A few examples taken by the "Thetis" differ from typical 

 specimens from Port Stephens by being paler, with slighter 

 longitudinal sculpture, 'I'hey are 

 also smaller, measuring 12 mm. in 

 length and 4-5 mm. in breadth. 



Owing possibly to worn matetial, 

 the sculpture is not well described in 

 the original diagnosis. I find the 

 entire shell to be girt with flat topped 

 spiral ridges, parted by deep, sharp 

 grooves, about twenty-seven of such 

 are borne by the last, and about 

 twelve by the penultimate, whorls — 

 including three or four on the fasciole. 

 The surface of the elevation is cut 

 into oblique, close-set gemmules. 

 These are repeated within the deep 

 interstice by a minute gemmule 

 thread. The eight whorls counted 

 by Angas include a two-whorled, 

 finely punctate, grooved protoconch. 



From 41-50 fathoms off Cape Three Points.
