BULLIA ALFREDENSIS, new species. 

 Plate 3, fig. 2. 



Shell elongate-conic, cream }^ellow marked with a rust brown 

 band which extends over a little more than the anterior half between 

 the sutures. This band is not of uniform purity but consists of a 

 series of dark and lighter elements which give the whorls the false 

 appearance of having brown ribs. '(Nuclear whorls worn.) Post- 

 nuclear whorls rounded, narrowly, tabulatedly shouldered at the 

 summit, marked by 10 incised spiral striations of which the posterior 

 six are about equally strong and occupy the posterior third of the 

 whorls between the sutures. These are much finer and closer spaced 

 than the other four which divide the remaining space between the 

 sutures into subequal sections. Periphery of the last whorl well 

 rounded. Sutures strongly constricted. Base slightly produced, 

 marked like the anterior two- thirds between the sutures, the incised 

 lines being a little closer on the extreme base than they were on the 

 periphery. Aperture suboval, channeled anteriorly; posterior angle 

 decidedly obtuse; outer lip thin; columella curved, provided with a 

 strong callus which also extends over the parietal wall. 



The type, Cat. No. 187011, U.S.N.M., comes from Port Alfred 

 (Coll. No. 545). It has eight whorls, and measures: Length, 27 mm.; 

 diameter, 9.2 mm. 



Three additional lots from Port Alfred are in the collection of the 

 United States National Museum, as follows: Cat. No. 187012, one 

 specimen (Coll. No. 546); Cat. No. 250445, one specimen (Coll. No. 

 1318); Cat. No. 249736, one specimen (Coll. No. 1008). 



BULLIA ALMO, new species. 

 Plate 35, fig. 4. 



Shell broadly elongate-conic. Nuclear whorls a little more than 

 one, white, well rounded, smooth. Postnuclear whorls light orange, 

 marked with a strong sloping shoulder which extends over the 

 posterior two-fifths of the whorls between the sutures, the anterior 

 limit of the shoulder forming a decided angle. Surface of the shell 

 marked by numerous, slightly retractive axial lines of growth and 

 fine, incised, spiral lines; the latter are chiefly confined to the sloping 

 shoulder, only two or three extend anterior to this. The incised 

 fines on the shoulders increase in number from the early whorls to the 

 last. They are of irregular size and spacing. About a dozen strong 

 ones, and about half as many less strong, occur upon the shoulder of 

 the last turn. Aperture large, channeled anteriorly. Posterior 

 angle acute; outer lip thin; columella sigmoid; parietal wall glazed 

 with a thin callus. 



The type, Cat. No. 250446, U.S.N .M., comes from Port Alfred 

 (Coll. No. 1319). It has 8£ postnuclear whorls, and measures: 

 Length, 22 mm.; diameter, 9 mm. .
