Skins from lj;ihi;i (Wuclierer, Brit. Mnsenm), aud Cliiiiuitos in Eastern 

 Bolivia (D'Orbignj-, Paris Museum), are in every respect similar to those from 

 Goyaz. 



Cf. my remarks in Ahhandl. Ahml. Wissensc/i. Miinchen KI. ii. BJ. xxii. 3.

Agrees in every particular with the type which was obtained in the same 

 locality. In Nov. Zool. xiv. 1907, pp. 8-9, I gave a review of the geographic races 

 of S. columbiaua, to which I have nothing to add.

With a consideralile scries from various loi-alities before me I can recognise, 

 east of the Andes, three geograj>hic forms of this group.

 (Reiuliardt) ; Rio Grande do Snl : Tarjuara (Ihering), etc. 



N.l>. — I am unable to see constant differences between specimens from 

 Chili aud Argentine and others from Brazil. Crithagra hilarii Bp. was based 

 on an example from Southern Brazil (cf. JSoc. Zool. xiii. 1906. p. 309). Skins 

 from different localities measure as follows :
