TURBONTLLA OBLTQUA. 565 



DififriJ)ufion. — Not recorded living. 

 Fossil: St. Erth. 



Remarlis. — The shell figured under the present name is from the St. Krth 

 Collection in flie British ^luseum, where it has lieen identified with Tarho plicahili(s 

 of Brocchi, but though belonging to a similar group it is not the same, nor is it the 

 Chemnifzia jiUcatuhi of Wood. The nearest thing I can find to it is one of the 

 fossils from Monte Mario, described by Sign. Cerulli-Irelli as Turhoidlla pallida, 

 Phil.\ but our specimen shows no trace of the spiral sculpture of Philippi's species. 

 It is an interesting form, differing from anything else I know from St. Erth, and 

 deserves notice. I figure it, therefore, as new, suggesting it should be called 

 T. expallida.

Eemarks. — The specimen here figured is from St. Erth and belongs to the 

 British Museum. It was originally but not sufficiently described or figured 

 by Mr. Bell in 1893 under the name of G. Warringtoni. Submitting a photograph 

 of it to M. Dautzenberg, he remarks that it is probably identical with the 

 T. ohliqua of Degrange-Touzin (1895), subsequently refigured and described by 

 MM. Cossmann and Peyrot in 1917.

^ As Mr. Bell did not adequately describe C. Warringtoni, the name afterwards adopted by M. 

 Degrange has therefore the pi-iority.
