MlTRA.— Plate XXIX. 



Reeve, Pro. Zool. Soc, 1845. 



Hub. Island of Burias, Philippines (found among coral sand 



and shells at the depth of four fathoms) ; Cuming. 



This species is well characterised by the very elegant 



style of its sculpture, and by the sharp red line or lines 



with which it is encircled.

The graceful Mitre. Shell somewhat fusiform, con-

 deep; transversely impressly striated, intermediate 

 ridges graimlous, ornamented longitudinally with nar-

Hah. ? 



A species of peculiar interest, whether in regard to form, 

 colour, or sculpture.

 The changeable Mitre. Shell abbreviately fusiform, 



spire turreted, sometimes elevated, sometimes rather 

 short, sutures somewhat deep ; whorls depressed at 

 the upper part, longitudinally concentrically ribbed, 

 ribs narrow, latticed with fine transverse ridges ; 

 whitish, banded with olive-green ; apex brown ; colu- 

 mella four-plaited. 



Reeve, Pro. Zool. Soc., 1845. 



Hah. Island of Ticao, Philippines (found under stones, 

 at low water, and at the depth of about ten fathoms) ; 

 Cuming. 

 An extremely variable species both in form and colour, 



the chief variations of which are represented by comparison 



in the accompanying figures. 



Species 236. (Mus. Cuming.)

The military Mitre. Shell somewhat fusiform, con- 

 tracted at the base, spire acuminated, sutures rather 

 deep; longitudinally ribbed, ribs somewhat obtuse, 

 interstices transversely impressly lineated ; whorls yel- 

 low at the upper part, last whorl encircled with a 

 broad crimson red zone; columella four-plaited, urn- 

 bilicated. 



Reeve, Pro. Zool. Soc, 1845. 



Hob. Island of Ticao, Plulippines (found on the sands) ; 

 Cuming. 

 This species may be readily distinguished by the rich 



broad crimson-red band which encircles the last whorl. 



The whole of the Mitres figured in this plate are peculiarly 



characteristic, and distinct from any of the species that have 



come under my observation.
