20 MR. P. L. SCLATER ON THE GENUS SYNALLAXIS. [Jan. 6, 



remigibus interne nigris : subalarlbus cinnamomeis : gutture et 

 collo antico albu maculatis : long, tota 4 - 5, alee 2*5, caudce 1'9. 

 Hab. Columbia int. 



I have only met with this species in Bogota collections. It appears 

 to be the Siptornis flammulata of Reichenbach ; but I think it very 

 doubtful whether it is the Sittasomus flammulata of Lesson.

Hab. Rio Negro (Natt.) ; Pebas, Peru (Cast, et Dev.) ; Yura- 

 cares, Bolivia (d'Orb.). 



H. v. Pelzeln has kindly sent me his unique specimen of this 

 curious bird for examination. It was obtained by Natterer on the 

 Rio Negro, opposite Boavista, in December 1830. It is rather a 

 strongly formed species, but must, I think, be retained in the genus 

 Synallaxis. 



Among the skins in the Jardin des Plantes are three of this 

 species — an adult and a young specimen obtained at Pebas by 

 Castelnau and Deville, and an adult obtained by D'Orbigny in the 

 province of Yuracares, Bolivia. 



The figure (Plate IV. fig. 2) is taken from the typical example 

 of Natterer. In the young bird the spots below are barely visible, 

 and the throat and neck are suffused with rufous. 



Sect. b. Species pileo dorso concolori, striato aut substriato: alis

 Synallaxis inornata, Scl. et Salv. P. Z. S. 1868, p. 167 (err.). 

 Olivaceo-brunnea : pileo subcristato obscuriore, paulum striato : alis 



extus cum remigum marginibus externis rufis : subtus dilutior ; 

 tectricibus subalarlbus et remigum marginibus internis cinnamo- 

 meis : rostro flavicante, pedibus pallide fuscis : long, tota 5"8, 

 alee 2 - 1, caudce 2*7. 

 Hab. Venezuela, prope urbem Caracas (Goering et Dyson). 

 Mus. Brit, et P. L. S. 



One of Mr. Goering's Venezuelan collections contained a single 

 example of this species, which, however, was erroneously determined 

 by Mr. Salvin and myself as (S 1 . inornata. There is one skin of the 

 same species in the British Museum, also obtained near Caracas, by 

 Dyson, and two in the Jardin des Plantes transmitted by M. Le- 

 vraud from the same locality. 



The nearest ally of the present bird is S. ruticilla, from which it 

 may be distinguished by the want or very slight indication of the 

 white eyebrows, by the red colour of the wings extending over the
