4. Description of a New Tanager of the genus Euphonia. 

 By Philip Lutley Sclater, M.A., F.L.S. etc. 



(Aves, PI. CXXIV.) 



Mr. Gould having placed in my hands for examination some spe- 

 cimens of Euphonia, which he has lately received from Guatemala, I 

 am enabled to exhibit to the Society examples of both sexes of what 

 I believe to be a hitherto uncharacterized species of that genus. I 

 am no friend to the too frequent practice of calling animals after indi- 

 viduals, but I feel that I shall meet with approbation in this instance 

 if I confer on the present bird the name of one of the most eminent 

 naturalists of the day, to whom moreover I am indebted for nume- 

 rous acts of kindness from the period when I first had the pleasure 

 of his acquaintance. I therefore propose to call this species 



Euphonia Gouldi. 



<? . Supra olivacea, ceneo induta : pileo usque ad oculos cum f route 

 Jiavis : subtus, gida et cervice flavescenti-olivaceis, abdomine 

 medialiter castaneo, hoe colore flavo utrinque marginato ; late- 

 ribus olivaceis flavo mixtis : crisso castaneo : rostro et pedibvs 

 nigris. 



9 . Supra mari similis sed dilutior, fronte et pileo antico rubris : 

 subtus flavescens, abdomine medio cum crisso dilute castaneis, 

 lateribus flavido- olivaceis. 



Long, tota 4*1, alse 2*2, caudse TO, tarsi 0'7. 



Hab. In Guatimala et Mexico Meridionali. 



Gould's Euphonia does not sufficiently resemble any other of the 

 known members of the group to render it liable to be confounded 

 with them. It may, I think, be most naturally placed at the head of 

 the section containing Euphonia pectoralis, E. rujiventris and others 

 (which has been denominated Iliolopha by Prince Bonaparte), and 

 will serve to connect them with the yellow-headed species which pre- 

 cede them in my arrangement. I have suspected its existence for 

 some time, but these examples are the first good ones I have seen of 

 it. I have had for several years in my possession a bird which I 

 now find to be an immature individual of this species ; and M. Salle's 

 collection comprised a single specimen not in very good condition, 

 which he obtained in Southern Mexico. I gave a short description 

 of the latter bird without naming it in my list of his collection (see 

 P. Z. S. 1856, p. 303), but was mistaken (as I now see) in consider- 

 ing it a female. 



This Euphonia is the fourth additional Tanager I have met with 

 since completing the synopsis of these birds given in the Proceedings 

 for last year; the others being Calliste rufigena (P. Z. S. 1856, 

 p. 311), Saltator melanopterus (Pr. Ac. Sc. Phil. viii. p. 361), and 

 Pyranga roseigularis (P. Z. S. 1857, p. 6). The latter bird was 

 long ago described by Dr. Cabot, but at the time of completing my 

 synopsis I had not seen specimens of it.
