FAJUMIA SCHWEINFUETHI. 31; 



Class PISCES. 



Eemains of Fishes are fairly common in the Qasr-el-Sagha beds, but are rare 

 in the Fluvio-marine (Upper Eocene) series above. The commonest forms from 

 the lower horizon are large Siluroids and Sawfishes ; these have been described 

 by Dr. E. Stromer*, so that here it will only be necessary to give a brief account 

 and list of the specimens in London and Cairo. 



Subclass TELEOSTOMI. 



Order ACTINOPTER YGI I. 



Suborder OSTABIOPHTSI. 



Family SILURID^. 



Genus FAJUMIA, Stromer. 

 [Neues Jahrb. 1904, vol. i. (Abhandlungen) p. 3.] 



This genus was established by Stromer for the reception of a species of Siluroid of 

 which remains are very common in the Qasr-el-Sagha beds. It appears to be allied to 

 Arius, one of the chief differences being that the complex vertebra is not fused with 

 the skull, there being no subvertebral process at the junction.
