radials on the peripheral area enclose large meshes; on the upper whorls 
are from two to four spirals. Aperture open and toothless; varix much 
thicker than the ribs; sinus very small; canal short and open. Length 
6 mm., breadth 2 mm. 
In size and general appearance this is like P. modesta, for which it 
has been mistaken P. imayanu is a slightly narrower shell, with more 
numerous and much more slender spirals and radials. Where an inter- 
stitial thread has not interfered, the basal furrow of mayana is a ready 
recognition mark. P. modesta does not occur in Tasmania. Compared 
with P. tincta the Tasmanian shell is smaller, slighter, thinner, and more 
delicately sculptured.

As is frequently the case in this genus, this species has a light and a 
dark colour dimorphism. A brown specimen in the British Museum, 
presented by G. F. Angas, is marked there as the type.

PSEUDODAPHNELLA OLIGOINA sp. 10v. 
(Plate lv., fig. 184.) 
Shell of medium size, rather thin, lanceolate, turreted, with sloping 
shoulder, perpendicular periphery, and excavate base. Colour uniform pale 
buff. Whorls seven, including a two-whorled protoconch. Sculpture :— 
Radials discontinuous from whorl] to whorl, feeble and oblique on the 
shoulder, prominent and perpendicular on the peripheral area, and 
traversing the basal excavation, widely spaced, ten on the last whorl ; 
spirals slighter than the radials; on the fasciole area of the last whorl 
are three faint and narrow threads; from the shoulder to the basal angle 
are five cords, which over-ride the ribs and thus enclose a series of oblong 
and nearly uniform meshes; on the snout are six crowded and progressively 
diminishing beaded spirals; the upper whorls carry four spirals; within 
the meshes are fine radial strize; the basal furrow is spaced as if a spiral
