Probably Doliinn niin-(jliii(liiiii, Pliilippi and />. rcpvci, Hanle}", are 

 related to the species under discussiou but the tignres of those species do 

 not admit of serviceable comparison. 



Luc. — Tlie type specimen was taken by Mr. .1. Bi'azier in mud from 

 13 fathoms off George's Head, Port Jackson. The "Thetis" took it 

 outside the Heads in depths down to 66 fathoms. From Queensland it has 

 been reported from Moreton Bay (Gazelle), Mast Head Lsland (Hedley), 

 Cape Grafton (Roth), and Torres Strait (Haddou).

Compared to the typical form from Sydney, this is a thinner shell, 

 smaller and more oval ; that is witli a higlier spire and a diameter less in 

 proportion to height. 



A specimen trawled January, 1919, in the Uanraki Gulf, by the 

 Municipal Fishing-boat " Cowan " has five whorls, exclusive of the proto- 

 conch, a height of 185 mm., major diameter 132 and a minor diameter of 

 110 mm. 



Loc. — North of Tanranga (Nortli Island), New Zealand.

The picture by Reeve of this species is not satisfactory. By examin- 

 ation of the specimens in the Macleay Museum, I find that the record of 

 Poliuni rJiiiie)i.<-p irom Queensland by Mr. Brazier^ is based on this species. 

 A specimen from Port Stephens corresponds well to Montrouzier's excel- 

 lent figure. The small dints on the ribs are useful specific recognition 

 marks.
