A REVISION OF THE AUSTRALIAN TURRIDH—HEDLEY. 223 
the last whorl, and three or four on the upper whorls. Aperture :—Right 
insertion slightly mounting above the plane of the suture; the sinus a 
large U-shaped spout, below which is an incipient varix ; beyond the latter 
the free limb of the outer lip bends inwards; within this lip are sometimes 
a few entering plications ; inner lip a sheet of callus, thin above, but with 
a thickened margin below; canal short, expanding, and open. Length 
9-5 mm., breadth 3°5 mm. 
On first acquaintance I considered this to be a variety of Milodrilla 
tricarinata, but more material convinces me that it is distinct, because of 
a narrower protoconch, and finer, more numerous spirals.

FILOpRILLIA ORNATA sp nov. 
(Plate xlii., fig. 9.) 
Shell small, rather solid, turreted, subcylindrical. Colour uniform buff. 
Whorls rounded, six, inclusive of the bulbous protoconch. Sculpture :— 
The flattened and conspicuous fasciole carries three or four small spiral 
threads; the remaining spirals are sharp cords, narrower than their 
interspaces, larger and wider apart on the periphery, about fifteen on the 
body whorl and five on the penultimate; radial riblets, so faint as to 
scarcely appear in the intercostal furrows, form beads on these spirals; 
these riblets are most developed on the fourth and fifth whorls, and 
vanish gradually on the last whorl. Aperture open, sinus wide and deep ; 
inver lip with a thin callus; canal short and broad. Length 7:5 mm., 
breadth 3 mm.
