TORTIAllY VERTEBRATA OF THE FATtTM. 
ns far as behind the fourth maxillary tooth, or further than iu the recent forms with 
wliich it has been compared. 
'J’he anterior portion of a large mandible, probably belonging to this species, has 
been found. As migbt have been expected from tbe longer premaxillary region, the 
sym])liysis is more elongated than in C. porosus, C. ‘pnlndosus, and C. niloficus, and 
extends backwards to the level of the hinder border of tbe 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 flve smaller sockets. Tbe two following teeth (10 and 11) are again very 
large.

Crocodiliis sjt. 
From the Qasr-el-Sagha beds (Middle Eocene) some very fragmentary remains 
of a broad-snouted Crocodile have been obtained, btit the material is insuflicient to 
tletermine whether or not this is a new species. Possibly some of the vertebrai and 
other bones enumerated under Tomistoma (ifricanitm should be placed here. 
'fhe best-])reserved fragment is the anterior ))ortion of the left ramns of a mandible, 
'riie symphysis extends t(' the level of the hinder border of the fourtb tooth, fl'he 
first tooth is rather largo, the second and third are small, while the fourth is gi'eatly 
enlarged and raised on a prominence of the alveolar border. Pebind it arc foui- 
small teeth, then two large ones ; beyond this ])oint the bone is broken away.
