BULLIA AEPYNOTA, new species. 



Plate 35, fig. 5. 



Shell elongate-conic, light yellow. Nuclear whorls decollated. 

 Postnuclear whorls strongly, tabulatedly shouldered at the summit 

 after the second turn. First two turns feebly rounded, the remain- 

 der slightly concave in the middle between the sutures. Surface 

 marked by feeble, retractive lines of growth and well incised spiral 

 lines, which appear to be confined to the anterior two-thirds of the 

 whorls between the sutures. Sutures strongly marked by the flat- 

 tened shoulder at the summit. Periphery of the last whorl well 

 rounded. Base moderately long, rounded, marked by a few incised 

 spiral lines. Aperture with the posterior angle obtuse, channeled 

 anteriorly; outer lip thin; columella glazed with a thin callus. 



The type, Cat. No. 250443, U.S.N.M., comes from Port Alfred 

 (Coll. No. 1316). It has seven postnuclear whorls and measures: 

 Length, 19 mm.; diameter, 6.5 mm. 



BULLIA LARA, new species. 

 Plate 38, fig. 3. 



Shell large, flesh colored. Nuclear whorls decollated. Postnuclear 

 whorls well rounded, with a rounded shoulder at the summit, marked 

 between the sutures by equal and equally spaced, incised, spiral lines, 

 which are strongest at the anterior two- thirds. Sutures constricted, 

 Aperture large, channeled anteriorly. Posterior angle obtuse; outer 

 lip thin; columella stout and curved; parietal wall glazed with a 

 thin callus. 



The type, Cat. No. 249737, U.S.N.M., comes from Port Alfred 

 (Coll. No. 1009). It has eight postnuclear whorls and measures: 

 Length, 38 mm.; diameter, 19 mm. Cat. No. 250443a another speci- 

 men from the same place (Cat. No. 1316<z). This specimen somewhat 

 resembles Bullia tenuis Reeve, but differs from it by being much more 

 elongated — that is, less broadly conic. 



BULLIA TENUIS Reeve. 



Cat. No. 16826, U.S.N.M., two specimens from Cape of Good Hope. 

 Cat, No. 186766, U.S.N.M., two from Port Alfred (Coll. No. 127).
