76 ANCEY: ON THE GENUS ASHMUNELLA. 



lips is a small, low, simple, short, oblique parietal tooth or ridge, with 

 the outer end nearer the pillar. 



Alt. 5'5 to 7; diam. 13-5 to 15 millim. 



Loc. — White Oaks, New Mexico, at an altitude of 7,500 feet 

 (Ashmun). 



Nearly allied to A. fliomfioniana, but wanting the denticle within 

 the outer li]i, and with the basal edge notched, not toothed.

Nautilus, 1899, vol. xii, p. 131. 



Shell depressed, shining, dark horn colour or even reddish ; the 

 usual striae distinct, but not sharp, spiral impressed lines visible with 

 a lens; whorls 5^, rounded; aperture oblique, semilunar; lip expanded, 

 broad, reflected, strongly tinged with pinkish or coffee colour, edentu- 

 lous, except that the basal part bears within a distinct but slight 

 callus, which is more or less livid ; parietal denticle either rudimentary 

 or distinct, but never large; umbilicus broad, exposing the penultimate 

 whorl. 



Alt. 8 to 10; diam. max. 17 to i8'5, min. i4"5 to 15 millim. 



Loc. — ^Near Baldonado Springs, Capitan Mts. (Sierra Capitana), 

 Lincoln Co., New Mexico, altitude 8,200 feet (Ashmun).

Differs from A. cldricalniana in size, being only 14 mm. in greatest 

 diameter and 7 mm. in height ; also the surface when strongly magni- 

 fied is seen to be covered with sharp, delicate, spiral, incised lines 

 with wider interspaces. The number of whorls is but slightly less, if 

 at all different. If the element of actual size be ignored, the figure 

 given by Dall of A. cJiiricahuana will equally well represent the species 

 in question. A careful scrutiny of a series of A. c]nricahiia?ia shows 

 that incised lines occur quite frequently in some individuals, so that 

 the species under discussion may only represent a dwarf race of it 

 with more emphatic sculpture. I fully share Dall's opinion. 



Loc. — Bland, New Mexico, altitude 8,000 feet (Ashmun). 



Ashmunelia ehirieahuana (Dall).

also 1896, vol. xviii, p. 341, pi. xxxii, figs. 9, 10, 12. 

 Shell depressed, thin, polished, and of a dark brownish colour ; 

 whorls 5I, sculptured only with fine incremental lines; sutures distinct, 

 whorls moderately rounded ; periphery rounded, the termination of
