transfer all three to Maculotriton^ as more suitable for their 

 reception than Cantharus. The genus has already been reported 

 from the State as M. hracteatus Hinds.*

 (Plate Ixxxiii., fig.76.)

Shell small, solid, ovate. Whorls six, half of which compose 

 the protoconch. Colour pale buff with a broad orange zone

 beneath the suture. Sculpture: radial riblets are disposed at 

 the rate of about eighteen to a whorl and are crowded towards 

 the aperture, each expands posteriorly to form a subsutural bead- 

 row. Their interstices are crossed by broken spiral furrows at 

 the rate of sixteen to a whorl. Aperture slightly ascending, 

 varix solid and projecting, outer lip with four interior denticles, 

 inner with a small tubercle at either end. Length, 5; breadth,

Mr. G. C. Robson, of the Natural History Museum, London, 

 to whom I referred the form here described, writes that "iT. 

 ccelata is three times larger, and has more transverse ribs, but is 

 otherwise very near your species; and the latter is probably the 

 young." N. ccelata has not previously been recorded from Aus- 

 tralia.
