12 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 60 



Measurements of male {type). — Wing, 48; tail, 37.5 ; oilmen, 15 ; 

 tarsus, 18.5. 



Remarks. — I have seen no specimens of H. r. frater, which was 

 described from Sarayacu, Ecuador, but so far as the characters of 

 this form are given in descriptions it appears to differ from the pres- 

 ent form, although von Berlepsch and Hartert state that adult speci- 

 mens from the Caura River have the interscapular region black, ap- 

 parently as in the present form (Nov. Zool. 1902, p. 75). Goldman 

 collected only two specimens of this bird, a fine adult male and fe- 

 male.

 E. A. Goldman (collector's number 15630).

Subspecific characters. — Generally similar to typical ftavirostris 

 but smaller with much larger bill ; upper parts with less brownish 

 suffusion, the crown more olive grayish ; back nearly plain olive and 

 outside of wings darker and more olive brown ; tawny ochraceous 

 of under side of neck, breast and sides of body about the same, but

 less numerous on both throat and breast than in typical ftavirostris. 



Measurements of type. — Wing, 64; tail, 26; oilmen, 16.5; tarsus, 

 24. 



Remarks. — This subspecies is based on four specimens, three of 

 which are much alike but the other lacks the dark edges to feathers 

 nf neck and breast as in costaricensis, but the ochraceous of these 

 1 tarts is lighter and yellower, the upper parts greener and less brown- 

 ish olive, and the size smaller with larger bill.
