examples by being broader, with more numerous ribs, and being speckled 
with brown. In these features it agrees with Lifuan material labelled 
“var. delta” by Hervier.??

outer Barrier Reef, about 8. lat. 14 (self). 
EPREMA LABIOSA sp. 10. 
Clathurella crassilabrum Brazier, Proc. Linn. Soc. Neue 1., 1876, p. 156 
(not Plewrotoma Ceiluontl Reeve, Conch. Icon., La xiv, fig. 118). 
Glyphostoma alice Hedley, Proc. Linn. Soc. N.S.W., xxxiy., 1909, p. 454, 
pl. xliii., fig. 88 (not G. alice Melvill and Standen). 
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 suture 
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 the 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 lyre, 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-cireular. Length 
14 mm., breadth 5 mm. 
This species was confused by me with its near ally H. alicew. On 
closer examination that is found to differ by being larger, proportionately 
broader, and by having the spiral sculpture more developed, especially 
on the fasciole. #H. labiosu occurs in the mud zone, while H. alice is 
apparently confined to the clearest water. Another ally is W. obtusicostutu 
Smith, which has less prominent ribs and more even spirals. H.crassilabrum 
Reeve is a shorter broader shell than H. labiosa, with closer ribs and more 
even spirals. H. glabriplicata Sowerby is distinguishable from W. labios 
by wider spaced radials, and by the unusually fine and even texture of the 
spirals. H. culmea Hedley has a broader shell than labiosa, with fewer 
ribs and more regularly alternating large and small spirals.
