98 DR. RICHARDSON'S DESCRIPTION OF AUSTRALIAN FISH. 



length of the upper one. The jaws are more nearly of a length than in some other spe- 

 cies. The teeth differ somewhat from those of P. insidiator, as described in the ' Histoire 

 des Poissous,' particularly on the palate bones, where, instead of a single row, there is a 

 villiform stripe, broadest in the middle, and nearly as wide as the band on the limb of 

 the intermaxillary. There is a narrower stripe on the fore part of the vomer. Of the 

 twenty-seven vertebrie eleven carry ribs.
