﻿194 SMITHSONIAN MISCELLANEOUS COLLECTIONS [VOL. 47 



Epiphragmophora hachitana (in part) Dall, Proc. U. S. Nat. Museum, 

 vol. xix, pp. 339-340, pi. xxxi, figs. 7, 10, 1896. 



Epiphragmophora hachitana (in part) Pilsbry and Johnson, Nautilus, 

 vol. xi, p. 59, 1897- 

 Shell large, depressed, light-brown horn color above, lighter be- 

 low, with a broad brown band bordered on each side by a lighter 

 zone encircling the whorls a little above the periphery. This band 

 can be seen on all the ephebic whorls above the suture. Nepionic 

 portion a little less than half a whorl, somewhat flattened and out- 

 ward-sloping, marked by a few moderately strong transverse 

 wrinkles. The neanic stage embraces one and one-half turns ; the 

 incremental lines are moderately well marked, very wavy, and closely 

 placed ; the characteristic supersculpture of this part is extremely 

 rine, with the lines placed so closely that the complete effect at first 

 appears granular. The ephebic stage consists of three depressed, 

 moderately rounded whorls, which are less convex above than below 

 and are marked by many strong incremental lines and numerous 

 microscopic granulations. The last whorl is considerably deflected 

 at the aperture and shows a tendency to become angular at the pe- 

 riphery. The aperture is moderately large, subcircular. very oblique, 

 expanded, and slightly reflected ; columella moderately expanded at 

 base and scarcely reflected over the rather large umbilicus, which 

 appears open to the summit. The type (No. 130,009, U. S. Xat. 

 Museum) and five additional specimens were collected by Maj. E. 

 A. Mearns, U. S. A., at Tanners canon, Huachuca mountains. Ari- 

 zona. The type measures: maj. lat. 26.5 mm., min. lat. 21.1 mm., 

 alt. 12 mm.; aperture: maj. lat. 11.8 mm., alt. 10.5 mm.; umbilicus 

 about 4 mm. Two additional lots (Nos. 129,136, 125,598) come 

 from the same mountains, the latter from Fort Huachuca. 



SONORELLA MEARNSI new species 

 (Plate XXXII, figure 2) 



Epiphragmophora magdalenensis (in part) Dall, Proc. U. S. Nat. Mu- 

 seum, vol. xix, p. 339, 1897. 

 Shell similar to 5. dalli in shape and coloring, but only two-thirds 

 as large. The nepionic stage consists of about one-half of a volu- 

 tion, is moderately rounded, and is crossed by a few prominent trans- 

 verse wrinkles. The neanic stage embraces one and one- fourth 

 turns, and is marked by irregular, fairly strong incremental lines and 

 the characteristic sculpture of the section, which is extremely fine and 

 closely placed as in S. dalli. Ephebic whorls two and one-third 

 rather depressed, moderately rounded, considerably more convex be-_
