There is absolutely no difference between the si)ecimens from Ecuailor and 

 N.E. I'ern and those from Bogotd, tliongh tlie latter have been referred by 

 Dr. Sclater to //. IciiooHtUjmd. In two exaiuj)les (Nos. :? and T of the above list) 

 tlie white ajiical s]iots on the npjier wing-coverts are (juite as larjje as in fi. x. h'liro- 

 sti<imfi, while in all the otlicr males tjiere arc only very small dots, jnst as in 

 6'. «. sc/a'staccd. 



Nos. 4, 5, and lo arc immatnre males, showinj;- some remains of the jnvenile 

 ]ilnma;;e. The flanks and nnder tail-coverts are still rnfons brown, and most of the 

 ijnills rnfcscent brown (instead of black with slaty margins), eto. 



? ad. Easily distingnished from that of S. .9. scJiistacea in having the lower 

 mandible whitish and the top of the licnd slate-grey, sharply defineil against the 

 rnfons brown back : from that of the following snbsjiecies by its slightly shorter 

 beak and rather shorter tail.

I'esidcs these specimens, I have examined the series in the British IMusenui. 

 including the typo of 7/. simjth'.r from Surinam. 



c? ad. Agrees with .S'. .9. suhpliimhca in having the lower mandible whitish, 

 but differs in the much paler colonr of the lower parts, which are light grey, 

 passing into whitish on the chin .and middle of X\w. abdomen. The blackish njjper 

 wing-coverts have always large ronnded white apical spots, like the two specimens 

 of & .?. snbpliimheit mentioned above (Nos. 3 and 7 of the list of 5. x. .vtbjditmbcti),
