Species 18. (Mus. Cuming.) 
PYRULA MELONGENA. Pyrul. testi ovatd, ventricosa, 
superné tumidd, spird parvd, peculiariter demersd, bast 
emarginatd et recurvd ; spire anfractibus transversim 
tenuiliratis, concentricé plicatis, ultimo levigato, nunc 
mutico, nunc tuberculis squamatis prominentibus bi- 
triseriatim armato, apertura perampld, superné cana- 
liculaté ; rubido-fuscd aut cerulescente fasciis angustis 
luteis irregulariter cingulatd, intus alba. 
THE WELL-ARMED PyruLa. Shell ovate, ventricose, 
swollen round the upper part, spire small, peculiarly 
sunk; whorls of the spire transversely finely ridged, 
concentrically plaited, last whorl smooth, sometimes 
armed with two or three rows of prominent squamate 
tubercles, sometimes without ;~aperture very large, 
canaliculated at the upper part; reddish brown or 
blueish, encircled with irregular narrow yellowish 
bands, interior white.

Hab. Kastern Seas. 
This well-known species, like the P. Paradisiaca, is as 
frequently found without tubercles as with. 
Species 19. (Mus. Cuming.) 
Pyruta Bispinosa. Pyrul. testa ovato-fusiformi, trans- 
versim undigue subrugoso-liratd, spire anfractibus con- 
centricé plicato-costatis, suturis squamatis, ultimo su- 
perne angulato, squamarum seriebus duabus ad angulum 
armato, squamarum serie unica prope basin; alba, 
intus aurantio-lutescente. 
THE DOUBLE-SPINED Pyruxa. Shell ovately fusiform, 
transversely rather roughly ridged throughout, whorls 
of the spire concentrically plicately ribbed, sutures 
squamate, last whorl angulated round the upper part, 
armed with two rows of scales at the angle, also 
with a single row of scales near the base; white, 
orange-yellow within.

The leading feature of this species appears to consist in 
the body-whorl being surmounted by a double row of 
scales; a character not observed by Lamarck in his des- 
cription of P. angulata, which it seems most to approxi- 
mate. The specimen here represented from Mr. Cuming’s 
collection, the only one I have seen, does not exhibit the 
brown band represented by Philippi. 
Species 20. (Mus. Cuming.) 
Pyruna patuLta. Pyrul. testé ovata, subpyriformi, ven- 
tricosd, superné tumidd, spird parva, acuta, peculiariter 
demersa ; spire anfractibus concentricé plicato-costatis, 
ultimo levigato, basin versus sulcato, superné concavo- 
depresso, plerumque rotundato, mutico, interdum tuber- 
culorum serie unicd coronato; apertura peramplé, 
superné canaliculatd ; castaneo-fuscd, fasciis lineisque 
luteis cingulatis epidermide crassa fibrosd indutd, aper- 
turd pallidé aurantio-carned. 
THE WIDE-OPEN Pyruxa. Shell ovate, somewhat pyri- 
form, ventricose, swollen round the upper part, spire 
small, acute, peculiarly sunk, whorls of the spire 
concentrically plicately ribbed, the last whorl smooth, 
grooved towards the base, concavely depressed round 
the upper part, generally rounded, and free from 
tubercles, sometimes coronated with a single row; 
aperture very large, canaliculated at the upper part ; 
chesnut brown, encircled with yellow bands and lines, 
covered with a thick fibrous epidermis; aperture 
pale orange flesh-colour.

So closely does this species approximate to the P. me- 
longena, that it might almost be regarded as a variety of 
that species. It appears, however, distinct, and is from 
a very different locality.
