Obs, May be compared with M. Taitana Lea, but may be 

 distinguished by its flat, subangulated whorls. It also exhibits 

 somewhat coarse striae (amounting nearly, .if not quite, to ribs 

 in some specimens) upon all the whorls, even the body whorl 

 is no exception. The sutures are, also deeply impressed, the 

 contiguous whorls shelving towards each other to form quite a 

 furrow there. Upper whorls car in ate. 



It is a very beautiful species, the distinct, reddish brown, 

 hair-like bands contrasting finely with the yellowish brown 

 color of the general shell.

T. conica, glabra t tenui, fusca ; spira modice elevata : anfr. 6, supe- 

 rioribus bifa c ciatis et supra suturam subangulatis, ultimo convexo, nigro- 

 4-fasciata ; suturis impressis ; apertura ovata, intus fasciata ; columella 

 lineari, parum incurva, purpurea, in sinura parvurn producta. 



Shell conical, smooth, not much or acutely elevated ; thin, 

 brown, whorls about 6, sub-convex, often slightly angulated 

 near the suture below : sutures impressed ; body whorl not 

 large, a little angulated, ornamented with four very dark bands, 

 the upper and lower of which are distant, and the central ones 

 approximate or confluent: aperture somewhat large, elliptical, 

 banded within ; columella regularly, but not remarkably curved 

 or indented, with a small sinus. 



Length 0.58 inch (15 millim.). Diam. 0.27 inch (7 millim.). 



Length of aperture 0.27 inch (7 millim.).
