45. Seila Chathamensis, n.sp. PL III, Fig. 45, 

 Shell small, elevated conic, solid. Sculpture : first whorl smooth, 

 the succeeding two with two cingula, the upper of which is incon- 

 spicuous, but the lower one is thick and prominent ; the following five 

 whorls have three rounded cingula, then there are four on the next 

 volutions, and six on the last whorl, the lowest being upon the base ; 

 the uppermost cingulum on the last whorl is usually grooved or 

 divided into two narrow cingula, increasing their number to seven. 

 The interspaces are densely and finely longitudinally striated by 

 growth-lines. Colour fulvous. Spire high conical, much higher than 

 the aperture ; outlines slightly concave below the first two whorls, 

 nearly straight further down. Protoconch small, depressed, of one 

 smooth whorl only. Whorls about 13, regularly increasing, the 

 second and third convex, the others flattish ; base flat, concave round 

 the canal. Suture not much impressed. Aperture vertical, sub- 

 quadrangular, produced below into a very short and open canal, which 

 is slightly turned to the left. Outer lip denticulated on the outside 

 by spiral sculpture, smooth inside ; basal lip nearly straight. Columella 

 arcuate, bent over at a blunt angle toward the canal. Diam. 3-2,

 following volutions with three narrow and rather sharp spiral keels, 

 the upper two closer together, last whorl with five keels, the lowest 

 of which is upon the base ; interstices having fine, dense, straight 

 growth-lines, sometimes oblique near the suture. Spire much higher 

 than the aperture ; outlines straight. Protoconch globular, of one and 

 a half smooth whorls, the first bulbose, of greater diameter than the 

 next few whorls. Whorls about 14, slowly and regularly increasing, 

 flat ; base slightly concave. Suture very little impressed. Aperture 

 subquadrangular, produced below into a short and open canal. Outer 

 lip sinuated on the outside ; lower lip horizontal, slightly ascending

 whorls are smooth, the succeeding ones having three prominent, 

 unequal, equidistant, and flat cingula, the uppermost narrower, lower, 

 close to the suture ; the last whorl has a fourth cingulum towards the 

 base, but quite close to the upper one; indistinct axial riblets and fine
