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

 guese, is Sirizinho ; its habits, together with those of the others 

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

 paper on the LanJadm, 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 which 

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

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

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

 difference, as has been pointed out to me 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.
