(Plate xlvi., figs. 56, 57.) 



Shell solid, biconical, slightl}- constricted around the upper part of 

 each whorl. Whorls nine. 'Coloui' laveudei'-gray, with a broad peripheial 

 band of buff descending the spiie, and on the last whorl underlined by a 

 single or double chocolate line ; lip buff ; interior ochraceous brown. 

 Protoconch of two small helicoid whorls. Sculpture : — The first whorl is 

 keeled, and developes small radial ribs; on subsequent whorls the ribs 

 amount to about ten, not continuous from one whorl to the next, bent, 

 and thickened on the shoulder, thence quickly tapering to the suture, 

 continuing in the opposite direction to the base of the last whorl ; the 

 whole shell is over-run by microscopic spiral threads, alternately larger 

 and smaller. Aperture : — The mouth is narrow, oblong, protected by a 

 stout varix which ascends the previous whorl, and in which is excavated 

 a shallow semicircular sinus ; the lip has a very narrow free margin, 

 within which are about eight small inconspicuous teeth ; the columella is 

 overlaid by a thick callus sheet with a definite mai'gin, across it extend 

 ten plications; canal a mere notch. Length 12 mm., breadth 4-5 mm. 



This is related to the New Caledonian E. (jnestieri, but differs in 

 colour, the general tone being slate, not brown ; in being more slender, 

 and having the ribs further apart. There is a general resemblance to 

 E. reticidata, but E. arenivaga is smaller, with fewer and more widelv 

 spaced ribs. Both extremities of aroiivaga taper more, and the body 

 whorl is proportionately smaller. 



Hah. Queensland : — Cape Flattery (type), several specimens crawling 

 in pools and over wet sand north of the headland ; bar of Annam Rivei' 

 (self) ; Cape York (Brazier).
