206 AMPHIDROMUS, GROUP XIII. 



black-brown apical dot ; the next whorl is paler with a series of 

 brown stripes or spots bisected by a median light girdle ; the ground- 

 color then changes to whitish, and then pale stra w -yellow, which 

 becomes more intense toward the base, and may be either uniform 

 or with "one to ten brown spiral lines, which are sometimes contin- 

 uous, sometimes interrupted." In some specimens the brown flames 

 of the early whorls continue to the last, where they spread over the 

 whole surface (figs. 19, 20). Whorls about 6-jj, a little convex- 

 Aperture white or tinted within, becoming brown or lilac near the 

 reflexed, intensely black-brown peristome. Columella dilated, black- 

 brown outwardly, lilac within, continuous with the parietal callus, 

 which is brownish toward the edge, translucent lilac or nearly color- 

 less within.

Although extremely variable in color, the black lip is constant in 

 the specimens collected. To the type figure (fig. 17), I add others 

 representing varying phases of coloration, figs. 19, 20 representing a 

 pattern of which only very few specimens occurred.

"Shell sinistral, elongately conical, slightly striated, imperforate, 

 varying much in color, yellow with green streaks, pale or orange 

 yellow, with the upper whorls yellowish or brown, apex yellow or 

 black brown, upper whorls nearly always with brown flames or 

 blotches, lower whorls commonly with a white zone beneath the 

 sutures ; whorls G, slightly convex ; aperture elongately-ovate, 

 angular above, angularly rounded and slightly effused beneath, occu- 

 pying with the peristome about half the length of the shell, interior 

 white ; lip strongly reflected, so as to reach and even partly to cover 

 the back side of the shell and forming a canal having the appearance 

 of a very thick peristome; columella thickened, like the lip of a pale 

 rose-color, margins connected by a thin callosity" (Schepm.).
