Plate II. Fig. 7. 



T. conica, subglabra, fusco-vi rente; spira elevata, ; anfr. 9, planis, 

 lineis duabus fuscis ornatis, quarum inferior in angulum prope suturam 

 revolvit, lineis in anfr. suprerais obsoletis, in ultimo 4 vel 5 conspicuis ; 

 suturis valde impressis ; apertura ovata, intus albida, fusco quadriline- 

 ata; columella incurva, in sinum tenuem producta. 



Shell conic, nearly smooth ; spire elevated ; whorls about 9, 

 flat, with two fine, distant, brown lines on each, the lower one 

 revolving upon an angle near the suture ; lines obsolete on the 

 extreme upper whorls, and increased to four or five on the body 

 whorl, visible also within the aperture; sutures deeply im- 

 pressed; aperture ovate, within whitish, but exhibiting also 

 the brown lines of the epidermis ; columella curved, sinus incon- 

 spicuous. 



Length 0.86 inch (22 millim.). Diam. 0.32 inch (8 millim.). 



Length of aperture 0.33 inch (8 millim.). 



Breadth of do. 0.16 inch (4 millim.).

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

 distinguished by its flat, subangulated whorls. It also exhibits 

 somewhat coarse strise (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 carinate. 



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

 hair-like bands contrasting finely with the yellowish brown 

 color of the general shell.
