at its upper termination. The bend of the wing and a rather broad margin of the outer web 

 of the outer primary are white. The legs and feet are yellowish-olive, and the lower naked portion 

 of the tibia and the front of the tarsus are described as coral-red in the living bird, but this 

 colour fades away very much in the dried skin. 



Azara, the original discoverer of this species, describes it in his well known work on the 

 birds of Paraguay as the " Focha de ligas roxas," from the red markings on the legs. Azara 

 met with it in the neighbourhood of Buenos Ayres. Professor Burmeister tells us that it is 

 generally distributed over the lagoons of the Argentine Eepublic, and that he obtained 

 specimens near Mendoza and again near Parana. In Southern Brazil the same author, as quoted 

 by Hartlaub, gives the province of Sta. Catherina as a locality for this species, but it does not 

 seem to occur much further north — not being mentioned by Prince Max and other authorities 

 upon Brazilian Ornithology. 



In Chili Fulica armillata appears to be the commonest of the three species, which, according 

 to Herr Landbeck, are so widely distributed and so numerous in the fresh waters of that 

 country. Herr Landbeck has given us an excellent description of the bird, and many details 

 as to its habits and history, but has unfortunately misidentified it with Gay's Fulica chilensis, 

 which we have already shewn is the same as Tschudi's F. ardesiaca. In Southern Chili, Herr 

 Landbeck informs us, this species and F. leucoptera are migratory, or at any rate leave the lakes 

 in the winter, and keep more about the river-banks. In Northern Chili, however, this is not the 

 case, the lakes there not being swollen by a rainy season. 



We have examined the specimen in the British Museum upon which Mr. George Gray 

 founded his MS. name F. frontaia, and believe it to be merely an individual of the present 



species with the head- shield extraordinarily developed, as shewn in our figure. We also think it 

 probable that Fulica gallinuloides of King is referable to this same species, of which there are 

 Patagonian specimens (obtained by D'Orbigny) in the Paris Museum. 



Our figure of this Coot, which is reduced to half the size of nature, is taken from a Chilian 

 specimen collected by the late Mr. Bridges in August, 1862, now in the Derby Museum, 

 Liverpool. We have to record our great obligations to Mr. T. Moore and the authorities of 

 that Institution for the loan of this and other examples of the same group of birds. 



August, 1868.
