1 . Synallaxis prDicA. 



Murino-hrunnea, alarum remigibus et eauda obscurioribus ; pileo 

 cum. fronte et alarum tectricibus omnibus riijis : subtus cine- 

 rascens, ventre imo albicantiore, lateribus brunnescentibus : 

 rostro superiore nigricante, inferior e plumbeo ; pedibus validis, 

 nigris ; cauda elongata, rectricibus decern. 



Long, tota 7 0, alfe 2" 6, caudae 4'0, tarsi O-Q.*). 



Hub. lu Nov. Granada int. 



This species is allied to Sijnallaxis fuliginosa, and of the same 

 form, but easily distinguishable by its red head. From S. elegans 

 (also from New Granada) it differs in its earthy-brown tail and cine- 

 reous colour below. The single specimen in the British Museum is 

 a "Bogota" skin. I have likewise an example in my own collection, 

 received from MM. Verreaux of Paris. 



2. Synallaxis stictothorax. 



Murino-briinnea, uropygio rnfescente ; alis caudaque intus nigri- 

 canti-brunneis, extus rufo late linibatis ; superciliis a fronte et 

 lateribus cei'vicis albidis, nigro obsolete punctatis : subtus 

 alba, lateribus et ventre imo rufescentibus ; pectore toto maculis 

 triangularibus nigricantibus asperso : rostro nigro, basi alba, 

 pedibus fuscis. 

 Long, tota 4"75, alse 2*0, cauuse 2'2.5, tarsi 0*75. 

 Hab. In rep. Equator. 



I first noticed a specimen of this Synallaxis in Sir William Jar- 

 dine's collection. The British Museum contains an example trans- 

 mitted from Guayaquil by Mr. Barclay. The species is not very like 

 any other Synallaxis that I am acquainted with, and may be distin- 

 guished easily by the arrow-headed or triangular spots on the breast, 

 which are partly continued up the sides of the neck, and of which 

 there are also some faint indications on the superciliaries. 



3. Synallaxis scutata. 



Supra mui'ino-brunnea ; dorso toto, alis extus et cauda riifs ; 

 superciliis ante oculum albis, post oculum magis cinnamomeis ; 

 remigum parte interna nigricante : subtus alba, pectore cinna- 

 momeo lavato, plaga distincta ([uadrilaterali in cervice antica 

 nigra: rostro plumbeo, basi palUdiore ; pedibus pallide bi'ttnneis. 



Long, tota .5vo, alse 2'2;'), caudic 2'7"), tarsi ()'8. 



Hub. In Brasilia. 



I have as yet only seen one specimen of this distinct species, which 

 is in the British Museum.
