1874.] MR. P. L. SCLATER ON THE GENTJS SYNALLAXIS. 13 



My acquaintance with this species was made in 1856 from speci- 

 mens in the British Museum and in Mr. T. C. Eyton's collection 

 I have again examined these examples, and have recognized their 

 identity with Leptoxyura semicinerea of Reichenbach, whose prior 

 specific name is now adopted accordingly. An imperfect skin of 

 this bird in the Jardin des Plantes was obtained by D'Orbio-ny in 

 the Bolivian province of "Valle Grande. ° 



Synallaxis semicinerea is at once recognizable by its pale ashy 

 head and uniform red back, wings, and tail, and in colour is quite unlike 

 any other known species. Both specimens examined appear to have 

 only ten rectrices. Mr. Eyton's skin was purchased of Parzudaki 

 and is labelled " Bahia."

The single example in the British Museum is the only specimen 

 ot this well-marked species that I have met with. It was obtained 

 along with other birds from the Sudbury Museum in 1843, and is 

 said to have been received from " Brazil."
