For the sake of comparison I append the measurements of Sp. jardinei. 



2 c?c? ad. from Ecuador. Wing 70, 68 ; tail 49, 46 ; bill 13, 121 mm. 



3 cf c? from Bogota coll. Wing 67, 69 ; tail 46, 49 ; bill 12, 13 mm, 



1 S jr., from Marcapata, S.E. Peru. Wing 69 ; tail 49 ; bill 1 3 mm. 



1 S jr., from Bolivia (Mus. H. v. Berlepsch). Wing 69; tail 50 ; bill 13 mm. 



llaploipiza and Spodiornis are doubtless ver}' near allies, and must be placed 

 close together, not far from Pkrt/gilus ; the pattern of coloration in tlie females is 

 similar to that of P. unicolor, a further proof of their near relations. The 

 latter species, however, cannot be included in the same genus with Haplospiza 

 unicolor, as has been done by several American authors, for the shape of the wing 

 is widely different. 



4. Crithagra hilarii Bp. = Sicalis a. arvensis (Kittl.) 



Frinrjilla arvensis Kittlit/,, .l/c/K. Acad. St. Petersb. (sav. eir.) ii. (1835) p. 134 (Chili).* 

 Crithagra hilarii Bonaparte, Consp. Av. i. (1850) p. 521 (Mus. Paris : ex Brazil.). 



Mus. Paris, skin : " No. 27. Mr. St. Hilaire, 23. mai 1821. Crith. hilarii Bonap. 

 (typ.)."— Wing 73 ; tail 53 ; bill 19 mm. 



This is by no means .S'. a. minor (_'ab., with which Bonaparte's name has been 

 doubtfully associated by Sharpe,t but belongs to the large race of S. arvensis found 

 in South Brazil. The original specimen agrees perfectly with another from Rio 

 Grande do Sul (Mns. Berlepsch) ; in both there are no white markings on the tail. 

 Unless the South Brazilian form be separable from the typical Chilian birds, 

 C. hilarii is to be considered as a synonym of S. a. arvensis. 



It may be added that the type came from South Brazil : S. Paulo or Parana, 

 where, according to the registers of the Paris Museum, M. Auguste de St. Hilaire 

 was collecting during the year 1821. 



I hope to discuss the various forms of the S. arvensis group on a later occasion. 



5. Buarremon baeri Oust, should be Compsospiza baeri (Oust.) ! 



Buarremou Baeri Oustalet, Bull. Mus. Paris x. (1904) p. 43 (Lagunita, Tucuman). 



This bird, one of Mons. G. A. Baer's discoveries in the district of Tucumdn, 

 belongs by no means to the genus Buarremon, as supposed by M. Oustalet, but 

 represents a second species of the genus Compsospiza, proposed by Count Berlepsch* 

 for a remarkable Finch of the highlands of Bolivia, C. garleppi. The type of this 

 species having remained unique in the Count's magnificent collection, the discovery 

 of a second form was of great interest. 



C. baeri (Oust.) agrees with the type of the genus not only in the shape of the 

 bill and in the form of the wings and tail, but presents also a close resemblance in 

 coloration. The distribution of the ferruginous aud grey colours on the top and 

 sides of the head is absolutely alike in both species, but C. baeri differs at once by 

 having only the throat aud foreneck aud the under tail-coverts ferruginous, while 

 the remaining underparts are pale slaty grey with a slight olive hue on the sides. 

 Moreover, the slate grey of the upperparts is paler, the edge of the wing slate- 

 grey (not ferruginous), and there is no trace of the white apical margins on the 

 two outer tail-feathers. C. baeri is also much smaller.
