104 THE NAUTILUS. 



Mr. Conrad also observes that mature specimens of U. cor are 

 sometimes produced and cuneiform behind, " like some varieties 

 of triangularis of Raf.," (a species, in Mr. Conrad's estimation 

 at that time, embracing the group of pyramidatus etc. 



A NEW CALIFORNIAN LAND SNAIL. 



BY HENRY A. PILSBRY. 



EPIPHRAGMOPHORA ZECH.E n. sp. PI. Ill, lower figs. 



The shell is strongly depressed, umbilicate (width of umbi- 

 licus contained nearly eight times in greatest diameter of the 

 shell), rather thin. The whorls of the spire and as far as the 

 front of the last whorl are dilute cinnamon, then changing to 

 ecru-olive or dark olive-buff ; there is a chestnut-brown band at 

 the shoulder (about 2 mm. wide), bordered with inconspicu- 

 ous, hardly noticeable bands paler than the ground-color. 

 Surface is glossy, distinctly, irregularly striate, and immediately 

 behind the lip it is closely and minutely granulose. The spire 

 is a little convex, whorls 5f, moderately convex, slowly increas- 

 ing to the last, which is about double the width of the preceding, 

 and decends a little in front. The aperlure is broadly lunate, 

 decidedly wider than high. Lip thin, the upper margin scarcely 

 expanded, outer very slightly, basal very narrowly reflexed, 

 the columeller margin broadly dilated. 



Alt. 15.2, diam. 31 mm. ; aperture, alt. 14.3, width 17.8 

 mm. 



Habitat, San Antonio Canyon, in the San Gabriel Mts., west- 

 ern edge of San Bernardino Co., California, at about 5000 ft. 

 elevation (Miss Lilian Zech). 



This fine species will probably prove to belong to the Helmin- 

 thoglypta group, in which it most resembles H. sequoicola 

 (Cooper); yet the absence of malleation on the last whorl and 

 of granules on the spire are features more like Sonorella. 



Miss Zech gives the following account of the locality. 



The specimen was found in a narrow, winding canyon branch- 

 ing from the main San Antonio canyon at 4700 feet and at this 

 point, some two or three hundred feet higher as near as I can
