A REVISION OF. THE AUSTRALIAN TURRID#—HEDLEY. 331 
meshes are enclosed by radial and spiral cords, with small prickles at the 
point of intersection ; both radials and spirals vary in their development ; 
on the last whorl there may be from nine to twelve radials, and from 
fifteen to eighteen spirals; on the upper whorl there are from three to 
five spirals, the peripheral one dominating. Aperture:—The notch is 
sutural and rather deep; the outer lip is dentate by the projection of the 
spirals; the canal is rather long and straight. Length 5:5 mm., breadth 
2 mm. 
This species approaches the Indian V. asperulata, in which the 
sculpture is much finer. 
Hab. Queensland:—5 to 10 fathoms, Hope Island (type); 5 to 8 
fathoms, Palm Island; 17 to 20 fathoms, Mast Head Island (self). 
Var. PAUCICOSTATA var. nov. 
(Plate liv., fig. 167.) 
With fewer spiral cords than in the typical form, the specimen here 
figured has six radials. 
Hub. Queensland :—Murray Island and Hope Island (self).

Clathurina (Veprecula) vepratica Melvill, 
Proc. Malac. Soc., xii., 1917, p. 140, 
pl. x., fig. 14. 
This is larger than the other Aus- 
tralian species. Dr. J. C. Melvill has 
lately extended the range of it to Japan 
and the Persian Gulf. The citation in 
the original account of this species from 
Torres Straits refers to a specimen of 
V. vacillata. 
Hab. N.S. Wales:— 24 to 100 
fathoms, Wollongong to Port Stephens 
(“‘ Thetis”). Fig. 9.
