STROPHOCHEILUS. 119 



Var. IGUAPENSIS n. v. PI. 18, figs. 48, 49. 



Shells denuded of cuticle have the spire violet, the last whorl paler, 

 flesh-colored, lip pink. The last whorl and aperture are broader 

 and shorter than in milleri. Lip well reflexed ; the reflexed, thick 

 columellar lip leaves an umbilical chink below; columella straight. 

 Length 59, diam. 32, longest axis of aperture 32^ mill. 



Brazil: Iguape, S. Paulo (Dr. H. von Ihering). 



In this variety the length of the aperture equals the diameter of 

 the shell, while in milleri and Icronei it exceeds it slightly. The 

 crowded, fine spiral stria? are smooth, while in milleri they are 

 granulose. 



S. CALUS n. sp. PI. 18, figs. 46, 47. 



Shell deeply rimate, oblong, solid and strong; rose colored, fading 

 to white in some places, under a thin yellow cuticle (which is in 

 large part wanting in the type). Surface densely sculptured with 

 waved stria?, which on the last whorl anastomose to form a netted 

 pattern ; conspicuously malleated. Whorls 5^, the first obtuse 

 above, the earlier 3 composing the conic, closely obliquely striate 

 nepionic shell. Sutures moderately impressed, beyond the nepionic 

 shell becoming progressively more oblique to the last half turn, 

 which is about parallel to that above it, and ascends in front. 



Aperture slightly oblique, ovate, flesh-tinted within, peristome very 

 broadly reflexed and recurved, the outer lip regularly arcuate, its 

 upper half rose colored, lower half with the basal lip yellowish ; col- 

 umellar margin broadly reflexed, standing free above the rather long 

 curved, compressed axial chink, rose colored; columella strongly 

 folded, the fold white; parietal wall covered with a thick, trans- 

 parent, roseate enamel. Length 63, dianu 30, longest axis of 

 aperture with peristome 36 mill. 



Brazil. (Type no. J 4668, coll. Amer. Mus. Nat. Hist.) 



This beautiful species has a stronger columellar fold than S. alme- 

 ida, is heavier, and there is no umbilical perforation as in that spe- 

 cies, but merely a rather long, curved chink, over which the wide 

 columellar lip projects. The apex is more acute than in S. erythro- 

 soma. It may be related to S. rhodocheilus (Rve.) but has neither 

 the sculpture or color pattern described for that species. S. contor- 

 tuplicatus (Reeve) has a much narrower peristome and different 

 sculpture. In S. calus there is no minute granulation, and no spiral 

 striation.
