obscurely multilineate with tawny above, yellowish-corneous beneath, 

 having a narrow dark chestnut band below and another above the 

 periphery, the latter ascending the spire ; periphery and suture pale. 

 Surface having light growth lines but no spiral sculpture. 



Spire convex, low ; whorls 5&, slowly widening, separated by a 

 shallow suture edged by a white line ; last whorl slightly descending 

 in front. Aperture very oblique, irregularly oval, purplish within ; 

 upper lip thin, arched forward; basal lip callously thickened, 

 slightly subreflexed. 



Alt. 7, diam. 15 mill. ; apert. alt. 6, width 7 mill.

Belongs to the group of meleagris Pfr. and partunda Ang., but 

 the umbilicus is much more widely open and the coloring differs. 

 My description and figures are drawn from specimens received from 

 Mr. Sowerby. 



T. HENSCHEI Pfr. PI. 20, figs. 28, 29, 30. 



Shell perspectively umbilicated, the width of the umbilicus con- 

 tained 5? times in the diameter of the base; solid, opaque, slightly 

 shining, buff-brown colored with five chestnut-brown bands, one a 

 short distance below the suture, the next narrower, just above the 

 white-edged, acute peripheral keel, the third wider, just belowthe keel, 

 the fourth in the middle of the base, the fifth within the umbilicus. 

 Surface having fine growth lines but no spiral strise. Spire convex, 

 apex obtuse ; whorls 5i, slightly convex, separated by a slightly 

 impressed, narrowly white-edged suture; the last whorl acutely 

 keeled, with flattened base. Aperture very oblique, showing the 

 bands within ; upper lip arched forward, rather thin ; basal lip 

 slightly arcuate, thickened ; columellar lip strongly arched. 



Alt. 7, greater diam. 17, lesser 14 2 mill.

Helix henschei PFR., Mai. Bl. 1867, p. 197 ; Monogr. v, p. 495. 



In figure 29 of my plate, the outer part of the basal lip should 

 have been straighter and the columellar part more strongly arcuate. 

 The above description and the figures are drawn from a specimen 

 kindly supplied by my friend, John Ponsouby, of London. I see 

 no difference whatever between this and the previously described H. 

 ludersi Pfr.
