paler; striation sharp; spirals well developed on the last whorl; not eari- 
nate. Alt. 8.8, diam. 14.7 mm. (Pl. XXYV, fig. 36). 
This lot is dwarfed, about the size of O. s. concentrata. 
12. Another lot from Carr Canyon, altitude not stated, contains 
whitish bandless shells and brownish ones, uniform or banded like 
No. 7. One is carinated to the aperture and all are keeled in 
front. The sculpture consists of fine, sharp rib-strie on the spire, 
.and when fresh, young shells show cuticular lamine on the costule, 
larger at intervals and at the periphery. The base has a similar sculp- 
ture. The last whorl is spirally striate above and below. Diam. 21 
mm. (Pl, XXV, figs. 37, 38, 39, 40). 
It may be noted that Dall has reported “a sharply carinated variety”’ 
from Tanner’s Canyon, Huachuca Mountains ties U.S. Nat. Mus., 
AIX, p. 305). 
Mr. Ferriss notes that the young are hirsute. This form diverges 
quite markedly from hwachucana and to some extent parallels O. bar- 
bata of the Chiricahuas. It was found in one small colony only (No. 
79 of Mr. Ferriss’ coll., 87,132, A. N.S. P.). 
13. Miller Canyon, 5,000 feet. Very large, depressed shells with 
0, 1 or 2 bands, ground color fleshy-white or brown. Periphery rounded, 
or in one specimen angular in front (Pl. XXIV, figs. 1, 2, 3, 4, the last 
immature).

14. Miller Canyon, 5,500 feet. Similar to the preceding. 
On the opposite side of the range specimens were taken in Cave 
Creek and Ida Canyons. 
15. Cave Creek Canyon, 5,500 feet. Whitish or brown-banded 
specimens like Nos. 3 and 4 (Pl. X XV, figs. 41, 42, 43). 
16. Ida Canyon. Whitish specimens, angular or rounded in front, 
and with or without a band. The whorl descends more or less in front, 
and some gerontic forms occur. Diam. 19.8 to 22 mm. (Pl. XXV, figs. 
33, 34, 35).

Nautilus, XVIII, p. 113, February, 1905. : 
The shell is calcareous, whitish with corneous and brownish streaks 
and dots, and a dark brown band below the periphery. The upper 
surface is rather rudely wrinkled obliquely, but scarcely shows spirals; 
but the base is closely and in most specimens rather distinctly spirally 
striate. Embryonic shell like that of O. s. huachucana. The whorls 
have an acute, projecting carina which continues to the aperture, and are
