It is, therefore, recommended that T. tricingulata be written off as 

 unrecognisable. 



ZlZIPHINUS FRAGUM Philippi. 



The original of Reeve's Conch. Icon. Ziziphinus, fig. 49, intended 

 for Z. fragum Philippi, is marked in the British Museum as not 

 that species. This specimen is perhaps an unnamed Australian 

 Calliostoma, and resembles C. scob hiatus Adams, from Bombay. 



Ziziphinus monile Reeve. 



Ziziphinus monile Reeve, Conch. Icon., xiv., 1863, PL vi., sp.39. 



In the British Museum is one specimen probably the type, but 

 not so marked, labelled, "monile, Reeve, Port Curtis," and under- 

 neath the tablet "Compare with millegranus." On making the com- 

 parison suggested, and allowing that the superficial sculpture has 

 been obliterated with acid, I find that Reeve's shell answers in size, 

 shape, colour, and sculpture to Trochus millegranus Philippi, from 

 Sweden. What I had identified from Mast Head Island as C. 

 monile* proves to be C. polychroma A. Adams. The conclusion is 

 that Z. monile Reeve should be rejected from the Australian record.

 (1853), p. 166. 



In the above reference Adams reports the species from "Rains 

 (sic!) Island, luce." The species is South African according to 

 the British Museum collection, and the Queensland locality neces- 

 sarily false.
