Cypraea nivea. Gray. Report Proc. Zool. Club. Zool. Jour. i. 

 420. (October, 1824.) 



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



1. Junior. Testa albido-plumbea. 



2. Decorticata. Testa albido-fulva. 



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



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

 witb 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 JL, diameter -g 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 punctisque niveis adspersa, basi 

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

 rufo-flava costato-striatis. 



Cypraea n. 5. Schroeter Einl.j. 134. 



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

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

 Vol. Harpts; are undescribedtffor Cyprcea maculata is C. Arahica, var. of this 

 Monograph; Dolium dentatumjis J), ringens of Swaimon ; and Natica Patula, 

 the shell described under th</t name by Sowerby. As there is another N. 

 patula must be called by Mr. Barneys MS. name of JV. Helicoides.
