dinarily thin skin, it is worth mentioning that this specimen's skin 

 was no more delicate than that of any other bird of equal size. 



An example of July 22, sexed as a male, is like the adult female 

 but has the black-barred buffy secondaries and pointed rectrices of 

 immaturity. A male of August 28 has almost wholly assumed the 

 red head an dbreast of the adult but shows its you in wings and 

 tail. A male of October 21 retains only one of the immature sec- 

 ondaries but has some brown feathers among the crimson of head 

 and breast and the rectrices pointed. Males of December 15 and 

 February 21 have lost all marks of the juvenal dress except the 

 acuminate tail feathers. 



An adult female, collected on May 10, is acquiring one new central 

 rectrix, but the loss of the old feather may have been due to accident. 

 Adults that are clearly in molt were taken on August 23 and Septem- 

 ber 1 and 5. 



De Schauensee's specimens had the irides reddish brown ; the orbital 

 skin violet; the bill violet, with the entire culmen and the edges of 

 the commissure on the basal half black ; the rictus purplish red ; 

 the feet and toes fleshy pink; the soles yellow. Gyldenstolpe states 

 that his females had the irides plain brown, while the males had them 

 pale brown, reddish brown, or (in one case) bright red, and that both 

 sexes had the bill black with the base blue, the feet and toes pale gray. 



My nestling male had the irides gray with a narrow, dark outer 

 ring ; the orbital skin flesh color ; the bill black, white at the tip, fleshy 

 at the base ; the rictus and interior of the mouth fleshy ; the feet and 

 toes flesh color; the claws horn-brown, tipped fleshy. 



The adult male has the head, neck, throat, and breast deep crim- 

 son; an indistinct, narrow white crescent across the lower breast; 

 the remaining underparts brighter and lighter crimson ; the primaries 

 black; the secondaries and upper wing coverts finely vermiculated 

 black and white; the central pair of tail feathers chestnut, narrowly 

 tipped with black ; the next two pairs black, with some chestnut ; the 

 others black with white outer webs and broad white tips ; the remain- 

 ing upperparts golden-brown, more ferruginous on the rump and up- 

 per tail coverts. The adult female has the head, neck, throat, and 

 breast colored like the back and the rest of the plumage similar to 

 that of the male. Adults of either sex have the rectrices square-tipped 

 and slightly flaring near the end.
