Syn. Cypraea umbilicata, Sowerby, in Tankerville Catalogue, 

 appendix p. xxx. No. 2260. cum Icon. 



This singular Cowry, of which I have only seen two specimens, 

 one in the Tankerville Collection and one in my own, neither of 

 them in good condition, appears not to have been noticed by any 

 author : it is principally distinguished by a deeply umbilicated 

 spire ; by the upper part of the aperture being produced and 

 rather reflected and by its acuminated lower extremity : in gene- 

 ral form it resembles a pear and its colour and markings are like 

 those of some specimens of C. Tigris, of which, however, it 

 cannot be considered a variety and from which it differs not only 

 in the marks above mentioned, but also in the form and position 

 of the teeth. I do not know its country.
