A NEW TANAGER FROM SURINAM. 



BY THOMAS E. PENARD. ^ 



The little town of Lelydorp, formerly known as Kofidjompo, 

 situated in the Para district, about seventeen kilometers from the 

 city of Paramaribo, Surinam, has already yielded several new and 

 interesting forms of birds. To their number I now add another, 

 a tanager, which has never before been reported from Guiana 

 and which differs sufficiently from its nearest ally in Peru to 

 warrant subspecific separation. I propose to name it 



Tanagra chrysopasta nitida, subsp. nov. 



Tij'pe, adult d", collection of T. E. Penard, no. 2028 (now Museum of Com- 

 parative Zoology, no. 93,415), from Lelydorp, Surinam, 7 September, 1921; 

 collected by T. E. Penard. 



Subspecific characters. — Similar to Tanagra chrysopasta chrysopasta (Sclater 

 and Salvin) of Peru, but decidedly smaller; under parts brighter and clearer 

 orange-yellow; middle of breast and belly without any trace of olivaceous; 

 cap more bluish, less cinereous; bill dark plumbeous; feet very small and 

 black, not brownish.

Remarks. — This new tanager is the Surinam representative of 

 the Golden-bellied Euphonia of Peru. It is distinguishable at a 

 glance from typical chrysopasta by its diminutive size. The feet 

 especially are much weaker, being no larger than those of Tanagra 

 finschi (Sclater and Salvin) or Tanagra minuta (Cabanis). From 

 the upper breast to the under tail-coverts it has a wide area of 

 bright orange-yellow without any admixture of ohvaceous, giving 

 the entire bird a much brighter appearance than its Peruvian ally. 



The species has not previously been recorded from Surinam 

 and is not known to occur in either British or French Guiana. 

 My brothers, F. P. and A. P. Penard (Vog. Guyana-, vol. 2, p. 

 428, 1910), hst the species and state that they have no knowledge 

 of its occurrence in the Guianas, but have reason to think it does 

 occur there.
