EPIPHRAGMOPHORA TRASKII TULARICA, new subspecies.

 Epiphragmophora traskii tularensis Pilsbry, Clas. Cat. with Loc. Land Shells of 



Amer. North Mex., 1907, p. 5, nomen nudum. 



Shell subgloboso, very dark colored, with the chestnut band v^^ry 

 broad. The axial wrinkling of the nuclear sculpture is very strongly 

 developed, the individual wrinkles being finely granulated. The 

 larger papillations, which form the obliquely protractively slanting 

 lines on the nucleus, are not nearly as strongly developed here as on 

 the other races and require search to be seen. This sculpture does 

 not appear to extend beyond the nuclear turns, but is replaced by 

 the incised spiral sculpture which consists of closely spaced micro- 

 scopic spiral striations and deeper, distantly, irregularly distributed, 

 stronger lines. 



The type and another specimen (Cat. No. 60009, Philadelphia Acad- 

 emy of Natural Sciences Collection) come from Frasers Mills, Tulare 

 County, California. The type has 5.6 whorls and measures, greater 

 diameter, 21 mm.; altitude, 17.4 mm. The other specimen has 5.5 

 whorls and measures, greater diameter, 21 mm.; altitude, 15.6 mm. 



EPIPHRAGMOPHORA TRASKH ZECHAE PHsbry.

Epiphragmophora traskii zechae Pii.sbry, Nautilus, vol. 29, No. 9, pp. 104-5, pi. 3, 

 lower figures (3), Jan., 1916. 



Shell very large, decidedly flattened, widely, openly umbiHcated, 

 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-bufi"; 

 there is a chestnut-brown band at the shoulder (about 2 mm. wide), 

 bordered with inconspicuous, hardly noticeable bands paler than the 

 ground color." The characteristic distantly spaced, obliquely pro- 

 tractively arranged papillation is almost obsolete in the nuclear 

 whorls, as well as on the rest of the shell, appearing only as distantly 

 scattered pustules, usually best expressed near the suture, excepting 

 immediately behind the aperture where they are strongly developed 

 on the upper surface and a Uttle less so on the lower. In addition to 

 the papillation the whorls are marked by rather strong incremental 

 Hues which are equally developed on the upper and lower surface. 

 No spiral striations are present. Aperture broadly lunate, decidedly 

 wider than high; lip thin, the upper margin scarcely expanded, the 

 outer slightly expanded, the basal very narrowly reflected; columel- 

 lar margin broadly dilated. 



The type (Cat. No. 113426, Philadelphia Academy of Natural 

 Sciences) measures: altitude, 15.2 mm.; diameter, 31 mm.; aper- 

 ture: altitude, 14.3 mm.; width, 17.8 mm.
