Postfrontal 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. 
developed crest or tuvercle’projecting below the condyle ( 
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 sma!l, with round pupil; scales smooth, 
without pits ........ sypery Nise 6. Polyodontophis, 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, without pits ...... 7. Dromicodryas, p. 189, 
I. Hypapophyses present throughout the vertebral column, repre- | 
sented on the posterior dorsal vertebre by a more or less” 
* 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 is the premaxillary in, all Snakes, except some of the 
Boida and Ilysitde and Xenopeltis,
