Shell small, depressed, flesh -colored, with a narrow brown band 

 encircling the whorls a little above the periphery. This shell ap- 

 proaches very nearly S. fisheri, Bartsch but differs in color, size, and 

 in having a wider umbilicus.

 Argus range, Inyo Co., California. Cotypes in tlie geological 

 museum of Stanford University, and A. N. S. Phila.

 5.7 mm., aperture : maj. lat. G mm., alt. .t.3 mm., unibilicus, '2 nun. 



EpIPHRAGMOPHOKA DUPETITHOL'AKSI cuestana, n. subsp. 



Shell large, depressed, polished. obli(piely striated, with seven 

 whorls, the last whorl descending slightly near the aperture ; deeply 

 and widely umbilicated, showing three volutions ; lip slightly re- 

 flexed, the ends approaching ; color translucent brown, circled near 

 the top of the whorls by a dark brown band edged with yellow. 

 The type measures; greater diam. 26^ mm., lesser diam. 22^ 

 mm., alt. l.*)^ mm. ; aperture, width 16 mm., alt. \S^ mm., includ-
