Tlie series agrees in every iletiiil with sjieciiuciis i'rom Ciiinaiui mul S. Paiilo in 

 S. Brazil, the pileiim beinfr olive u;reen like tlie Ijack, and but slif;lit]y mixed with 

 grey. A nunilier of sl< ins from X.E. Peru (Xeberos and ( 'hamicuros, E. Barth>tt 

 t'oll.) have the pilenm grey with very little greenish admixture, and the nnder- 

 snrface distinctly pale yellow. They ought to be called A', s. u/asimilix I'elz., 

 although the types of the latter form have a duller, more greyish greeu back.

The birds from Trinidad are exactly intermediate lietween typical /'. .s. sul- 

 jj/tuiafi'S and P. s. rufpcnnis (Lafr.). The differences of tiie three suljsjiecios may 

 be expressed as follow.s : — 



((/) 1'. .s. m/i'/i'iraOfx (Linn.) 



Uj)per wing- and tail-coverts with scarcely any trace of rnf(jus margins ; (piills 

 narrowly edged with rufous; outer tail-feathers with the extreme base of the inner 

 weiis only rufous.

 aud East Ecuador. 



(b) P. s. trinitatis Hellm. 



Upper wing- and tail-coverts distinctly margined with rufous ; quills more 

 broadly edged with rufous, these edges being separated from the rufous colour of 

 the inner webs by a distinct dusky stripe along the shaft; tail-feathers with broad 

 rufous margins occupying about half the lireadth of the inner web.

SftitnijiIuKjiis riiji2>eniih Lafresnaye, Rcr. Zunl. 1851, p. 471 (Gankas). 



Upper wing- aud tail-coverts almost entirely rufous, only a narrow central 

 streak loeing dusky ; both webs of the quills (except the tips of the primaries and 

 a broad shaft-stripe on the apical half of the secondaries) and inner web of theonter 

 tail-feathers entirely rufous.

The above differences are ipiite constant in a series of .i4 adults.
