(Coll. No. 1275). Cat. No. 250401, two specimens (Coll. No. 1274). 

 Cat. No. 252277, 10 specimens (Coll. No. 1586). Thirty-live speci-

ALVANIA FARQUHARI Smith. 

 Plate 5, fig. 5. 



Cat. No. 187057, U.S.N.M., two specimens from Port Alfred (Coil. 

 No. 595). Cat. No. 227740, U.S.N.M., three specimens from the same 

 locality (Coll. No. 835). In addition to these, I have seen 40 speci- 

 mens in Colonel Turton's collection (Coll. No. 1586). 



ALVANIA ALFREDENSIS, new species. 



Plate 21, fig. 8. 



Shell elongate-conic, white. The nucleus consists of a single turn 

 which appears to be smooth. The succeeding turn is well rounded, 

 the next, strongly shouldered on the middle, while the last is slightly 

 concave immediately below the suture, and the rest well rounded. 

 The second whorl is marked with six slender spiral cords, which are 

 about as wide as the spaces that separate them. On the following 

 tarn a broad cord appears at the appressed summit and four slender 

 ones on the space between the summit and the angulated shoulder; the 

 shoulder itself being marked by a stronger spiral cord, while the space 

 anterior to it bears three about as strong as the last. On the penulti- 

 mate whorl 1 2, equal and equally spaced, spiral cords appear between the 

 summit and the posterior termination of the outer lip, and six upon 

 the base. These cords are equal and equally spaced and are about as 

 wide as the spaces that separate them. Aperture apparently oval; 

 outer lip fractured; inner lip rather thick, almost vertical, and 

 somewhat reflected over the base; parietal wall covered by a 

 moderately thick callus. 



The type, Cat. No. 250392, U.S.N.M., comes from Port Alfred 

 (Coll. No. 1265). It has four postnuclear whorls, and measures: 

 Length, 1.5 mm.; diameter, 0.6 mm. 



ALVANIA ALMO, new species. 



Plate 21, fig. 7. 



Shell elongate-ovate, thin, semitranslucent. Nuclear whorls one 

 and a half, well rounded, smooth. Postnuclear turns marked by two 

 strong, spiral keels, the first of which is situated about two-thirds of 

 the distance between the summit and the suture anterior to the sum- 

 mit, while the second is about one-fifth of the distance above the 

 suture, leaving the space between the two, equal to about two-fifths 

 of the distance. The space between the summit and the first keel, 

 forms a strongly sloping shoulder, while the space between the two
