Eustachian tubes united into a single ostium pharyngium. No

The few memhers of this suborder have the vertebrae opistho- 

 coelian and deprived of ribs ; the diapophyses of the third and fourth 

 vertebrae are extremely elongate, and those of the sacral are strongly 

 dilated and confluent with the coccyx. 



In Fij)a there are only seven presacral vertebrsB. 



The fronto-parietals are entirely ossified, and there are true ossa 

 nasalia.

 epicoracoid cartilages do not overlap.
