The general aspect of this minute species reminds one 

 of a miniature banded Palud'ma. We do not positively 

 assert that it is the Ti\ ? fusca of Philippi, but it bears a 

 mucli greater likeness to the individuals he sent ns, which 

 are, however, larger, more coarsely wrinkled, redder, and 

 rather more elongated, than to the delineation of his species 

 in the " Enumeratio." 



The shell is oval-oblong, thin, semitransparent, glossy, 

 and either quite smooth or merely wrinkled with a few 

 lines of increase. On a pale fulvous, or horn-coloured 

 ground, the penult and ante-penult volutions are encircled 

 by two narrow rufous zones, one near either suture, the 

 lower one of which usually enlarges upon the body-whorl, 

 which has a third or additional band around the extreme 

 base. There are four whorls, of which the apical one is 

 very short and obtuse, the last and the last but one each 

 but moderately longer than the preceding, and all of 

 them more or less ventricose. The penult and ante-penult 

 turns are of moderate height, and are more perpendicular
