tome yellow, outside and in, edged narrowly wdth white, rather 

 broadly and flatly reflected, the terminations very slightly approach- 

 ing above; columellar lip with a thick, prominent flange enclosing 

 the umbilical chink, dilated; parietal callus very thin.

This species is related to D. strigatus Sby., but it differs by being 

 more obese, by the greater development of spiral striation, and in 

 having a yellow lip instead of violet as in D. strigatus. D. similaris 

 Moricand is similar in shape and color of the lip, but it differs con- 

 spicuously in color pattern. 



Two dead specimens were taken at Camp 40, M. & M. R. R., and 

 several dead specimens at Camp 39, only one being perfect and as 

 well preserved as a living shell. Many of these shells, as well as 

 many others taken on the right of way of the M. & M. R. R., were 

 more or less damaged by fire used in clearing. 

 Drymaeus linostoma suprapunctatus n. subsp. PI. XXIII, figs. 5, 6, 7, 8. 



Shell oblong, thin, diaphanous, glossy, shining, appearing nearly 

 smooth to the naked eye, but, under a glass, showing typical Drijmmus 

 sculpture on the nepionic If whorls; afterward with irregular growth 

 lines and fine, indistinct, wavy incised spiral lines throughout; dirty 

 white, occasionally becoming roseate toward the lip, with wide, 

 well-spaced, longitudinal flames of brown or brownish-violet, inter- 

 rupted or crossed by a spiral row of dots just above the periphery 

 of the whorl. Whorls 6, slightly convex, separated by deep, smooth 

 sutures; spire conic, obtuse at the apex; last whorl subcylindrical, 

 more than two thirds the total length. Aperture large, oval, a little 

 oblique, light colored within except where the external markings 

 show through, and shading to roseate on the lip in some specimens; 

 peristome rather broadly expanded but not recurved; columella 

 twisted, with an extremely narrow flange so reflected as to leave 

 little or no umbilicus; extremities approaching sharply; parietal 

 callus very thin. 



Alt. 26.5, diam. 11.5, alt. of last whorl 18.5, alt. of mouth 12.25 

 mm. Type. A specimen with broken spire measures alt. ?, diam. 

 12, alt. of last whorl 19.5, alt. of mouth 13 mm. 



This variety differs from the type of D. linostoma (Orb.) by the 

 interruption of the vertical stripes and the development of a spiral 

 series of dots above, by the closure of the umbilicus and by the pale 

 aperture. In linostoma the umbilicus is distinct, the stripes are 

 continuous and the peristome of a deep violet color. D. suhsimUaris
