358 Mr. W. A. Forbes on Eleven Weeks 



Witli regard to the peculiar loud cry of the present species, 

 it may be remembered that, like many other Cracidse, the 

 male bird has a convoluted trachea, the fold (which lies out- 

 side the pectoral muscles) in some cases extending as far as 

 the posterior end of the sternum. 



107. IIallus longirostris. 



My friend Herr Miiller, of Recife, during my absence in 

 the interior, got a specimen of this bird for me, which he had 

 shot in the close vicinity of Recife. 



108. Rallus nigricans. 



A second species of Rail, also brought to me alive at Q,ui- 

 papa, I identified with with this species from Burmeister's 

 description. It fell a victim to rats during my absence. 



Irides bright red; feet dull red; beak yellowish green, 

 greyer at the tip. 



109. Aramides cayennensis. 



Whilst staying at Quipapa some boys brought in for sale 

 a living specimen of this Rail, which they had caught near 

 the town. 



110. Cariama cristata. 



The occurrence of the Cariama in the Sertoes of Per- 

 nambuco is a fact of some interest, as it marks, I believe, 

 at present the most northern limit of this curious genus. I 

 did not myself see the Cariama in the wild state ; but I saw, 

 at Garanhuns, one that had been captured by the Indians 

 near Aguas Bellas, a town some seventy miles further S.W. 

 in the direction of the Paulo Alfonso falls. I was also told 

 that it occurs not rarely in the open country near San Bento, 

 another small town about thirty-five miles north of Garan- 

 huns, and, like Aguas Bellas, also in the Sertoes. The Bra- 

 zilian name of the Cariama is, I may observe, " Siri-ema," a 

 form also used by Burmeister in his elaborate treatise on this 

 bird. " Ema,'' as we shall presently see, is the name given 

 to the Rhea [R. macrorhyncha) , which is found along with the 

 present species in the open plains of the Sertoes, and " Siri " 

 is a diminutive of Indian extraction, the word thus signifying 

 " little Ema."
