10 MR. P. L. SCLATER ON THE GENUS SYNALLAXIS. [JaU.fi, 



Of this Synallaxis I was for some time inclined to recognize two 

 forms, a northern (S. albigularis) and a southern representative (S. 

 albescens). Further investigation, however, has convinced me that 

 it is better to reunite these, and to regard the whole as belonging to 

 one rather variable species. 



7. Synallaxis hypospodia, sp. nov. 



Fusca: pileo, nisi infronte et alarum tectricibus extus rufis : subtus 

 pallide cinerea, gutturis plumarum apicibus et ventre medio albis : 

 hypochondriis et crisso fuscescentibus : cauda plumis latis,fuscis, 

 apicem versus obscurioribus : long, tota 5*7, alee 2*2, caudce 3. 

 Hab. in Brasil. merid. prope Bahia (Wucherer). 

 Mus. P. L. S. et S.-G. 



This form is common in collections from Bahia, but cannot be 

 referred to any described species. From S. albescens it differs in 

 the ashy plumage below, and from S. subpudica in its shorter and 

 broader tail-feathers. S. pudica is nearly uniform dark cinereous 

 below, and has more extended red on the outer wings. 



8. Synallaxis subpudica, sp. nov. 



Fusca : pileo, nisi in fronte, cum nucha, tectricibus alarum et remigu 

 bus extus ad basin rufis: subtus pallide cinerea, gutturis plumis 

 basin versus nigricantibus, hypochondriis et crisso fusco perfusis : 

 cauda elongata, fusca unicolori : long, tota 6'5, alee 2'2, caudce 4*2. 



Hab. in Columbia int. 



Mus. P. L. S. et S.-G. 



I have two " Bogota " skins of this form ; and a third is in the 

 collection of Salvin and Godman. I was at one time inclined to refer 

 it to the young of S. pudica, but cannot satisfy myself that this 

 would be correct. The distinguishing feature of the species is the 

 long tail (measuring from 4 - to 4'4) and the narrowness of the 

 rectrices. The colour below is not uniform dark cinereous as in S. 

 pudica, but more nearly resembles that of S. hypospodia, being pale 

 cinereous, with the throat-feathers dark at their bases and silvery 

 white at their tips, and the middle of the belly nearly white.

I originally established this species on a Bogota skin, from which 

 Fraser's Ecuador specimens will hardly bear separation. The Panama 

 and northern skins (S. nigrifumosa, Lawr.) are generally rather
