riorly and considerably produced behind ; inner or columellar lip also 

 produced behind and separated from the outer lip by a narrow channel 

 or canal ; characters of the interior of the aperture unknown, though it 

 clearly extended the whole length, and is narrow and linear behind. 



" Surface smooth. 



" Dimensions of the specimen described (which has been kindly pre- 

 sented by its discoverer to the Museum of the Geological Survey) : 

 length, twenty millimetres ; greatest breath, twelve millimetres.

"Most of the aperture of this interesting little fossil is filled with the 

 tough and tenacious matrix, so that it is impossible to ascertain whether 

 there are or are not any crenulations on the inner surface of the outer 

 lip, or any denticulations or plications on the columellar side. The 

 external characters of the specimen, however, would seen to show that it 

 is a small smooth Cyprcea, very closely allied to the C. Cunlijfei of 

 Forbes, * from the Arrialoor group of the Trinchinopoly district of 

 Southern India, and it may prove to be only a variety of that species. 

 The Cyproea Bayerquei and C. Mathewsoni, described in the first and 

 second volumes of the Pala3ontology of California, as from the Tejon 

 group of that state, are now generally regarded as Eocene fossils."

Several much finer specimens of this singular species than the one 

 obtained by Mr. Richardson in 1871, were collected at Hornby Island 

 by Mr. Harvey, in 1894, 1895 and 1897, and most of these are now in 

 the Museum of the Survey.
