PYRULA. 
Prate IV. 
Species 14. (Mus. Cuming.) 
Pyruta BuLBosa. Pyrul. testé pyriformi, ventricosissind, 
spire suturis impressis, anfractibus transversim striatis, 
 bifariam vel trifariam squamato-tuberculatis ; columella 
ampliter umbilicaté ; canali brevissimo; aperture 
Sauce radiatim sulcaté ; extus rufescente-fuscd, intus 
carned. 
THE BULBOUS Pyruza. Shell pyriform extremely ven- 
tricose, sutures of the spire impressed, whorls trans- 
versely striated, encircled with two or three rows of 
squamate tubercles; columella very largely umbili- 
cated; canal very short; interior of the aperture ra- 
diately grooved; exterior reddish-brown, interior 
flesh colour.

Pyrula rapa, Lamarck. 
Murex rapiformis, var. a. Born. 
Hab. Eastern Seas. 
The Pyrula papyracea Lamarck, and not the species 
under consideration, is Murex rapa of Linneus; hence 
the necessity for an alteration of names. I do not how- 
ever agree with the learned editor of the ‘Anim. sans vert.’ 
in adopting Born’s specific title, xapiformis, whilst there is 
already a P. rapa. 
Species 15. (Fig @ and ¢ Mus. Belcher, Fig 6 Mus. Cuming.) 
PyR ULA BEZOAR. Pyrul. testd abbreviato-pyriformi, ven- 
tricosissimd, crassiusculd, transversim striata, trifariam 
vel quadrifariam squamato-tuberculatd, anfractibus su- 
perné angulatis, supra angulum interdum concentrice 
Jimbriato-plicatis ; columelldé subumbilicaté ; aperture 
fauce radiatim sulcaté; albido-fuscescente, cingulis 
angustis nigris plus minusve articulatd, intus rufo- 
aurantia. 
THE BEZOAR Pyrvta. Shell abbreviately pyriform, very 
ventricose, rather thick, transversely striated, encir- 
cled with three or four rows of squamate tubercles ; 
whorls angulated round the upper part, sometimes 
concentrically fimbriately plicated above the angle ; 
columella moderately umbilicated ; aperture radiately 
grooved; whitish brown, more or less articulated 
with narrow black zones, interior reddish orange.

Buccinum bezoar, Linneus. 
Purpura bezoar, Kiener. 
Murex rapiformis, var. 8 Born. 
Hab. Eastern Seas. 
To illustrate this extremely variable species in an ade- 
quate manner, I have selected three specimens exhibiting 
its most distinct phases of growth. In Fig 15 3. which is 
that of most common occurrence, the upper part of the 
whorl is crowded with fimbriated plaits ; Fig 15 a. is chiefly 
characteristic of the narrow articulated zones of dark 
painting, of which there are indications more or less in all 
specimens ; and Fig 15 c. represents a magnificent example 
of finely expanded growth richly coloured in the interior,
