HELIX-EUHADRA. 117 



on several of the inner whorls ; spire low-conical, obtuse at apex ; 

 sutures scarcely impressed. Whorls 5, the first two smooth, shining, 

 corneous ; last whorl rapidly widening, angular at the periphery, 

 convex beneath, scarcely deflexed at the aperture ; aperture ob- 

 lique, rounded-truncate, of a livid-bluish tint inside ; peristome ex- 

 panded, not thickened, flesh-colored, its margins converging, the 

 basal dilated ; parietal callous light ; umbilicus funnel-shaped. 

 Alt. 25, diam. maj. 43, min. 35 mill. ; umbilicus 4 to 5 mill. wide.

Described and figured from a specimen in the collection of L'abbe 

 A. Vathelet. The deflection of the last whorl shown in the figure 

 is caused by an injury received by the specimen. It would be very 

 slight in an uninjured shell. The species is allied to H. sivinhoei 

 and If. caspar i. 



H. AMMIRALIS Pfeiffer. Unfigured. 



Shell umbilicate, turbinate-depressed, rather solid, rather rudely 

 striate all over, tawny or yellowish, generally ornamented with a 

 peripheral blackish-chestnut band ; spire regularly conoidal. Whorls 

 6J, a trifle convex, slowly widening, the last a little descending in 

 front ; periphery carinated, base convex, subcompressed around the 

 narrow chestnut umbilicus. Aperture oblique lunate ; peristome 

 liver-colored, narrowly expanded, the columellar margin reflexed 

 above. (Pfr.) Alt. 20, greater diam. 36, lesser 33 mill.

An unfigured form, probably grouping here. 



Group of H. succincta Ad. 



The shells of this group are depressed, conical above, convex 

 below, carinated at the periphery. The umbilicus is narrow but 

 deep and cylindrical, and partly covered by the reflexed columellar 

 lip. The surface is obliquely striate, and in some species there are 

 superficial spiral strise. In fact, the sculpture in certain of the 

 forms here grouped reminds one of that of Camcena s. s. ; in others 

 of the group of H. peliomphala ; and in H. ccdiginosa it is micro- 

 scopically granulated. The nucleus is minute ; the whorls are
