their length. Interorbital space flat, its edges laterally ridged and 

 overhanging, but not forming distinct postorbital processes. Bullae 

 large and transparent, but their anterior not so much swollen as to 

 project lower (in the natural position) than the posterior part. 



Teeth rather variable in size. Upper canine short, flattened 

 laterally. P.' about equidistant from the canine and p." ; p.* trian- 

 gular in section, narrower in front than behind, its point but little 

 higher than that of p.' Lower i.' more rounded in section and less 

 spatulate than usual ; intermediate teeth comparatively well deve- 

 loped, closely fitting against one another ; p.S although quite in 

 series with the small teeth in front of it, yet showing a tendency 

 towards the usual elongated triangular shape.

* The species not being really indigenous to Norfolk Island, this name is 

 ■ incorrect, and therefore untenable. It is also not by any means certain that 

 Phillip's description, and therefore Kerr's name, do not really refer to P. brevi-
