PLEUROTOMID, 43 
P. zealandica, Smith, Ann. Nat. Hist., 1877, p. 492. Shell 
strong ovato-turreted, flesh-white ; spire acuminate, tapering gradually, 
apex brownish ; whorls ro, first 2% polished, vitreous, convex, the rest 
slightly convex, keeled above with the slope level (the tabulations strongly 
radiately striated), impressed with 2—3 sulci (the upper large, obliquely 
strongly striated). Body whorls large somewhat inflated, contracted to- 
wards the base ; ornamented with about twelve strong sulci, longitudinally 
striated ; aperture dusky, large; columella darkish, arched in the mid- 
dle, oblique below, the lip forming a slightly recurved, short canal ; 
caudal keel small, set round with dusky ; slit rather broad, not deep, 
situated slightly above the middle of the lip. (Smith). 
Length ‘9 ; diameter, *36 inch. 
Remarkable for the tabulated whorls, the tabulations being very 
strongly radiately striated, and sometimes furnished with a spiral liration, 
and the conspicuous sulcations encircling the body-whorl. The slit in 
the labrum is situated just below the broad furrow which grooves the 
upper parts of the whorls. 
P. antipodum, Smith; Ann. Nat. Hist., gth ser., xix, p. 491. 
Shell small, fusiform, pale flesh-brown, with transverse white keels, and 
between the keels very finely longitudinally lirated ; whorls 7%, the 
first 2% polished, smooth, the following four above at the suture 
doubly keeled, and slightly below the middle another, distant, larger 
one. Body whorl large, contracted towards the base, with about nine 
principal and about six smaller keels; aperture oblong contracted 
below, smooth inside, about half the entire length; lip thin, margin 
hardly crenulated, above the keel a broad but shallow incision ; 
columella tortuous, callous, shining ; canal short, re-curved. 
Length, *4; diam., ‘16 inch. (Smith.) 
Perhaps the same as the next species. 
P. albula, Hutton. C..M. p. 12. Spire acute ; whorls spirally 
grooved, and with a central prominent spiral rib ; smooth ; aperture 
oblong, canal very short ; body whorl as long as the spire. Ochraceous 
white ; apex and columella white. 
Length, 35 ; breadth, 15 ; angle of spire, 30°. 
Stewart Island to Auckland. 
In this species there are 74% whorls, and the grooves are finely 
transversely striated. 
Genus, DRILLIA—Gray. 
Tentacles approximated ; eyes at their outer side, near the tip. 
Shell turreted, spire raised; aperture oval; canal short, re-curved ; 
inner lip thickened ; outer lip inflexed, with a deep posterior sinus, and 
a small sinus at the fore part ; operculum ovate, acute; nucleus 
apical.
