<i ad. Ditt'ors from a and li by the darker, more slaty j:;rey nppor parts without 

 any trace of greenish on the nimi). The grey colour below is al.so rather darker and 

 more extended, and the flanks are always washed with brownish. Wing, 05 — 08 ;

 in both sexes sulphur-yellow without any white, ('fr. Journ. f. Ornith. 19u5,

The specimens agree with a good series from (Jnmaua and the Orinoco and ( 'aura 

 Rivers in having the under-parts strongly washed with ochraceous buff (Hidgway, 

 NomcDcl. v. fig. 10). The clieeks, ear-coverts and sides of the neck are uniform 

 deep ochraceous (liidgway v. fig. 7), and the back dull smoky brown in decided 

 contrast to the dull rufous brown pileum. Two specimens from Cumamlhave only a 

 slight ochreous buffy wash on the innermost sides of the belly, thereliy appro:iching 

 Jt. m. ((Ihiceidii.s iScl. from I'ritish (Juiana and Surinam ; but the sides nf the head 

 :ire deep ochraceous, as in It. in. trinitatis. 



11. lit. )iicl(ini<rus of East Brazil (S. Paulo to Para) resembles the brightly 

 coloured specimens of R. m. trinitatis on the under parts ; but the ear-coverts are 

 much paler buff, and the back Is warm rufescent brown, scarcely different from the 

 colour of the crown. 



It is extremely doubtful wlu^ther Lesson's name can be accepted for the 

 northern form of R. niflaniaus. Although Trinidad is given as the typical locality, 

 the description does not fit very well, and the terms " corpore infra niveo, lateribns 

 griseis," apply much better to A', m. uthircntris. Perhaps Lesson described a 

 specimen of the latter race with a wrong locality, lietore giving a new name, 

 however, the type of trinitatis should lie examined.
