 pi. 6. 



One example from Huan Gulf. 



10. Sterna melanauchen (Temm.). 



One skin, obtained in the D'Entrecasteaux Islands in March, is 

 referable to this species, as Mr. Howard Saunders kindly assures me. 

 Mr. Gould has already recorded its occurrence in Torres Straits 

 (B. Austr. vii. pi. 28), where it was obtained by MacGillivray. 



11. Phalacrocorax, sp. inc. 



A single skin of a young Cormorant, in nearly uniform brown 

 plumage with yellow feet, obtained in Huan Gulf in May. 



6. Additional Notes on Dolichotis saUnicola. By Hermann 

 Burmeister, Director of the National Museum, Buenos 

 Aires, F.M.Z.S. 



[Received May 4, 1876.] 



Since my former description of this new species of Dolichotis *, I 

 have been fortunate enough to have two fully adult living specimens 

 sent to me for examination by a gentlemen who has had them alive 

 in his house at Santiago del Estero. This gentleman informed me 

 that this species is common in the country to the west of that town, 

 its range beginning in the south near the.small town of Chanar, and 

 extending northwards along the borders of the great salina desert as far 

 as Santiago del Estero and the river Dulce, where the country has 

 the same sterile character, but not into the much more fertile region 

 of the Province of Tucuman more to the north. Especially in the 

 vicinity of Posta del monte and of the village of Piedritas near Chanar 

 the animal is very common. The two living specimens, which are 

 now under my inspection, show that my former description was taken 

 from very young specimens of about half their full size, and that 

 this northern species comes much nearer in size to the southern 

 species (D. jjatagonica) than I was formerly led to suppose. 



A fully adult specimen agrees very closely in size and colour with 

 the Patagonian species, only differing slightly in some shades of 

 colour and in shape. The head is somewhat shorter and stouter, 

 more especially the anterior portion from the nose to the eyes 

 (which was already indicated in the skull of the young animal), 

 although the space between the nasals and the intermaxillaries 

 is much longer, this space equalling half the length of the nasals 

 in the northern species, and not more than one third in the soutbern ;
