 seems a little less enlarged below. The curvature of the col- 

 umella varies, but it seems always to be quite abruptly trun- 

 cated. 



7. 0. PAIVANA Pfeiffer. PL 32, fig. 27. 



One of the original lot, here figured, is more slender than 

 Pfeiffer's type. The first l 1 /^ whorls are smooth and enlarge 

 very rapidly, forming a bulbous apex. The following whorl 

 is narrower, and sculptured with vertical grooves at unequal 

 intervals. The following whorls have the same sculpture and 

 enlarge slowly to the last, where the suture descends very 

 rapidly. The last whorl is widest at the shoulder, tapering 

 thence towards the base. The specimen is bleached, but on 

 the white ground shows reddish streaks behind the variceal 

 grooves, and behind the lip the whole surface is reddish. The 

 aperture is extremely narrow, hardly widened basally. The 

 outer lip arches strongly forward, and recedes conspicuously 

 towards the base. The columella is slightly concave close to 

 the abrupt truncation. Length 14.75, diam. 3.5, aperture 7.5 

 mm. ; whorls 7. The shell is fully adult. 



Pfeiffer's type measured: length 15, diam. 4, aperture 8.66 

 mm. ; whorls 7 to 8.

Though very distinct by its narrow mouth and sinistral 

 coil, this species is related to 0. cleriei and 0. microlestes by 

 its sculpture, like that of Varicella.
