Daphrella vestalis, Hedley, Memoirs Austr. Mus., iv., part 
6, 1903, p. 890, fig. 105. ‘Taken in 24 and 52 fathoms, off Port 
Stephens and Botany Bay.” 
Dredged in 104 fathoms 35 miles south-west of Nep- 
tune Islands, 2 good dead, 1 fragment. Identified by Hedley 
from his type. 
As this shell has its sinus at the carina and has a short 
canal, it has been placed in Hemipleurotoma. 
. i mayi, n. sp. Pl. xxy,, fig. 2. BAL 
Shell thin, oval, white, of 4 whorls besides a brown pro- 
toconch of 2 whorls, which are convex, apparently smooth, 
but under the microscope very finely spirally lirate and in- 
terstitially punctate. Spire-whorls convex medially sharply 
angulate with a cord, base contracted, and forming a moder- 
ately long canal, which is slightly curved to the left. Sutures 
distinct, finely canaliculate. | Aperture obliquely oval ; 
outer lip thin, simple, ridged outside by the spirals, with 
an obtuse shallow, wide triangular sinus at the angulation. 
Sculpture: above the angle are three spirals in each whorl, 
and one below it; in the body-whorl are eighteen, subdistant 
just below the angle, crowded towards the canal. Very fine 
axials, about 42 in the penultimate, run obliquely back from 
the suture to the angle, and then at an obtuse angle ob- 
liquely forward to the suture. 
Dim.—Length, 46 mm.; of the body-whorl, 3°1 mm. ; 
width, 2°4 mm. 
Locality.—Type in 104 fathoms, 35 miles south-west of 
Neptune Islands, with 2 others dead. 
Diagnosis.—D. vestalis, Hedley, though described as 
having a smooth protoconch, has it punctate spirally striate, 
differs in being larger, more solid, more obese, not so sharply 
angled, and in having a shorter canal, and fewer and more 
solid axials. 
Variations.—One example has only one spiral above its 
very sharp angle, namely, a bold cord just below the suture, 
making this more channelled; and only one below the angle 
just above the suture in the second and third whorls, and 
seven in the body-whorl.
