A REVISION OF THE AUSTRALIAN TURRID®—HEDLEY. 355 
EUCYCLOTOMA CARINULATA Sowverbie. 
Pleurotoma carinulata Souverbie, Journ. de Conch., xxiii., 1875, p. 289, 
pl. xiii, fig. 6. Td. Boettger, Nachr. Malak. Gesell., 1895, p. 62. 
From the figure this species seems related to fusiformis Garrett and 
varicifer Pease. Hitherto it has only been recorded from New Caledonia.

Palm Island; 17 to 20 fathoms, Mast Head Island (self); Eclipse Island

EUCYCLOTOMA NOBILIS sp. nov. 
(Plate lvi., figs. 194, 195.) 
Shell large for the genus, lanceolate, rather solid. Colour crystalline 
white, splashed irregularly with orange buff; nucleus buff. Besides a 
two-whorled mucronate nucleus there are about seven whorls which wind 
obliquely and are girt with solid projecting keels. The turreted spire is 
a little longer than the last whorl. Sculpture:—On the last whorl are 
four nearly equal girdles; the second and fourth diminish as they ascend, 
and vanish in a thread two whorls above; the keel forming the basal 
angle just emerges above the suture on the upper whorls; close set 
perpendicular riblets bead the keels at the point of intersection, and their 
interstices are again traversed by smaller spiral threads; on the snout 
are half-a-dozen spirals; one specimen has a perfect varix half a whorl 
behind the mouth; the nucleus has close spiral threads reticulated by 
finer radials. Aperture :—Outer lip flared, its edge dentate by the girdle 
ends, and roughened by intermediate wrinkles; sinus subsutural, ovate, 
contracted at the entrance; canal short and bent; columella excavate 
above and twisted below; inner lip represented by a thin film of callus. 
Length 16 mm., breadth 7 mm. 
This comes nearest to H. bicurinata,4 from the Gilbert Archipelago, 
but our shell at a corresponding length has three keels instead of two,
