This shell was, in the above description, reported by Adams as 

 having been dredged by Mr. Jukes in 8 fathoms off Sir Charles 

 Hardy's Islands, North Queensland. Such a circumstantial 

 statement invites confidence, which in this cases is undeserved. 



Angas continued the tale by announcing G. sulcosa from New 

 South Wales.f Then Tenison-Woods traced it to Tasmania,]: 

 and Pritchard and Gatliff to Victoria.§ 



In correction, Tate and May refer the Tasraanian shell to 

 Gibbida picturala Adams & Angas;|| while Verco identified the 

 Victorian one as Gibbula lehmanni Menke.1T Which shell from 

 New South Wales was mistaken by Angas for G. sulcosa is not 

 known to me.
