 effusion of its fellow, while the substance is more pellucid 

 and the color clear straw. Both are more or less apically

3. E. LANCEOLATA (Pfeiffer). 



Shell imperforate, turrited, rather solid, longitudinally 

 subarcuate-striate, diaphanous, whitish straw-colored; spire 

 lengthened, rather acute ; suture light, crenulate. Whorls 13, 

 nearly flat, the last forming two-sevenths the total length, 

 slightly tapering basally. Columella somewhat twisted above, 

 then straightened. Aperture little oblique, acuminate-oval, 

 subangulate basally; peristome simple, straight, the columel- 

 lar margin very narrowly reflexed. Length 52, diam. 14, 

 aperture 15x7 mm. (P/r.).

Melvill and Ponsonby include Bulimus micans Pfr. as a 

 synonym of lanceolata. The original description follows: 

 Bulimus micans. Shell imperforate, turrited, rather thin, 

 closely plicate-striate and obsoletely a little decussate, silky, 

 tawny-waxen. Spire regularly tapering, the apex rather ob- 

 tuse, suture subcrenate. Whorls 10 to 11, flattened, the last 

 not a third the total length, subangular in the middle. Colu- 

 mella vertical. Aperture oblique, elliptical-oblong, peristome 

 simple, the right margin straight; columellar margin shortly 

 reflexed, adnate, its junction with the basal margin suban- 

 gular. Length 36, diam. 9, aperture 11x4.5 mm. In the re- 

 gion of Natal (Pfr.). 



This form, like lanceolata, was described from specimens 

 collected by Plant, and in the Cuming collection.
