BiE slender to moderately stout, longer than head, the culmen as 

 narrowly elliptical or slitlike, on line with axis of maxilla^ much 

 posterior to middle of maxilla, its posterior end separated from 

 laterof rontal antia by a space about equal to basal height of maxilla ; 

 laterofrontal angle at base of upper edge of nasal fossa, thence 

 long as or longer than tarsus, slightly elevated and widened basally, 

 slightly depressed and more constricted medially, slightly (but usually 

 decidedly) decurved distally, rounded (in transverse section)

 more, sometimes less), nearly straight (except at tip, where more or 

 less convex), not prominent basally, the mandibular rami without 

 distinct lateral groove; nasal fossa extending for much more than 

 half (sometimes for two-thirds) the length of maxilla (measured 

 from laterofrontal antia), well-defined throughout; nostril very 

 receding in a straight or gently curved line to the rictus ; malar antia
