black. The rings on the body do not extend across the \entrals, 

 which are white, and, like the white interspaces between the black 

 rings, irregularly spotted with black. 



This is a slender species with narrow head, and with the body 

 somewhat compressed. Total length 15 inches, the tail being 4 

 inches. 



6. Descriptions of three new Species of the Genus Synallaxis.

Among the birdskins collected by M. Jelski in Central Peru, and 

 lately submitted to my examination by our Corresponding Member 

 M. Taczanowski, of Warsaw, are specimens of four species of 

 Synallaxine birds which had not occurred in his previous collections, 

 and were therefore not included in my synopsis of the genus, pub- 

 lished in the first part of the Society's ' Proceedings ' for the present, 

 year. What is still more remarkable is, that three of these species 

 (all referable to the Synallaxis proper according to my views) ap- 

 pear to be new to science. Certainly they cannot be referred to any 

 of the fifty-eight species which I have described in the above-men- 

 tioned memoir. The fourth is Leptasthenura andicola (Sclater, 

 P. Z. S. 1869, p. 636, pi. xlix. fig. 2), which I had not met with 

 previously in Peruvian collections, although its occurrence there was 

 by no means unlikely from its having been obtained at a high 

 elevation in the Andes in the neighbouring republic of Ecuador. 



Of the three new species of Synallaxis, with M. Taczanowski's 

 kind sanction, I proceed to offer the following descriptions. 



1. Synallaxis pudibunda, sp. uov. (Plate LVIII. fig. 1.) 



Supra murino-brunnea, in dorso inferiore rufescens ; alis et cauda 

 luride rufis, hujus rectricibus quatuor mediis inpogonio interiore 

 nigricantibus : superciliis indistinctis, capitis lateribus et corpore 

 toto subtus cineraceo-fuscis ; gula media pallide fulva, punctis 

 indistinctis nigris circumdata : hypochondriis et crisso rufescente 

 lavatis : subalaribus et remigum marginibus internis rufis : rostro 

 obscure cornea, mandibula inferiore ad basin albicante, pedibus 

 obscure corylinis : long, tota 5"8, alee 2*1, cauda rectr. med. 2*9, 

 rectr ext. 1*7. 

 Hab, Obraillo, Peru (Jelski). 

 Mus. Varsoviano. 



There is but one specimen of this species, which, however, seems 

 quite distinct from any of those that I am acquainted with. It be- 

 longs to the section with twelve rectrices, and will stand best, I think, 

 near S. modesta and its allies, having a pale fawn-coloured gular 

 patch, round which, on the sides of the face and neck, are indistinct
