DAPHNELLA SIGMASTOMA sp. nov. 
(Plate liv., figs. 163, 164.) 
Clathurella arctatu Brazier, Proc. Linn. Soc. N.S.W., i., 1876, p. 294 (not 
Pleurotoma arctuta Reeve, Conch. Icon., i., 1845, pl. xxxii., fig. 294). 
Shell small, elongate-fusiform. Colour unitorm pale yellow, except 
the apex, which is buff. Whorls rounded, ten, including those of the elevated 
protoconch. Sculpture:—The fasciole is narrow, excavate, and crossed 
by close-set scales; the radials are arcuate round-backed riblets, parted 
by interstices of equal breadth, fading out on the base, absent behind the 
varix, amounting to thirteen on the antepenultimate; the spirals are close 
narrow threads, alternating in size on the peripheral area, and over-riding 
the riblets; on the last whorl there are twenty-five, of which ten ascend 
the penultimate. Aperture fortified by a broad and high varix, from 
which a free limb reaches across the mouth, reducing the width of the 
aperture. The sinus is a long and narrow fold. Within the lip and 
beneath the sinus are two small denticules. Columella perpendicular ; 
canal short and wide. Length 8:5 mm., breadth 3 mm. 
Hub. Queensland :—15 fathoms, Palm Island (type); 5 to 10 fathoms, 
Hope Island (self) ; 4 to 14 fathoms, Albany Passage (self); 20 fathoms, 
Endeavour Reef (McCulloch); 20 fathoms, Darnley Island (Brazier). 
The group to which this and D. cestrwm belong ave separated from 
typical Daphnellu by slender form, prominent ribs and varix. Clathurella 
papuensis Tapparone Canefri,%3 which I only know from the figure, is 
perhaps related.
