20 EXOTIC CONCHOLOGY. 



plaits, of which the three middle are the largest. The angulated markings on the 

 back are orange brown, and not disposed in bands. I am unacquainted with its 

 locality, which may probably be the Pacific ocean.

This species, less remarkable for it beauty than its rarity and singularity, is 

 smooth, solid and ovate-oblong, very ventricose and turgid at the upper part of the 

 body-whorl, but with a spire so short, and a base so attenuated, as to become almost 

 pear-shaped. The outer lip is arcuated, the mouth white and the pillar furnished 

 with four strong and slightly oblique plaits. The colour is yellowish white, adorned 

 with flexuous and narrow streaks of a rust colour which are longitudinal and inter- 

 rupted, and sometimes marked with pale ashy- violet zones. Length two inches and 

 a half. Locality ? 



Obs. In the figures we have quoted the shell appears not lineated but spotted. 

 The series of specimens in the British Museum, however, establishes their identity. 



C. GRACILIS. SLENDER CYMBIOLA. 



Plate XLIL 



Testa fusiformi, leevi, pallide fulva, liueis spadiceis, angulato-flexuosis tantum non reti- 

 culata ; ultimo anfructu mutico, spira tuberculato-plicati : columella quadri- 

 pUcata. 



This graceful shell is but a variety of Pacifica and not a distinct species. It 

 is fusiform, smooth with the spire roughened by blunt tubercular plaits, from which 

 the body-whorl is free. The colour is that of pale burnt Sienna (a hue peculiarly 

 common to the Volutidse) prettily variegated by numerous longitudinally waved 

 chesnut lines, so close as almost to form a network over the entire surface : the outer 

 lip is acute, the aperture whiteish and slightly empurpled, and the pillar furnished
