Psilorhinus, Ruffel, Mus. Senck. 1837, 188" Type Pico morio, Wagler. 



Ch. — Color very dull brown above. Bill very stout, compressed, without notch ; higher than broad at the nostrils ; culmen 

 curved from the base. Nostrils rounded ; the anterior extremity rounded off into the bill ; not covered by bristles, but fully 

 exposed. Tail rather longer than the wings, graduated ; the lateral feather three-fourths the longest ; seconditries and tertials 

 nearly as long as the primaries. Legs stout and short, not equal to the head, and little longer than the bill from base. 



This genus embraces jays of large size and very dull plumage. The thick bill, with the much 

 curved culmen', the moderate tail, and the open nostrils, may serve to distinguish it from its 

 allies. The nostril is very large, and its anterior portion is bevelled off to a greater degree than 

 in any genus, except in Oalocitta. This last mentioned genus has the same form of bill and of 

 nostrils, but the head has a long recurved crest ; the tail is twice as long as the wiiigs ; the 

 lateral feather nearly half the middle ; the lateral tarsal plates scutellate for the inferior 

 half, &c. 



In the shape of the bill and the shortness of the primaries, compared with the broad tertials 

 and secondaries, there is much resemblance to Xanthoura. The nostrils are, however, uncovered, 

 the legs much stouter and shorter, being shorter than the head instead of longer ; the tail 

 feathers are broader, &c.
