Victorian Marine Mollusca, 139 



The species listed as Mangilia gatliffi, Verco, will also be in- 

 cluded in the genus Aesopiis. 



Genus Zafra, A. Adams i860. 



This contains the small axially plicate species, which we have 

 already listed as Coliimhella atkinsoni, Ten.-Wds. ; C. smithi, 

 Ang. ; C. cominellaeformis, Tate ; and C. remoensis, Gat. and 

 Gab. The last-named species is not a typical form, but at pre- 

 sent we place it in this genus. 



Genus Retizafra, Hedley 1918. 



Retizafra calva, Verco. 



1911. Columhella cclva, Verco. Gat. and Gab., these 



Proc, V. XXIV., p. 194.

 This genus comprises small forms with clathrate sculpture, 

 ajid includes Columhella gemmulifera, Hed., already listed. 



Genus Conorbis, Swainson 1840. 



CoNORBis SARciNULA, Hedley.

 LL, for 1917, p. 80, No. 831. 

 Hah. — Taken off cable to Tasmania, Bass Strait. 

 Ohs. — Size of type: Length 7, breadth 4 mm. 

 Mr. Hedley's excellent description and figure of the species, 

 readily enabled the identification of our shell; his single speci- 

 men was dredged in 111 fathoms 12^ miles due east of Cape 

 Byron. Mr. Hedley and one of us compared the single speci- 

 men got off the cable with the type; they were absolutely the 

 same in size, colour and sculpture, and both fresh shells. We 

 do not agree in the classing of it in either of the genera named, 

 and place it in the genus Conorhis. 



Family TURRIDAE, replaces Pleurotomidae. 



Genus Hemipleurotoma, Cossmann 1889. 



This includes the shell listed as Drillia quoyi, Desmoulins.
