ETREMA ORIRUPA sp. nov. 
(Plate xlvii., fig. 82.) 
Shell small, rather solid, lanceolate, contracted at sutures, and 
excavate at the base. Colour uniform pale cinnamon, protoconch white, 
interior of aperture rufous to orange-buff. Whorls seven, including the 
protoconch. Sculpture :—The ribs are prominent, round-backed, parted by 
hollow interstices, continuing obliquely up the spire, gradually vanishing 
on the base, and set nine to a whorl; ten main spiral cords encircle the 
body whorl, of which three ascend to the antepenultimate; these ride 
high over the ribs and bridge the interstices; a minute thread is inter- 
calated between the wider spirals; these spirals are beset with sharp close 
grains, which give a harsh touch to the shell. Aperture oblong, rather 
narrow, protected by a prominent and massive varix; sinus a slight 
insinuation; canal short and broad; within the outer lip are five 
denticules, and two obscure folds cross the inner lip. Length 6 mm., 
breadth 2°5 mm.
