(IMate xlviii., Hg. S4.) 



Shell elongate bicoiiic, a flat sloping shoulder and a perpendicular 

 pei-iphery giving it a pagodiform aspect. Cohjur buff, sometimes with 

 pale yellow bauds on the last wliorl, on the outer lip lemon yellow, 

 sometimes with chocolate on the pillai-. Whoi'ls seven, including the 

 protoconch, which consists of a small rounded upstanding whorl, followed 

 by two sharply keeled whorls. Sculpture : — On the last whorl are twenty- 

 two spirals, of which three on the periphery are most prominent; the 

 radials are not consecutive, they increase from nine on the early whorls 

 to fifteen on the last; they are slight near the suture, prominent on the 

 periphery, and absent on the base ; they are over-ridden by the spirals, 

 which form deep meshes on the periphery, a double row on the last whorl 

 and a single one above. Aperture : — The prominent varix spreads a broad 

 tooth-edged lip over the mouth; it is excavated above in a spout-like 

 sinus; at the lip insertion is a massive coloured tubercle ; within tlie lip 

 are four or five entering plications ; across the columella are two transverse 

 plaits; canal short. Length 5 mm., breadth 2 2 mm. 



This species is related to E. elegans, but that is smaller, more slender, 

 with an unarmed columella, and lattice sculpture on the periphery.

EtRKMA SPARUI.A sp. 7WV. 



(Plate xlviii., fig. 85.) 



Shell large, broad, and comparatively thin, conic-fusiform, contracted 

 at the base, turreted, last whorl about as long as the spire. Whorls eight, 

 including the protoconch, which is mucronate of two whorls, the first flat- 

 topped, the next keeled. Suture canaliculate. Colour buff, finely speckled 

 with chestnut, the spots larger and darker near the suture, with a pale 

 zone below the periphery. Sculpture: — The ribs a^'e low, round-backed, 

 sharply angled at the shoulder, vanishing on the base and round the 

 fasciole area, spaced at twelve to a whorl ; the whole shell is wrapped m 

 sharp narrow threads, which swell on crossing a rib and shrink in the 

 interval ; they are parted by furrows deeper than wide, and support 

 microscopic close-set transverse beads; on tlie penultimate there are 

 about twenty-three and on the last whorl about sixty of these cords. 

 Aperture : — The variceal ridge is tall and narrow, from which extends 

 squarely a free limb dentate at the edge and slightly ribbed within ; sinus 

 rather deep and C-shaped ; a callus tubercle at the right insertion is 

 tricuspid ; on the inner lip the callous sheet thins off to a fine edge, and 

 has a few faint plications anteriorly; canal short, broad, and recurved. 

 Length 17 mm., breadth 7-5 mm.
