Rostrum mediocre avt elongatum, forte, magis minusve conicum, 

 integrum aut versus apicem suhemarginatum, marginibus in- 

 terdum denticulatis : pedes simplices aut gressorii, tetradactyli,

Beak moderate or elongated^ strong, more or less conic, entire or 

 slightly emarginate near the tip, its edges sometimes denti- 

 culated : legs simple or gressorial, four-toed, three placed before, 

 one behind. 



JL HIS tribe, as observed by Mr. Vigors, is distin- 

 guished by the strength and conical form of the beak, 

 and in general by the integrity of its margin : the 

 typical groups are for the most part omnivorous ; the 

 extremes chiefly granivorous : the latter are those 

 which are comprised by Ray among his hard-billed 

 birds. They are thus divided :
