Long., 6 "50, Lat., 2^25 mill. 



A handsome fusiform shell, whorls probably ten, the apical 

 being absent in our specimens, whorls slightly angled and 

 ventricose, ribs and transverse lira? of about equal size, the former 

 being small and feeble ; at the sutures and round the middle 

 of the last whorl are ochre bands. Outer lip much thickened 

 and expanded, sinus spoon-shaped, wide and broad, outer lip 

 finely denticled within, columella also denticulate. (Orjo-avpos, 

 treasure). 



M. (Glyphostoma) thyridota sp. nov. (PI. X., fig. 35). 

 G. testa brevi, pyramidata, unicolore, albida, anfractibus sex, 

 turr/tis, ventricosis, apud suturas angulatis, longitudinaliter 

 cottspicue crassicostatis, transversim pauci/iratis, apud medium 

 anfractuum ttno ordine prof undo fovea rum instructis, in ultimo

 tnuJtum incrassato, intus quadri-denliculato, columella mi/iu- 

 tissime denticulata, sinu profundi in labro exteriore eft/so. 

 Long., 4'5o, Lat. 2 mill. 



A pure white, curtly pyramidal species, the surface not 

 shining. Whorls six, turreted, angled at the suture, ventricose, 

 longitudinally thickly ribbed, transversely ornamented with few 

 lirations. In the middle of the upper whorl and doubly-ranked 

 in the last whorl, are transverse regular deep pittings, squarrose, 

 profound, between the ribs, which suggest the trivial name. 

 The mouth is narrowly oblique, outer lip thickened, furnished 

 with four strong denticles, the columellar teeth are more obscure 

 and feeble. Only one specimen, and that slightly worn ; but 

 the characters are so remarkable as to excuse description from 

 such scanty material. (6vpi&a>TO<s, furnished with windows or 

 doors.)
