This Ground-fincli is one of the many Mexican species in the Berlin Museum, named but 

 never described by the late Professor Lichtenstein. Although discovered probably some thirty 

 ,, or forty years ago, it was not characterized until 1851, when Dr. Cabanis gave a short 

 description of it in a foot-note to the first volume of his " Museum Heineanum," from a 

 . specimen stated to have been obtained at Eeal- Arriba in Central Mexico, and placed it in the 

 genus Atlapetes. It is very difiicult to define the exact limits between the nearly allied forms 

 of Ground-finches denominated Atlapetes.^ Pyrgisoma^ Pipilo and Chaviceospiza, but it seems 

 better to associate the present species with Pyrgisoma biarcuatian., as subsequently suggested hf 

 Dr. Cabanis.* 



We have not seen specimens of Professor Baird's Pyrgisoma xanthusi lately described by 

 Mr. Lawrence from examples obtained by Xanthus in the plains of Colima in Western Mexico, 

 but have little doubt, that it must be referred to P. ruhricatuvi, the more so as the author 

 appears to have altogether overlooked Dr. Cabanis' description of the latter. The only species 

 of Pyrgisoma at all resembling the present bird in colouring is the ti-ue P. Tcieneri of Bonaparte, 

 of which we propose to give a figure in our next number. But it should be recollected that, as 

 we have already shewn, f there has been a series of errors respecting this latter bird, and that 

 the species called P. kieneri by Mr. Lawrence is our P. cabanisi. 



During his recent travels in Southern Mexico M. Adolphe Boucard obtained specimens of 

 P. rubricatum at Atlisco in the highlands of the State of La Puebla. A pair of these are now 

 in Messrs. Salvin and Godman's collection, from the male of which our figure has been taken,
