In 100 fathoms 90 miles west of Eucla a large lump of 

 coral was taken, and in a cavity of this when chopped open 

 lay a perfect specimen dead, with a deciduous thin white 

 smooth epidermis, 35 mm. long by 14 mm. broad, somewhat 

 smaller than the type.

A large, thin, brown, polished, elliptical shell. Proto- 

 conch absent, the line of separation thin and jagged ; the 

 exposed pillar very oblique, thick, smooth, and rounded, 

 concealing the projecting hemispherical apex of the shell. 

 Whorls three, shouldered below the suture, at the upper 

 fourth of the intersutural space. Shoulder coronated with 

 tubercles, eleven on a whorl, none on the first whorl, the 

 earlier tubercles pointed, the later becoming broad until about 

 half as wide as the interspaces, shortly pliciform, but ex- 

 panding, and vanishing before reaching the lower suture. 

 Whorls sloping, concavely sub-gradate above the shoulder, 

 sloping slightly convex below. Suture distinct, minutely 

 channelled. Body-whorl large, oval, narrowed anteriorly. 

 Aperture axially narrowly elliptical. Inner lip a thin exten- 

 sive glaze over the whorl ; outer lip immature, thin, uniformly 

 convex, and (as the growth-lines show) curving roundly to a 

 wide, rather shallow, anterior notch. Columella subconcave, 

 three very oblique plaits, the lowest forming the margin of 

 the canal. 



Sculpture. — There are crowded, fine, wavy, spiral lirae, 

 about twenty above the shoulder, less valid over this and soon 

 becoming obsolete below it. Accremental striae granulate 

 these and become ruder towards the aperture. Colour, dark 

 chestnut-brown, obscurely minutely spirally crowdedly necked 

 with white, with scattered darker-brown blotches, the tips of 

 the tubercles a deep blackish-brown. A narrow creamy band, 

 distinct on its under margin, indistinct along its upper border, 

 starts just within the back of the aperture and winds round 

 the body-whorl to the middle of the. outer lip. 



Dimensions. — Length, 16'3 cm., of the aperture 11'3 cm. ; 

 width, 833 cm., of the aperture 4'77 cm.; diameter of the 

 protoconchal base, 18 mm.
