Shell small, elongately ovate, with, an acute spire, intense olive 

 green, approaching black, but sub-diaphanous with transmitted 

 light when the shell is a pale sea green, not shining ; whorls 6£, 

 (with the nucleus decollated, ) scarcely convex, sometimes obsoletely 

 ribbed, regularly, distinctly striate spirally, these stria) are close 

 and fine behind the columella. The suture is not impressed, but 

 sometimes rendered faintly corrugate by the obsolete ribs! 

 Aperture entire ovate, labrum thin, produced anteriorly, columella 

 inconspicuous, but slightly flattened in front.

Shell elongate with the spire attenuate, but sometimes ovate 

 with an almost conical spire, thin, shining, pale olive with spots or 

 stripes of pale brown disposed lengthwise. Whorls 6 to 7 

 elongately rounded, sloping, closely, spirally grooved, and in 

 many specimens indistinctly ribbed lengthwise ; suture well 

 impressed, and in the upper whorls having a constricted appearance; 

 aperture rather broadly ovate, labrum thin, produced anteriorly, 

 lip very thinly spread over the columella, which is sometimes 

 rounded, sometimes flattened anteriorly. 



The difference between this shell and the preceding is that it is 

 narrow, attenuated in the spire, pale olive, spotted with brown, 

 and very closely spirally grooved, while the grooves on M. dahtulios 

 are very distant.
