496 Mr. G. B. Sowerby on two new species of Ci/prcea. 



Syn. Cypraea melanostomaj Leathes, M. S. ined. Sowerby in 



Tankerville Catalogue, appendix p. xxxi. 

 Icon. t. xviii. f. 3 et 4. 



This Gowry, which as I have been informed, is found in the 

 Red Sea, does not appear to be uncommon ; we do not however 

 find it described either by Dillwyn, Lamarck, or Gray. It has 

 been mistaken for C. Vitellus, to which it approaches nearly in 

 general appearance. It has, nevertheless, been long distinguished 

 from that species by the late George Humphrey and by Mrs. Mawe : 

 it may be known by its want of the arenaceous transverse lines 

 so characteristic of C. Vitellus; the teeth on the inner lip are 

 smaller than in that species and their interstices are of a dark 

 violaceous brown colour : the teeth of the outer lip are larger 

 than those of the inner : and the whole margin of the shell is 

 whitish. In an incomplete state it is destitute of the pearly white 

 specks on the back. 



Cypr^a guttata, t. xviii. f. 1 et 2. 



Two views of the only specimen of this shell known in this 

 country are given in the 18th plate of the present volume of the 

 Zoological Journal; the species being already described in the 

 course of Mr. Gray's paper on Ci/prwidce, (Zool. Journ. Vol. I. 

 p. 511.) no further description is necessary. The figure will, 

 moreover, give a very correct idea of this beautiful and valuable 

 shell. I am indebted to Mr. Broderip for permission to draw it, 

 and to Mr. Crouch for the execution of the whole plate, which 

 he has obligingly presented to the Conductors.
