 shorter tail. 



A yonng bird in flnlly plnmage. from the upper Rio Negro, belongs most 

 (tertainly also to cincrareu, altliongh it is darker, more smoky brown, on the back, 

 and more ochreons on the throat. But it is still less brightly coloured than yonng 

 birds of .^V. r. ruhecula, and shows the long bill as well as the nniform blaekisli 

 grey sides of the head characteristic of y. >: rincracea. 



The range of the two races is, as far as onr present knowledge goes, the 

 following : —

This species, of which Mr. Hoffmanns obtained a single adult female on his 

 first expedition to the Rio Bladeira in lUiKJ, is somewhat like A', r. ridjerula, 

 having the ni>per [larfs warm brown, bnt may bo distinguislied by its much smaller 

 size (wing 02 ; tail 53i mm.) ; deep ochraeeons bnff (instead of white or ]iale 

 bnfiy) frontal baud, lores, and chin ; duller, more greyish fulvous, throat and 

 forcneck, wiiich, however, are much dcejier in tint than in A', r. rinrracea, etc. 

 Like the latter race, it lacks tlie whitish ])atcli below the eye, and lias the flunks 



• Sclater (Muiuyi: Jacamars anil I'liff Ilircls p. Kll) also recoiils it from tlie Loner .Vmazons, liut 

 I liave not been able to ascertain on what authority. Wallace certainly did not obtai[i sijecicnen.s 

 anywlicre on the Lower Arnazou.s (of. J'. X. ,S. Land. 1SG7. pp. jtiO-llG). It is aiso to be remembered that 

 none o£ the more recent travellers (Robert, Hoffmanns, Wncthlage) met with N. r. ruiecvia in the Parii 

 district.
