vomerine bones are strongly toothed, and tlie palatine bones large 

 and finely denticulated. There are seventeen teeth in the pre- 

 maxillary bone on each side. They increase in size a little as tbey 

 extend backward. They have a large pulp cavity and a furrowed 

 base to the crown, as iu the preceding types. A second rudimentary 

 row is indicated by a row of five small processes. The vomer is 

 small, and carries seven large teeth in two rows in the anterior

half; and there is a transverse row of small teeth at the posterior 

 border. The palatine bone is unusually large, and shaped as in 

 crocodiles ; it is three times as long as broad ; and the inner borders 

 are in contact throughout their length. Its anterior border is in 

 contact with the vomer and the premaxillary bone, and its outer 

 border is notched to form part of the palatal foramen. The lower 

 jaw appears to have contained about seventeen teeth. 



This short notice may draw attention to the remarkable materials 

 which Professor Fritsch has admirably described and figured, but it 

 can convey no idea of the excellence of the collateral discussions 

 with which he has enriched a work, that grows in merit as it 

 progresses. H. Gr. Sehley.
