Po.stfroutal bone not produced over the supraorbital region. 

 Maxillary and dentary bones armed with solid teeth along their 

 whole length ; palatines and pterygoids usually toothed *. Scales 

 usually imbricate. 



Cosmopolitan ; but very scantily represented in Australia. 



Synopsis of the Genera. 



I. Hypapophyses present throughout the vertebral column, repre- 

 sented on the posterior dorsal vertebrae hy a more or less 

 developed crest or tubercle projecting below the condyle (see 

 fig. 12, A, p. 171). 



A. Dentary bone attached loosely to the apex of the articular 



and freely movable on it (see fig. 14, p. 181) ; teeth very 

 numerous and closely set, equal, 30 to 50 in each maxillary. 



Eye moderate or rather small, with round pupil ; scales smooth, 

 without pits 0. felyedoatephis, p. 181. 



B. Dentary bone not or but slightly movable on the articular. 



1. Maxillary teeth equal, 20 to 30 ; anterior mandibular teeth 

 enlarged ; eye moderate or large, with round pupil. 



Scales smooth, vtdthout pits 7. Dromicodryas, p. 189. 



* Unless the contrary be stated in the generic diagnoses, the palatine and 

 pterygoid bones are understood to be armed with teeth ; the vomers are con- 

 stantly toothless, and so i.s the premaxiliary in all Snakes, except some of the 

 Boidcp and Ili/siidiB and Xeiwpelfis.
