This 8j)ecte8 is evidently out of place in the genns SporophHa,nx\<\ seems best 

 referred — for the present at least — to Gatamenia, althongh its hill, in comparison 

 to C. analis, is laterally mnch more compressed, with the cnlmen slijrhtly ridged 

 instead of being distinctly rounded. The np[)er mandible, however, is very nearly 

 as depressed as in C. analis. 



C. ohscnra (Lafr. & D'Orb.) ranges from N.W. Argentine (Salta) through 

 Eastern Bolivia (("hiiinitos, Santa C'riu dc la Sierra, Oraeja) and Peru (Paitay- 

 pampa, Tarapoto, Vina, Hnaiuachnco, Callacate) to Western Ecuador (Chimbo, 

 C'ayandeled, Paramba).

Wing G8 ;tail 66; bill 12 mm. 



This specimen, which is undoubtedly the type of Bonaparte's description, 

 belongs to the s|)ecies commonly called P. agsimilis Cab., and agrees pretty well with 

 a c? ad. from Sao Lonren(,-o, Rio Grande do Sul, H. von Ihcring coll. in the Paris 

 Mnsenm. But being in rather fresher plumage, it is everywhere brighter, 

 the mantle more decidedly brownish, the npper part of the head washed with 

 olive-grey, etc. Above the eye and auricular region there is a broad white 

 superciliary sti'pe; throat and loreneck are pale greyish buff, middle of breast 

 and abdomen I.iigely white ; sides of body and crissnm, as also the whole of the 

 lower rump, including the upper tail-coverts, })right cinnaraon-rnfons : only thetwo 

 outerniust pairs of rcctrices ti])|)ed with wliite, etc. 



Bonaparte's name having priority must supersede the term nsmmilis Cab. 

 ( 'abanis' statement that P. cabanisi is well characterised by lacldng the rufons 

 colour on the rump. 1 am unable to understand, for Bonaparte in the original 

 description expressly says : " nropygio, lateribns crissofpie fnlvo-castaneis." 



P. cabanisi Bonap. ranges from southern Sao Paulo (Ytararc), through Parand, 

 and liio Grande do Sul to Paraguay and the Argentine provinces of Misiones and 

 Entrerios.*

Wing 81, tail 84, bill 17i mm. 



This is quite a yonug bird, mostly covered with the fluffy feathers of the 

 nestling plumage ; only on the shoulders (lesser wing-coverts) and here and there 

 on the back some isolated feathers of the adult dress are just coming out. The 

 large, thickish bill, and the strong legs with long toes, leave no doubt as to its 

 being a pullus of Ember/iagra platensis.
