TURRIDRUPA PERTINAX Hedley. 
(Plate xliii., fig. 15.) 
Shell small, cylindro-fusiform, contracted at the base. Colour pale 
buff, darker on the base and the columella. Whoris eight, including the 
protoconch. Suture deeply channelled. Sculpture :—On the last whorl 
there is a prominent keel on the shoulder, followed anteriorly by seven 
evenly spaced and gradually diminishing spirals; above the keel is a 
broad fasciole, crossed by fine crescentic riblets and bounded by a small 
spiral; on the upper whorls three spirals alone persist, the median being 
prominent. Aperture narrow; sinus wide and rather short; canal short 
and a little reflected; columella straight, with a thickened margin. 
Length 5 mm., breadth 1:5 mm. : 
This species may be distinguished from its associate, 7’. commentica, 
by less prominent keels and more cylindrical form. 
Hub. Queensland :—5 to 10 fathoms, Hope Islands (type); 15 
fathoms, Palm Island (self); 20 fathoms, between Cairns Reef and 
Endeavour Reef (McCulloch); off Cape Sidmonth (Henn); Darnley Island 
(Brazier). Papua:—Katow (Brazier). 
Herpetra Hedley. 
Epideira Hedley, Journ. Roy. Soc. N.S.W., li, 1918, p.M 79. Type 
Clavatula striata Gray, 1827. 
Shell solid, ovate-acuminate, last whorl about as long as the spire. 
Sculpture :—A bead-row along the fasciole, and frequently another along 
the suture, separated by a broad furrow ; the base is cancellate with radial 
and revolving cords. Protoconch smaller and less elevated than that of 
Turris or Inquisitor, of two smooth turbinate whorls, set a little obliquely, 
and from one aspect appearing bulbous. Fasciole ascending the spire in 
the middle of each whorl. Notch broad and shallow. Outer lip not in- 
flected; canal very short. Pillar a little twisted. Operculum of the turrid 
type. 
In general appearance this genus approaches Clavutulu, to which 
indeed the type species was originally assigned. The operculum here 
noted (Plate xliii., fig. 20) in the case of H. striatu, and previously 
deseribed by Sir J. Verco for H. perksi and H. quoy!, however excludes it. 
In the pattern of the sculpture Gemmula has some likeness to Hpideira, 
but the post-nepionic sculpture separates it. A near relation is Bathytoma, 
from which Hpideira is separable by sculpture, shorter canal, taller spire, 
more numerous whorls, and straighter columella. 
Hpideira seems to be represented in New Zealand by Plewotoma rosea 
Quoy and Gaimard. 
EPIDEIRA GABENSIS sp. 100. 
(Plate xliii., fig. 16.) 
Shell rather thin; ovate-lanceolate. Colour buff, variegated with 
white clouds about the periphery, and chestnut spots on the suture. 
Whorls seven, including a smooth two-whorled protoconch. Suture
