Shell large, solid, lanceolate. Colour buff, with chocolate stains on 

 either side of both sinus and canal, a fainter chocolate band on base. 

 Whorls ten, rounded. Sculpture: — Round-backed prominent ribs, set 

 their breadth apart, twelve on the penultimate, arise below the sutuie 

 and gradually vanish on the base; the spirals are coarse threads which 

 over-ride the ribs and amount to thirty-five on the last whorl, five on the 

 fasciole being small and uniform ; on the periphery several minute threads 

 are intercalated between tlie larger ones ; on the snout are about twelve 

 coarse spaced threads. Aperture fortified by a broad and high varix, 

 expanding into a free edge with a serrate margin ; within the margin are 

 eight entering lyree, the lowest twice as large as the others ; inner lip 

 with a substantial callus ; on the lower part of the columella are two 

 plications ; canal short, open ; sinus deeply incised, sub-ciicular. Length 

 14 mm., breadth 5 mm. 



This species was confused by me with its near ally E. aliceii'. On 

 closer examination that is found to differ by being laigei', proportionately 

 broader, and by having the spiial sculpture more developed, especially 

 on tlie fasciole. 7?. lubiotm occurs in the mud zone, while E. (dicece is 

 apparently confined to the clearest water. Another ally is E. tihtiisicoxtata 

 Smitli, which has less prominent ribs and more even spirals. E. cra8)<llabri(Vi 

 Reeve is a sliorter broader shell than E. lubiusa, with closei- I'ibs and more 

 even spirals. E. glabripllcuta Sowerby is distinguishable from E. labiosa 

 by widei" sf)aced radials, and by the unusually fine and even texture of the 

 spirals. E. cuhiien Hedley has a broadei- shell than htbiosn, witli fewer 

 ribs and more regulaily alternating lai-ge and small spiials.
