 tinged with purple.

 the depth often fathoms) ; Cuming. 

 The bands in this beautiful species have a peculiar 



castellated appearance, which is very characteristic.

The cancellated Mitre. Shell fusiform, spire some- 

 what acuminated, sutures crenulated ; whorls trans- 

 versely impressly lineated, cancellated with raised 

 longitudinal stria; and a few irregular obtuse 

 ridges ; yellowish, encircled with three rather in-

 the same colour running between them, longitudinal

Hab. ? 



This shell is at present unique in the collection of 

 Mr. Cuming, and a very interesting well-defined species 

 it is. M. Kiener's assumption that it is a variety of the 

 Mitra buccinata (properly glabra), Sp. 43, is prepos- 

 terous.

The chaste Mitre. Shell narrow, elongated, spire 

 sharp; whorls smooth, punctured round the upper 

 part, ivory-white, encircled with a very broad 

 band of chestnut-brown epidermis; columella four- 

 plaited.

 I am surprised that both Chemnitz and Lamarck, as 



well as Kiener, should have described the Mitra casta as 



being a brown shell banded with white, after the very 



accurate account given of it by our countryman Martyn. 



The brown colour is in fact quite superficial, and exists 



only in the epidermis spirally winding round the shell, 



which is a pure ivory-white. 



Species 41. (Mus. Norris.)

The snow-white Mitre. Shell fusiform, encircled 

 throughout with very finely punctured impressed 

 striae ; white, encircled with obsolete rather distant 

 orange-brown lines, ornamented with a very few- 

 scattered spots of the same colour next the sutures ; 

 columella six-plaited.

Huh. Island of Annaa, Pacific Ocean (found on the reefs 

 at low water) ; Cuming. 



This shell does not appear to be naturally white, but 

 rather worn ; the faint orange-brown colouring above 

 described is, I think, an indication of more important 

 painting.
