EXOTIC CONCHOLOGY, 



is crowned with a series of nine or ten muricated tubercles, becoming obsolete 

 towards the thin and acute outer lip which is detached from the spire, (whose apex 

 is smooth and unarmed,) by a deep sinus. The mouth is elongated and tolerably 

 large, the pillar rounded, oblique, and furnished with four large and equidistant 

 plaits. The colour of this excessively rare species, which appears to have been 

 unknown even to the indefatigable Lamarc, is pale pinkish fulvous, and graceful lines 

 of a rich brown traverse it lengthways in angular and distant waves. The length 

 is four inches and a half, the breadth two inches and a quarter. From whence it 

 came is unknown to me, but a fine specimen is preserved in the valuable collection 

 of Mr. Lincoln. 



V. CHRYSOSTOMA. GOLDEN-MOUTHED VOLUTE. 



Plate XLV. 

 Testa turbinata, tuberculis brevibus fornicatis acutis coronata : alba lineis angulato-flexu- 



osis, maculisque angularibus continuis rufo-fuscis longitudinaliter fasciata : spira 



muricata: labro intus aureo : columella 4 plicata.

Shell turbinate, oval, white, with angularly flexuous reticulated lines, and 

 rich red brown wavy and angular masses longitudinally arranged upon the body- 

 whorl, whose summit is crowned with short, vaulted and acute tubercles, which 

 extend up the first few succeeding whorls of the spire ; the apex however is smooth 

 and mammillary ; the pillar is pale yellow, and furnished with four strong but 

 not oblique plaits, and the aperture is brilliant gold colour. At first sight this 

 species might be taken for a variety of Vespertilio, from which it may be distin- 

 guished by difiference of colouring and marking, the smallness and nearness of its 

 vaulted spines, the comparative shortness of its body-whorl, and the lovely hue of 

 the aperture. Two inches.
