be synonymous, but it has the columella shaped very differently at 

 the lower part. (PI. 61, fig. 13.)

Shell umbilicate, conical, very solid, whitish, unicolored or 

 obscurely striped or maculate with brown or buff; lusterless ; spire 

 conical ; apex acute ; sutures impressed ; whorls 6 to 7, convex, the 

 last with a tendency to be flattened around the middle ; the entire 

 surface covered with sharp close uneven spiral riblets with deeply 

 incised interstices, and very fine, close, longitudinal growth-lamellae, 

 forming compressed beads on the lirse, and generally lamellae in 

 the interstices. Aperture oblique, rounded-quadrangular, with 10 

 or 11 plicae within, which attain the edge of the lip. Columella 

 short, toothed below, concave and somewhat expanded above. Um- 

 bilicus with a smooth funicle, not very prominent, within.

Umbilical funicle not nearly so strongly developed as in M. 

 calliferus. This species has a great similarity to the shell described 

 as Trochus corrugatus by Philippi ; but as Dr. Fischer has pointed 

 out, that is a different species on account of the smooth inside of the 

 aperture. 



M. PATRICIUS Philippi. PI. 41, figs. 30, 31. 



Shell deeply umbilicated, thick, orbicular-conoid, shining, whitish- 

 ashen, punctate with brown or blackish-violet ; spire acute ; whorls 

 7, scarcely convex, separated by a canaliculate suture; spirally cin- 

 gulate, the cinguli narrow, remote, granose, 4 to 5 on the penulti- 

 mate whorl ; last whorl subbiangulate in the middle, encircled by 

 unequal line ; base slightly convex, rad lately striate and with about 

 8 white and violet articulated concentric line ; aperture subrhom- 

 boidal, sulcate within ; columella arcuate, its base truncate-dentate, 

 and above partly covering the umbilicus. Umbilical area white.
