rior vertebrae, and pectoral arch of this fish is given for comparison 

 (Plate XXII. fig. 4). 



Notwithstanding the general resemblance, it will be seen that 

 there are several important differences of detail. In the recent fish 

 the sutures are persistent, the head is broader and flatter, and the 

 orbit and frontal fontanelle much smaller. The posltemporal and 

 pectoral arch are also relatively smaller, and the latter tapers below ; 

 while the infraclavicle appears to be much less developed. 



Konig's name of Bucklandium diluvii may thus be retained for the 

 fossil now described, and, upon present evidence, this Eocene fish 

 may be most closely associated with an African type. It ought to be 

 remembered, however, that most of the living allies of Juchenoglanis 

 are denizens of South America ; and in this connection it is interesting 

 to note a fact kindly communicated by Mr. Etheridge, that the 

 moUuscan fauna of the London Clay has about as many living 

 representatives upon the south-east coast of North America as upon 

 the western coast of Africa.
