as far as behind the fourth maxillary tooth, or further than in the recent forms with 
which it has been compared. 
Tlie anterior portion of a large mandible, probably belonging to this species, has 
been found. As might have been expected from the longer premaxillary region, the 
symphysis is more elongated than in C. porosus, C. 2 )C(liidosns, and C. niloticus, and 
extends backwards to the level of the hinder border of the alveolus of the sixth 
tooth ; the splenial takes no share in its composition. The upper surface of the 
symphysis is marked by a ridge along the line of junction of the two rami, while 
its ventral surface is somewhat flattened. The anterior tooth is large ; it is 
followed by three smaller ones, then comes the greatly enlarged fourth tooth, followed 
by five smaller sockets. The two following teeth (10 and 11) are again very 
large.

Crocodilus sp. 
From the Qasr-el-Sagha beds (Middle Eocene) some very fragmentary remains 
of a broad-snouted Crocodile have been obtained, but the material is insullicicnt to 
determine whether or not this is a new species. Possibly some of the vertebrte and 
other bones enumerated under Tomistoma africanum should be placed here. 
The best-preserved fragment is the anterior portion of the left ramus of a mandible. 
The symphysis extends to the level of the hinder border of the fourth tooth. Tlu' 
first tooth is rather large, the second and third are small, while the fourth is greatly 
enlarged and raised on a prominence of the alveolar border. Pehind it are four 
small teeth, then two large ones ; beyond this point the bone is broken away.
