510 MKSSRS. SCLATER AND SALVIN ON [June 3, 



We refer Mr. Salmon's skins to the large form of M. bonariensis 

 thus determined hy Cassin. M. atronitens, Cab., of Guiana, is not 

 the same, as supposed by Cassin, but a smaller species, of the same 

 size as M. bonariensis.

 and dark brown: axis 1*22, diam. -82. (See Plate XLI1I. fig. 4.) 



" A restless bird, seldom seen alone, but in small parties of six or 

 eight. In the breeding-season, however, its habits are solitary. 

 The nest is composed of large dead leaves and sticks, and is placed 

 loosely in the fork of a small tree." — T. K. S.

" Has much the habits of the English Jay, being ever on the 

 move and seldom silent, except when near its nest or when at 

 mischief. It robs the Indian corn-fields before the grain is ripe, 

 but at other times subsists on grubs and insects. The nest is made 

 of sticks and roots, and is placed in a high bush. The number of 

 eggs is four." — T. K. S. 



150. Cyanocorax affinis, Pelzeln; Scl. Cat. A. B. p. 45;

"The nest is composed of sticks; and all I have seen have been 

 placed with considerable skill in places difficult to find, generally a 

 good way out on a branch. Though a noisy bird at all other times, 

 it is usually quiet when near its nest," — T. K. S.
