Besides the.se sjiecimens, I have examined an adnlt male from Rio de Janeiro in 

 Count Berlepsch's collection, and another from (!ayaba, Mattogrosso,* obtained by 

 Natterer, in the Vienna Mnsenm. 



0. c. maximiliaiii is a very close ally of 0. c. crassirostris (6m.), and takes 

 its place in Southern Brazil. The males differ from those of the typical race by 

 averaging larger, and by having the axillaries and under wing-coverts broadly 

 edged with black. Specimens of 0. c. crassirostris from Cayenne, Surinam and 

 British Guiana (Aunai) have a mnch smaller bill, as well as shorter wings and 

 tail. Those from Trinidad (Seelet) and the Orinoco valley, however, are scarcely 

 smaller than 0. c. ma.rimiliani, and the bill is quite as large and stont as in the 

 latter. Two adult (SS from the upper Rio Negro (Lamalonga, Marabitanas) have 

 the strong bill of the Orinoco and Trinidad birds, but in size they agree with the 

 Guianan ones. The female of 0. c. maxiiniliaiii differs from 0. c. crassirostris by 

 its ratlier darker and less rnfescent upper parts, and by having the axillaries and 

 under wing-coverts more buff (less whitish). 



0. c. maximiliani is rather scarce in collections, and its range very imperfectly 

 known. Prince Wied met with it on the Rio Espiritn Santo, and near Vifoza and 

 Caravcllas in the south-eastern portion of the state of Bahia. Natterer obtained an 

 adult male at Cuyaba, Mattogrosso, and Dr. Allen f records three specimens, 

 obtained by Mr. H. H. Smith near Chapada, in the same province. Count 

 Berlepsch possesses, as mentioned above, an adnlt male from Rio de Janeiro, whence 

 there are also two skins in the British Museum.

 These specimens, which agree perfectly with a topotype from Chapada (Brit. 

 Mns.), differ from true <S'. ;. ictericus (Lcht.) ex Rio, S. Paulo, Rio Grande do Snl, etc., 

 by rather shorter wings, clearer yellow under-parts and by having the yellow 

 basal portion of the tail less extended, this being especially noticeable on the 

 median rectrices. The thighs are pale yellow as in S. i. ictericus.
