G. B. Sowerby, Senr., at the request uf the late Earl of Tanker- 

 ville's executors i^reparatory to the offer for sale of the unique 

 collection. The description is as follows : — 



" 2260. Ci/prceau7nbilicata. — C. testa oblongo-ovatS, basi acumi- 

 nata, superne subrostrata, umbilicata, dorso ventricoso, pallido^ 

 fusco-maculato; ventre subrotundato, albido; marginibus rotun- 

 datis, albidis, fusco maculatis; apertura, dentibusque subdistan- 

 tibus, pallidissime suljfuscis; long. 3^jy unc, lat. 2^^ unc." 



" Obs. — This singular Cowry, of which we have only seen two 

 specimens, neither of them in good condition, appears not to have 

 been noticed by any author; it is pi'incipally distinguished by a 

 deeply umbilicated spire, the upper part of the aperture being 

 produced and rather reflected, and by its acuminated base : in 

 general form it resembles a pear, and its colour and markings are 

 like those of some varieties of C. Tigris. We are not acquainted 

 with its native country. The other specimen is in our own 

 collection." 



In the Zoological Journal for 1826 (Vol. ii. p. 494) will be 

 found a paper by G. B. Sowerby, Senr., entitled — " Descriptions 

 of two new Species of Cyprtea, principally extracted from a 

 'Catalogue of the Shells in the Collection of the late Earl of 

 Tankerville.' " In this paper the Latin description of C. umbili- 

 cata, and the observations with a slight and unimportant variation 

 in the wording are repeated ; and the following new matter is 

 added : —

 (of the two lips) subrostrated; spire deeply pressed in or umbili- 

 cated, volutions apparent; back ventricose, pale coloured; spotted 

 with brown ; under part rather rounded, whitish ; margins 

 rounded, whitish, with brown spots; the aperture and the teeth, 

 which are rather distant, very pale brownish. Length 3y^^ ;
