Bednall some years back as Troclius odontis? "Wood. I think 

 that Mr. Angas must have mixed up two species in one. He 

 only mentions Trochus odontis in his list of the South Australian 

 Mollusca.

 It is quite a mysteiw how this species has got confused with 

 the Trochus armillatus Wood figured in the Supplement to the 

 Index Testaceologicus, in 1828, The Trochus Meyeri, Philippi, 

 is quite distinct both as regards colour and sculpture ; the 

 figure given by Eeeve as T armillatus is very bad. The figures 

 given by Philippi, Kiener, and Hombron and Jacquinot of this 

 well-known species are not to be surpassed. Paetel erroneously 

 attributes this species to Dr. Dunker.
