464 GASTROPODA. [Pectinibraiwhia. 



Shell moderately large, ovoid, the spire produced, porcellanous, 

 fairly solid, columella with 4 plaits. Sculpture formed by fine growth- 

 lines only, sometimes with fine irregular plications below the suture 

 on the last two whorls. Colour light yellow or white, the labial varix 

 pure-white. Spire conoidal, obtuse, half the height of the aperture, 

 somewhat scalar ; outlines nearly straight. Protoconch small, broadly 

 convex. Whorls 5, the last very high, convex, much impressed along 

 the suture ; base narrowed. Suture indistinct, lightly margined 

 above. Aperture high and narrow above, somewhat widened below, 

 channelled above, the channel cutting into the outer lip, broadly 

 truncated and lightly notched below. Outer lip vertical, thick, and 

 rounded, with a prominent smooth varix extending along the basal 

 sinus and running above to the middle of the penultimate whorl, 

 smooth within. Columella oblique, straight, broadly rounded, with 

 4 strong plaits, the first transverse, the lower three oblique, the lower 

 two very close together. Inner lip rather thick, spreading broadly 

 over the lightly concave parietal wall and the body, with an elongated 

 tubercle outside the channel. 



Diameter, 7-5 mm. ; height, 13 mm. 



Animal unknown. 



Type in the Mus. Hist. Nat., Geneva. 



Hob. Auckland to Cook Strait ; apparently a rare shell. Also

Margindla (Glabdla) parvistriata, Suter, P. Mai. S., viii, 183, pi. 7, f. 13. 



Shell very small, oviform, semitransparent, dull, white, axially 

 finely striated, with a shoit spire. Sculpture consisting of minute 

 close and straight axial striae, continuous over the spire to the body- 

 whorl. Colour white or yellowish-white. Spire short, conoidal, with 

 a blunt apex, its height about one-fifth that of the aperture. Proto- 

 conch smooth, broadly convex. Whorls 3, flat on the spire, body- 

 whorl high, moderately convex, slightly narrowed towards the base. 

 Suture indistinct. Aperture high and narrow, a little wider below, 

 subchannelled above, roundly truncated at the base. Outer lip lightly 

 convex, vertical, a little retrocurrent toward the suture, thickened 

 and rounded, smooth inside, with an outer varix extending a short 

 way up the spire and across the basal margin. Columella a little 

 oblique, with 4 oblique nearly equidistant strong plaits. Inner lip 

 broad and thin, distinct only outside the columella ; parietal wall 

 lightly convex. 



Diameter, 1-7 mm. ; height, 3-1 mm. 



Animal unknown.
