364 DR. HERMANN BURMEISTER ON THE [Mar. 5, 



amples of eight species, of which, in the interests of science, I think 

 it advisable to record the names and exact localities.

2. Epomophorus macrocephalus, Ogilby. Benguela. 



3. Epomophorus yambianus, Ogilby. Benguela.

4. Synopsis of the Lamellirostres of the Argeutiue Republic. 

 By Dr. Hermann Burmeister, F.M.Z.S. 



[Eeceived January 22, 1872.] 



The tribe of natatorial birds named Lamellirostres, from the 

 peculiar structure of the sides of the bill, which are furnished at the 

 edges with small perpendicular corneous lamellae, is very numerously 

 represented in the vast territory of the Argentine Republic. As the 

 list of species named in my travels through that country (vol. ii. 

 p. 512 et seq.) is not entirely complete, and as I am now, after a 

 residence of ten years in Buenos Ayres, better acquainted with the 

 geographical distribution of many of the species than at the time 

 of my first publication, I have thought it would be useful to prepare 

 a second synopsis, giving additional remarks on most of the species, 

 and correcting some of my former views from new observations. 



I. Ph(ENICOPTERINjE. 



1. Phcenicopterus. 



1. Phcenicopterus ignipalliatus, Is. Geoff. Mag. de Zool. 

 1832, Aves, pi. 2 ; Burm. Reise, ii. p. 512. 



This Flamingo is common on the lagunes in the southern parts of 

 the pampas of the Republic. I have obtained it at Mendoza and at 

 Buenos Ayres. As I have already stated in my ' Reise,' the colour 

 of the base of the bill is not rose-colour but white, and the legs of 

 young birds are yellowish, with bluish-red articulations, but greenish 

 grey in the old birds, with darker reddish articulations and toes. 



2. Phcenicopterus andinus, Philippi, Reise durch die Wuste 

 Atacama, p. 164, pis. 4 & 5. 



This well-marked species is found also in the north-western 

 extremity of the Republic, on the lagunes in the eastern valleys 

 between the Cordilleras and the adjacent mountains, and has been 

 observed there by one of my countrymen, Hr. Schickendantz.
