Closely allied to J). onager; but the aperture is always produced 

 or channelled more or less at the outer basal portion, there are some 

 ochre-colored stripes among the purplish and white ones, and dots are 

 sparsely scattered over the surface. The pattern of coloring is not so 

 mutable as in onager, the variation being in the width of the stripes, 

 greater or less prominence of the ochre coloring, and number of dots. 

 There is wide variation in the shape of the aperture, but the outer lip

Hidalgo reports riniiiH'iis from Rio Janeiro, on the authority of 

 Paz ; but I do not think it inhabits that province.
