The name which is given tor this bird, in Brazil, by the Portu- 

 guese, is Sirizinho ; its habits, together M^ith those of the others 

 here described, are the same as mentioned by Mr. Swainson in his 

 paper on the Laniadce^ in the last number of this Journal. I have 

 designated this species by the name of that gentleman, whose ob- 

 servations have thrown so much light on this family*

I had originally conceived that my specimen was the first whicli 

 had been brought to England ; but I find a second in Mr. Mac 

 Leay's collection ; and which, although it diffiers in some points 

 from my bird, appears to belong to the same species. Its chief 

 difference, as has been pointed out to n»e by Mr. W. S. Mac Leay, 

 consists in the pectus and abdomen being less white, and more of 

 a lead colour than those of my bird ; the spots also on the head 

 are white, without any fulvous appearance, and the mandibles are 

 altogether black. The native name of this bird is Choca.
