Maze, to whom we owe figures of this species, states that 

 Marie found a specimen without dark streaks (fig. 40). I 

 have not seen the species, which appears to be related to 

 V. semitarum. 



74. V. INTERRUPTA ( Shuttlewortli) . PI. 19, fig. 39. 



Shell fusiform, 'thin, very smooth, and glossy, corneous, or- 

 namented with rather wide and unevenly spaced reddish- 

 chestnut streaks, on the last whorl intersected at the peri- 

 phery by a conspicuous whitish zone, and another narrower 

 one on the base. Spire somewhat acuminate, the apex very 

 obtuse. Whorls TI/O, a little convex, the last three-sevenths 

 the total length ; suture narrowly margined, slightly plicate. 

 Aperture narrow, acuminately semi-oblong; peristome sim- 

 ple, acute, the right margin inconspicuously arcuate; colu- 

 mella oblique, very deeply arcuate, truncate at the base. 

 Length 27, diam. 9, aperture 11x4 mm. (Shuttl.}

The embryonic shell is pupiform and consists of 3 smooth 

 whorls, terminating with a brown streak and varix-line. Sub- 

 sequent whorls have fine, inconspicuous growth ripples be- 

 tween the varices. This fine species resembles V. gldbra in 

 sculpture, but differs by its slender, attenuate spire, with 

 embryonic shell of a very different shape. 



Group of V. glabra. 



The oblong shell is rather large, Oleacina-like, smooth and 

 glossy, with an obtuse conic embryonic shell of 3i/o whorls. 

 This form resembles Oleacina in general appearance and in 

 the conic embryonic shell, but it also seems closely related 

 to V. interrupta, which by its pupiform embryonic whorls re-
