is small and starved. The other species are such as might be expected 

 to-day in the latitude of the northern Mediterranean and at a depth probably 

 not exceeding 50 fathoms. 



Having made an exhaustive study of the Eocene clays of Selsey Bill, 

 and of the C6te des Basques of Biarritz, the results of which have been 

 published elsewhere, 1 we think it advisable, or, at any rate, of interest to 

 compare these gatherings with the small sample under discussion. We have 

 therefore appended the letter 6". to species found at Selsey, and the letter B. 

 to species found at Biarritz. It will be observed that of the 51 species 

 recorded below, 33 have been recorded from Selsey, 35 from Biarritz and 25 

 from both localities. The complete absence of Nwnmulites> and, excepting in 

 a few isolated " casts ", of Glauconite, is a very unexpected feature in what 

 purports to be an Eocene clay. 



It is possible that a few of the specimens are derived from older strata, 

 notably the cast of Discorbina globularis (d'Orb.) and another cast of an 

 unidentified species of Vaginulina. Neither of these specimens have the 

 characteristic appearance of the other fossils. Among the Nonioninae, the 

 limbate individuals of N. boueana, d'Orb. are stained and eroded, whereas 

 the others preserve their hyaline texture. On the other hand, the Miliolids 

 are, in general, in a state of preservation quite remarkable for specimens of 

 this genus.
