310 STUDIES ON AUSTRALIAN MOLLUSCA, xi., 



Thesaurus, f. 636, Pres. G. F. Angas." An examination of this 

 induces me to add C. tasmanice to the already extensive synonymy 

 of the common tropical C. magus Linne. Sowerby's locality is, of 

 course, false. 



Drillia vexillum Reeve. 



Pleurotoma vexillum Reeve, Conch. Icon, ii., 1845, PI. xxix., fig. 

 264 ; Id,, Angas, Proc Zool. Soc, 1867, p. 203. 



This was reported by Angas from Middle Harbour, near Sydney. 

 In the British Museum, a specimen labelled PI. vexillum, Rve., is 

 marked "St. Vincent's, West Indies." This, and the fact that no 

 other observer has found it in Australia, cause the record of Angas 

 to be distrusted. 



Mangelia mitralis Adams and Angas. 



(Plate xix., fig. 75.) 

 Bela mitralis Adams and Angas, Proc. Zool. Soc, 1863, p. 420. 

 The present figure is derived from one of two in the British 

 Museum, marked as types of Bela mitralis. 



Mangelia australis Adams and Angas. 

 (Plate xix., fig. 76.) 

 Bela australis Adams and Angas, Proc. Zool. Soc, 1863, p. 420 ; 

 Id., Pritchard and Gatliff, Proc Roy. Soc. Vict., xii., 1900, p. 173 ; 

 Id., Verco., Trans. Roy. Soc. S.A., xxxiii., 1909, p. 311. 



M. australis has not been previously figured. The type in the 

 British Museum is here illustrated. By Pritchard and Gatliff, it is 

 united to M. mitralis, and Verco further links it to M. tasmanica 

 and to M. jacks onensis. 



Mangelia nassoides Reeve. 



Pleurotoma nassoides Reeve, Conch. Icon., ii., 1845, PI. xxix., 

 fig. 259. 



Clathurella zonulata Angas, Proc. Zool. Soc, 1867, p. 113, PI 

 xiii., fig. 17. 



In the British Museum are two specimens marked, "Clathurella 

 zonulata Angas. Type, Pres. G. F. Angas." Beneath this tablet
