curving slightly outward and noticeably downward. In color 

 they are rufous-buff barred with dark brown. The delayed 7th 

 to 10th primaries do not finish their growth until the body-moult 

 into adult plumage is well on toward completion. 



The post-juvenile moult into the first winter plumage brings 

 the members of this genus into fully adult dress. 



ITHAGINIS SINENSIS. 



Natal Down. — When compared with the corresponding 

 chick of Ithaginis cruentus many differences are noticeable. The 

 head and neck with the cold gray, almost white, and black mark- 

 ings are similar, but the down of the entire body, above and 

 below, is very much colder and grayer in sinensis. Instead of 

 warm rufous-buff above, there is only a trace of this on the 

 mantle down. A central back stripe is grizzled grayish-brown 

 and two lateral stripes are pale creamy buff. The breast has 

 a tinge of buff, but this hue is scarcely noticeable on the rest 

 of the ventral surface, the chin, throat and belly being white. 



Juvenile Plumage. — This too is unlike the corresponding 

 stage in cruentus. The forehead and crown are not buff but a 

 grayish brown, banded with black and buff on the occiput and 

 nape. The color of the upper surface is distinctly grayer, the 

 terminal pale buff spots thus standing out much more clearly. 

 The black bars on the wing-coverts are also more distinct. The 

 ventral pattern is wholly unlike that of cruentus. There is no 

 trace of the pale buff shaft-stripe, but the feathers are a brown- 

 ish buff, indistinctly marked with darker and tipped as on the 

 dorsal plumage with a pale buff shaft-spot. This is especially 

 distinct on the breast and upper belly, the feathers posteriorly 

 becoming very loosely vaned, all distinct characters being lost. 



Genus Tragopan. 



Unlike Blood Partridges, the Tragopans do not acquire the 

 adult plumage until the second autumn. Many wholly unsup- 

 ported statements have been made concerning the early plu- 

 mages and moults of these birds, the general impression being 

 that the change from the juvenile to the first year plumage, and 

 from this to the adult dress is a gradual process; if not by a
