MITBA.— Plate XXV. 



in the celebrated collection of the late Mrs. Ross, and I 

 dedicate it. to the memory of that lady in consequence of 

 the name given to it by Swainson having been pre-occupied 

 by Martyn, whilst that adopted by Kiener has been used 

 bv its authors to distinguish a shell which is evidently the 

 young or bad state of another species.

The blunt Mitre. Shell ovately cylindrical, rather thick, 

 spire short, blunt; transversely impressly striated; 

 whitish, painted longitudinally with narrow red or ash- 

 coloured lines or stripes, last whorl encircled with a 

 small pale zone round the upper part ; columella four- 

 plaited ; lip strongly sinuated.

Hab. Island of Luzon, Philippines (found under stones at 

 low water) ; Cuming. 



This species, both varieties of which are very character- 

 istically figured by Kiister, differs materially from the Mitra 

 virgata, which has been confounded with it by Mr. Gray in 

 the Zoology of Beechey's Voyage, both in form and sculp- 

 lure, as well as in its style of coloming. The spire is pecu- 

 liarly blunted ; the surface is transversely finely grooved; 

 and the stripes, instead of being white upon a coloured 

 ground, are coloured upon a white ground.

The grub Mitre. Shell ovate, spire short, rather blunt, 

 transversely grooved throughout; brown or light 

 brown, last whorl encircled round the middle with an 

 interrupted row of spots; columella four-plaited; lip 

 contracted in the middle.

May be distinguished from the young of the following 



species by its peculiarly contracted lip. 



Species 201. (Mus. Norris.) 

 Mitra cucumeeina. Mi/r. testa ovatd, ventricosd, uirin- 

 que attenuatd, transversim undique sulcata, /iris inter- 

 mediis convexo-eleoatis ; rubra oel aurantia, anfractu

 lumella quadriplicatd. 



The cucumber-like Mitre. Shell ovate, ventricose, 

 attenuated at both ends, transversely grooved through- 

 out, intermediate ridges convexly raised; red or 

 orange, last whorl encircled round the middle with an 

 interrupted row of white spots. 



Lamarck, Anim. sans vert. (Deshayes' edit.), vol.x. p. 332. 

 Cucumis striatum, Klein. 



Sab. Island of Annaa, Pacific Ocean (found under coral at 

 low water); Cuming. 

 The title of this ancient and well-known species is, I 



believe, derived from an observation made by Pliny, that 



the animal smells like a cucumber.
