repeated on several (leeasioiis. have yielded to date only a single adult 

 living specimen, all the remainder being immature or merely dead 

 shells. While probably occurring all through Mill Creek Caiion, and 

 perhaps neighboring parts of the range in favorable situations, only 

 the one slide of the few so far examined has yielded specimens. A find 

 by Mr. Smith of several shells on or near the surfare leads to the 

 belief that the species is not always, if ever, of strictly subterranean 

 habit, at least not in th(> same sense as SoiiarcJla. 



Epiphragmophora tudiculata rufiterrae, new subspecies 



Shell low conic, rounded, nai'i'owly lunbilicate. Color a warm 

 brown, the apical whorls a little paler, with a broad (1.5-2 mm.), 

 consjiicuous, very dark, chestnut-brown band on the shoulder, bordered 

 above and below by a slightly narrower band much lighter and yellower 

 in tint than the body of the shell. Peristome moderately thickened, 

 scarcely reflexed above. Init more so below, and deflected over the 

 uml)ilicus so as sometimes nearly to cover it. 



Surface very glossy, but roughened by the occasionally quite con- 

 spicuous lines of growth and by the very flue, copious, even malleation, 

 which covers almost the entire shell ; the malleation scarcely developed 

 on the apical whorls or the region immediately adjacent to the 

 umbilicu.s. Neanic whorls very finely radially wrinkled and spar.sely 

 quincuncially papillo.se; earlier succeeding whorls with traces of a 

 delicate incised spiral sculpture. 



Whorls aboiit Sy^, the la.st descending in front. Apei'ture obli(|ue, 

 the end of the peristome somewhat converging and connected by a thin, 

 transparent, whitish callus. 



Greater diameter of largest shell, 2S nun., of tyjjc. 27 mm.. of 

 smallest. 22.5 mm. Lesser diameter of largest shell, 22 mm., of type, 

 21mm., of .smallest, 17.5mm. Height (umbilicus to apex), of largest 

 .shell, 14.5 mm., of t.vpe, 13 mm., of .smallest, 11.0 mm. 



Type. — Cat. no. 3481 of the writer's collection; paratypes in the 

 collections of the University of California and the California Academy 

 of Sciences.

 under boards, near the southeastern entrance to Canon Crest Park.
