﻿BARTSCH] notes on the genus sonoreli \ [93 



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

 vol. xt, p. so, 1897. 

 Shell resembling 6". arizonensis in shape, bul larger, with propor 

 tionately smaller aperture. General coloration: pale flesh color; a 

 narmw pale-chestnut band encircles the whorls a little above the 

 periphery, but is visible above the suture only in the last one and one- 

 half turns. The nepionic stage embraces about half a volution, is 

 somewhal flattened, slopes outward, and is marked by rather coarse, 

 wavy, transverse wrinkles; there is no abrupt demarcation between 

 tins stage and the neanic. The neanic portion consists of one and 

 a fourth turns and is marked by rather strong incremental lines upon 

 which is placed the rather feebly developed sculpture characteristic 

 of the section. The ephebic portion consists of three and one-half 

 moderately rounded volutions which are marked by numerous incre- 

 mental lines and by very dense, exceedingly minute granulations, both 

 on the upper and the lower surface. The last whorl is decidedly 

 detlected at the aperture, which is of medium size, subcircular, only 

 slightly expanded, and not reflected. Columella moderately broad 

 and expanded at base, not reflected over the rather wide umbilicus, 

 which appears open to the apex. The type (No. 125,260, U. S. Nat. 

 Museum was collected by Dr. G. P. Merrill below San Ouentin, 

 Lower California. It measures: maj. lat. 22 mm., min. lat. 18 mm., 

 alt. 12.5 mm.; aperture: maj. lat. to. 5 mm., alt. 9.5 mm.; umbilicus 

 about J. mm. 



SONORELLA GRANULATISSIMA Pilsbry 



(Plate XXXII, figure 4) 

 Sonorella granulatissima Pilsbry, Nautilus, vol. xvi, p. 32, 1902. 



Sonorclla granulatissima Pilsbry resembles 5\ hachitana in form 

 but is smaller in every way, with a decidedly smaller umbilicus, and 

 densely, evenly granulose. The type locality is Huachuca mountains, 

 Arizona. The measurements given by Dr. Pilsbry are: alt. to mm., 

 diam. 19 mm.; oblique alt.: aperture 9.7 mm., width 11 mm. An- 

 other specimen is said to measure: alt. 9.8 mm., diam. 18 mm.; 

 oblique alt.: aperture 8.5 mm., width 9.8 mm. 



The U. S. National Museum has two lots (Nos. 130,007, alt. 9,382 

 ft., and 130,008) from Huachuca mountains, and one (No. 124,- 

 479 a ) from Tucson, Arizona.
