118 STROPHOCHEILUS. 



S. PILSBRYI von Ihering. PI. 17, figs. 46, 47. 



Shell perforate, oblong, moderately solid, chestnut brown, with a 

 blackish line followed by an ill-defined yellow band below the suture ; 

 irregularly plicatulate and beautifully granose microscopically through- 

 out, the granulation barely visible to the naked eye, and arranged in 

 regular spiral series ; spire thick, obtuse. Whorls 5, the first one 

 planorboid, the next tumid above ; last whorl oval, convex, its later 

 half more descending, shortly ascending at the aperture. Aperture 

 ovate, bluish within ; peristome reflexed, red; columella oblique and 

 straight above, concave below, its margin dilated above, almost clos- 

 ing the narrow perforation. Length 48, diam. 24 mill.; aperture 25 

 mill. long.

Strophocheilus pilsbryi v. IHER., Proc. Acad. Nat. Sci. Phila. 

 1900, p. 394, pi. II, f. 4 (August 9, 1900). 



This species seems to be allied to S. rhodocheilus (Reeve), but has 

 not the color-pattern or columellar fold of that species, the aperture 

 is smaller, and the surface irregularly plicatulate as well as granulous. 

 The original description is given above, and the type figured. There 

 are three nepionic whorls, densely striated spirally, the striae granu- 

 lose. An oblique impression marks the end of the nepionic period. 



S. MILLERI var. KRONEI v. Ihering, n. v. PI. 19, figs. 58, 59. 



Shell similar to S. milleri, but broader, more inflated, the aperture 

 more oblique, peristome dark purple, less reflexed above ; spire very 

 dark, being violet under the thin cuticle, the last whorl rich chestnut, 

 glossy with dull zones. Length 62, diam. 32^, longest axis of 

 aperture 34^ mill. 



Brazil: Bio Grande, Prov. Sao Paulo. Type no. 1122 coll. 

 Museu Paulista. 



The type and only specimen I have seen has lost some of the 

 cuticle, but what remains shows the lustrous zones of milleri, with 

 which species it agrees in having 5 whorls, somewhat plicate spire 

 and obliqne last suture. The adnate portion of the reflexed columellar 

 lip is thinner than in milleri, closely appressed and concave, leaving 

 no umbilical chink whatever, and the columella is somewhat sinuous. 

 The spiral striae are less granulose than in milleri. This form may 

 prove specifically distinct.
