at the base. Inner lip a glaze on the body-whoi-1. Colum- 

 ella vei-y long, straight. Basal lip straight, joining the col- 

 umella at a right angle, and the uniformly-curved outer lip 

 at a rounded obtuse angle.

Trophon segmentatus, n. sp. PL xxiv., tig. 3. 



Shell fusiform of 7 whorls, including a protoconch of 

 2 smooth convex whorls, with a deep suture. Spire- whorls 

 boldly angled above the middle, and constricted towards the 

 simple suture. Base gradually contracted to a moder- 

 ately long snout. Aperture roundly oval, opening abruptly 

 in front into a canal of equal length, slightly deviated to the 

 left, and not recurved. Outer lip thin and corrugated ; 

 inner lip a complete, prominent, erect lamella. Sculpture 

 elaborate ; axial laminae, twelve in the penultimate, rather 

 solid, imbricating, coronating the angle with rather long, open 

 tubiform scales, curving up and back, and frilled with re- 

 curved valid scales distributed in spiral rows as though along 

 sjDiral lirae, two in each spire-whorl and ten in the body- 

 whorl, extending over the base, and over the back of the 

 canal. Colour white, with a narrow brown band immediately 

 above the suture, and from behind the aperture round the 

 base to the front part of the labrum. 



Dim>. — Length, 8'5 mm.; of the body-whorl, 4'6 mm.: 

 width, 3*5 mm., excluding the long scales.

Trophon plicilaminatus, n. sp. PI. xxiv., figs. 1 and 2. 

 Shell thin, long, narrow, fusiform, of 8 whorls, includ- 

 ing a protoconch of 2 smooth, convex, prominent whorls. 

 Spire-whorls convex, swollen, and angled above the middle, 

 contracted towards the distinct simple suture. Body-whorl 

 convexly contracted below the angle, then concavely produced 

 into a long, narrow snout. Aperture oval, wider behind ; 

 canal long, narrow, slightly oblique to the left, not recurved, 

 making a faint round angle with the base of the columella. 

 Inner lip a thin applied glaze. Axial lamellse, fifteen in the 

 penultimate, from suture to suture, erect and imbricating, 

 projecting at the angle in long, open tube-like upward-curv-
