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



entirely antarctic bird, as its name imports ; and its range extends 

 from Terra del Fuego to the inlet of Santa Cruz, where, I have 

 been informed by a friend, this bird is found every year. 



My distinguished countryman, Prof. R. A. Philippi, of Santiago 

 in Chile, has published (in conjunction with L. Landbeck) iu 

 Wiegmann's ' Archiv' (1863, i. p. 187 et seq.) a valuable synopsis of 

 the Chilian species of Bernicla, to which I refer for further in- 

 formation. 



7. Bernicla Antarctica, Gmel. ; Burm. Reise, ii. p. 514; 

 Phil. Wiegm. Arch. 1863, i. p. 199. 



This species is never seen in the northern districts of Patagonia, 

 but only in the south near the Straits of Magellan, going in the 

 winter to the inlet of Santa Cruz. My former notice (in my Journey) 

 that B. antarctica is found on the Sierra Tinta is an error caused 

 by my having taken the following species (which was known to me 

 at that time only by the description of my son) for B. antarctica. 



8. Bernicla dispar, Philippi, Wiegm. Arch. 1863, i. p. 190. 2. 



Bernicla magellanica, Cassin, Gilliss' Exped. ii. p. 201, pi. 24. 



To this species must be referred my notice of a Goose living in the 

 south of Buenos Ayres on the Sierra Tinta, near Tandil, and the 

 adjacent country. The full description of Professors Philippi and 

 Landbeck renders it unnecessary for me to add any thing further. 

 I can only now extend the habitat of the species more to the south, 

 having received both sexes from El Carmen on the river Negro, 

 where this Goose is common in the summer, proceeding to the 

 northern districts in the winter. 



9. Bernicla poliocephala, Gray. 



Bernicla inornata, Des Murs, in Gay, Faun. Chil. i. p. 444. 

 Bernicla chilo'ensis, Phil. & Landb. Wiegm. Archiv, 1863, i. 

 p. 195. 



This beautiful Goose, the smallest of the species of our country, 

 was described by Des Murs as the female of the Anser inornatus of 

 King, which is, according to the very probable opinion of Philippi 

 and Landbeck, the young of Bernicla magellanica. Therefore they 

 describe the species under the new name of Bernicla chilo'ensis. But 

 this name is by no means suitable, because the bird lives also on the 

 continent, and its range extends over the whole of Patagonia, where 

 it is one of the most common Geese. Both sexes are nearly alike 

 in colour and form, but the colours of the males are more brilliant, 

 and the females have numerous black semicircles on the reddish 

 brown colour of the neck, breast, and commencement of the back. 

 The full description of this bird given in Wiegmann's ' Archiv' 

 renders unnecessary any further remarks from me. I received the 

 bird from El Carmen, Bahia Blanca, in the vicinity of Dolores, 

 where it is not uncommon in the winter.
