Icon. Barnes. 1. c. t. 9. f. 2. 



1. Junior. Testa albido-plumbea. 



2. Decorticuta. Testa albido-fulva. 



Inhabits China, Barnes. Pacific Ocean. Mus. Nost. 



Shell oblong-ovate, snow white, the margin thickened, rounded, 

 with the upper part of the outer side of the extremity slightly 

 denticulated, the base rather convex, the aperture wide, especially 

 in the anterior part ; the teeth rather large, distant, nearly equal, 

 with the grooves slightly extended towards the margin ; inside 

 brownish white; columella flat, plaited; spire conical, covered. 

 The axis -i^, diameter f of an inch. 



I have had for a considerable time a specimen of this shell, 

 which, from the two holes bored just over the outer lip, has been 

 evidently worn as an ornament by the inhabitants ©f some un- 

 polished nation. It was exhibited at the Zoological Club, under 

 the above quoted name ; but since that time, it has been described 

 by Mr. Barnes, in the Lyceum of Natural History* at New York; 

 and therefore, as his description was first published, I have 

 adopted his name. 



Mr. Mawe has a young and worn specimen of this species ; 

 the former is pale livid white or stone-coloured ; and the latter 

 pale brown with a white base and margin. 



C.ovulata of Lamarck is certainly not the young of this species, 

 as supposed by Mr. Barnes. 



83. Cyprcea guttata. — The Blot ched Cowry. 



Testa ovata, fulva, guttulis punctisquc niveis adspersa, hasi 

 alba, rufo-flavo-venosa, marginibus sub-incrassatis, supra acutis 

 rufo-flav^ costato-striatis.

• I may here remark that of the shells, which Mr. Barnes has so well de- 

 scribed and accurately figured in the above paper, only two, the former and 

 Vol. Harpte ; are undescribedj^for Cyprcea maculata is C. Arahica, var. of this 

 Monof^rapli ; Doliuni denlatum lis />. ringens of Sicainaon ; and Nalica Patiila, 

 the shell describi'd uii'J<?r ihijl imine by SowcMby. As ihtre is another N. 

 patula muHt be called by Mr. BarneH''M MS. name of AT. Ifelicoldes.
