as denticles. Aperture unfinished, free. Height O'G mm.; 

 major diam. 1-.3 mm.; minor diam. 0*9 mm. 



Abundant in 17-20 fathoms off Mast Head. 



Judging from literature, this species appears to resemble the 

 the Sicilian 0. zanclea Philippi, from which the size, sculpture 

 and elevation of the spire separate it. 



Daphnella excavata Gatliff.

The occurrence of a shell recently described from Victoria was 

 unexpected, but a good series taken in 17-20 fathoms off Mast 

 Head corresponds exactly to authentic examples kindly supplied 

 by Mr. J. H. Gatliff. This extension of range suggests that it 

 may in future be detected in New South Wales. The species 

 somewhat resembles Glathurella hirsuta de Folin, in miniature. 



MiTRA MiTRA Linne. 



Voluta mitra var. ejyiscojoalis Linne, Syst. Nat. x. 1758, p. 732. 



A single worn example from the beach probably represents the 

 southern limit of the shell. Linne compounded his species of 

 two " varieties," episcopalis and papalis. It seems to me, but 

 not to my predecessors, that when papalis was withdrawn as a 

 separate species, the specific mitra reverted to the residual. 



An addition to Australia is Mitra zephyrina Sowerby,"^' of 

 which I dredged a fragmentary specimen in 17-20 fathoms. 



Digressing from the Capricornian fauna, this opportunity may 

 be taken of recording another Mitra new to Australia, M. hern- 

 hardina Bolten, which I gathered at Green Island, off Cairns. 

 It was named in the rare ' Museum Boltenianum'f from a figure 

 by Chemnitz. I Thirteen years afterwards Lamarck established, § 

 on the same figure, his Mitra mui'icidata, a name by which the 

 species is generally known.
