The form, size, and color is like M. siiUirata, Reeve, but the 

 sculpture is quite different, that species having no longitudinal 

 ridges, and the transverse grooves are described as deep and 

 punctured, and the intermediate ridges slightly granose. 



MiTRA RORATA. T. modlca, solida, lanceolata, cinerea rubi- 

 ginoso-marmorata, clathris longitudinalibus quadratis ad 30 et 

 striis tenuibus volventibus decussata : spira elevata, anfr. 9-10 

 planis postice angulatis ; ultimo cylindraceo antice sensim atten- 

 uate, dimidiam long, testae superante : apertura angusta, labro 

 acuto, roseo, 13-sulculato ; columella 4 plicata ; rostro lato oblique 

 reflexiusculo ; fauce incarnate. Long. |; lat. y^o poll. Hah. — ? 



The form and sculpture is much like that of M. hehes. Reeve, 

 but the coloring is more like M. crenifera. It is more cylindri- 

 cal and the bars are less prominent than M. cophina^ besides the 

 difference in coloration. 



MiTRA CAPiLLATA. T. parvula, elongata, ovato-fusiformis, 

 polita, rufo-castanea lineolis longitudinalibus flexuosis croceis 

 ornata : spira acuto-conica, anfr. 7 convexiusculis, ultimo bifariam 

 attenuate, antice striis prominulis cincto ; sutura impressa : aper- 

 tura ^ long, testes, angusta, elliptica ; columella 3-plicata, postice 

 callosa ; fauce lurido. Long. -^-^ ; lat. ^ poll. Hab. Madeira- 



This beautiful little shell is easily identified by its dark ma- 

 hogany color and its delicate yellow lineations, like those on some 

 species of Neritina. M. semen^ Reeve, which is not so slender, 

 and has fewer and broader lines, is the only species approach" 

 ing it.
