MITEA.— Plate XXIII. 



Hah. New Zealand ; Quoy, Deshayes. Island of Burias, 

 Philippines (found imder stones on the reefs at low 

 water); Cuming. 

 The best illustration hitherto published of the Mitra 

 aurantw. is that by M. Deshayes, in the ' Magasin de Zoo- 

 logie,' 1831. Kiener has figured an example of the follow- 

 ing species for it, and Kuster has given an innocent repeti- 

 tion of the error. I think with M. Deshayes that Lamarck's 

 Mitra Peronii is merelj a ' double emploi ' of this species.

Hab. ? 



This species may be easily distinguished from those 

 which it so nearly resembles in general appearance, by its 

 peculiarly flattened ridges.
