 sharp notch between the upper callus and the umbilical lobe, 

 which hides much of the cavity. The marks are small and 

 arrow-headed. 



51. RDFiLABBis, f. 127, Reeve. — Globosa pallida cinereo 

 fasciata, castaneo obscure variegata; spira breviuscula, an- 

 fractibus convexis, callo umbilicali tumido, rubro, umbilicum 

 fere tegenti. — A globose shell, with red columellar callus 

 nearly filling the umbilicus. 



52. TRISERIATA, f. 138, Say. — Globosa, sordide livida, 

 obscure trifasciata, spira paulo elevata, anfractibus convexi- 

 usculis ; columella alba, subaequaliter tumida, umbilicum

 tenuis ; spira elevata, anfractibus rotund is, umbilico angusto, 

 callo spirali fere umbilicum implenti ; columella infra arcuata.

 spiral callus seen behind the columella.

 bilicum anguste callosa, cum callo spirali parvo umbilicali 

 confluent! ; umbilico angustissimo superne angulato. — The 

 peculiarity of this species was not observed till it became too

 thickened columella.
