Suborder PARASUCHIA. 



No palatal plates developed from the bones of the roof of the mouth, 

 and consequently no secondary posterior nares ; a columella ; anterior 

 nares posterior and divided ; vomers apparent on the palate ; a 

 distinct postfrontal x ; the middle eustachian canal not enclosed in 

 bone ; and the premaxillae (typically) carrying some 21 teeth, and 

 forming a rostrum. Probably a clavicle; coracoid short and 

 rounded, with a very large fontanelle; humerus with an ectepi- 

 condylar groove; pubis entering into acetabulum; probably five 

 digits in each foot 2 . Vertebrae amphicoelous. Dorsal scutes keeled, 

 and arranged in two rows ; ventral scutes (when present) arranged 

 in not more than eight rows, and each scute consisting of a single 

 bone. 



This Suborder connects the Crocodilia very closely with the Sauro- 

 podous Dinosauria. 



Family PHYTOSAURIDiE 3 . 



A descending portion in the basioccipital and basisphenoid ; the 

 premaxillaB interpenetrating the maxillae on the palate ; the orbits 

 completely separated from the large infratemporal fossae ; the pre- 

 orbital vacuities very large; the supratemporal fossae exceedingly 

 small and rudimental 4 .
