Ileterorhynchis Humei. 41 S 



eJg'ed with olive green ; the chin^ and throat and the sides of the 

 breast are a sort of brick-dust red^ and all the feathers of the 

 breast are more or less tinged towards the tips with this color. 

 (There is no mistake about this; we dissected the birds, and 

 though some of the females have a little less red than others, 

 they all exhibit it conspicuously.) The rest of the lower surface 

 varies somewhat in shade in different specimens, but i\\ all is a 

 yellower, and paler olive green than the upper surface.

Heterorhynchus, Netv Genus. 



Characters. — Bill in form like that of Stacliyrls, but longer and 

 deeper, and the section of the lower mandible very square ; nostrils 

 long, and horizontally situated in a shallow short groove ; they 

 are sheltered by a sort of tect, or small segmental projecting 

 shelf; wings short and much rounded ; the first or small quill 

 is unusually large and reaching nearly two-thirds the length 

 of the wing ; 2nd, "40 inch longer than 1st ; 3rd, '28 inch 

 beyond 2nd ; 4th, "2 longer than 3rd ; 5th, '1 inch longer thau 

 4th ; 6th, '05 inch longer than 5th ; 7th, -03 inch longer than 6th, 

 and the longest in the wing ; 8th, slightly longer than 6th ; 

 and 9th, about equal to 5th ; from this they gradually decrease 

 in the usual manner of very rounded wings. These proportions 

 appertain to a wing 2*7 inches long. The legs, feet, and claws 

 are stout and strong, and similar to those of a Garrulax or 

 Troclialopteron ; tail much graduated, broad, and soft, of 

 moderate length or rather short for the bird ; plumage, soft and 

 laxj and in character like that of Garrulax or Trockalojiteron.

Description. — Color generally a pure black, spotted or streaked 

 on the head and upper back with rufous brown ; the feathers on 

 the back, the wing coverts, and the outer webs of the quills are 

 finely barred with the same color ; the tail is also finely barred with 

 rufous brown : the spots or small streaks on the forehead are 

 nearly pure white, so are some down the side of the neck, reach- 

 ing to the bend of the wing ; most of the feathers of the upper 

 surface are light shafted^ so are those of the whole lower surface :
