Hab. ? 



There is a peculiarity in the colour and marking of 

 this species by which it may be always distinguished 

 from the Mitra cardinalis, with which it is closely allied 

 in other respects.

 solidd ; anfractibus fortiter coronatis, prioribus sub-

 There are sometimes, but very rarely, two rows of 



holes round the middle of the whorls throughout.

 Mitra ambigua, var., Kiener. 



Hab. Islands of Annaa and Taheite, Pacific Ocean (found 

 on the reefs in shallow water) ; Cuming. 



For another figure of this species, in which the scat- 

 tered white specks are somewhat obscurely represented, 

 see Plate VI. fig. 24 b. It is quite distinct from the 

 Mitra ambigua.
