Obs. Somewhat allied to M. rufescens Lea, in general form, 

 but that species has regularly convex whorls and no bands, 

 and has at least two more whorls. The number of whorls 

 in this species cannot, however, with certainty be determined, 

 since in all my specimens, seventy or eighty in number, every 

 one is decollate, but the form does not indicate the loss of more 

 than two whorls at most, and only four are present. M. TV- 

 fescens is described as having eight. A few of the specimens 

 are irregularly and strongly striate on the body whorl.

T. conico-ovata, glabra, tenui, fusco-virente ; spira obtuse elevata ; 

 anfr. 6, superioribus, subplanis, ultimo convexo, interdum trifasciato ;
