634 DR. H. BURMEISTER ON A NEW DOLICHOTIs.  [ Dee. 7, 
Mr. H. A. Wickham, dated Piquiahiba, near Santarem, Brazil, July 
31, 1875. 
Mr. Wickham said, “It may interest you to know that the large 
blue Hyacinth Macaw (dra hyacinthina) is to be found much nearer 
Santarem than has been hitherto supposed. I have just been for a 
three days’ hunt through the forest covering the tableland south of 
this place towards the Curud river. Along the sides of a water- 
course we traversed, these birds appeared to be quite common, their 
peculiar quavering caw being constantly heard ; but so local did they 
seem to be, that five or six miles further on we neither saw nor heard 
them.” wile 
Prof. Owen read the twenty-second of his series of Memoirs on

1. Description of a new Species of Dolichotis. By Dr. Hrr- 
MANN Burmetster, Director of the National Museum, 
Buenos Aires, F.M.Z.S. 
[Received September 20, 1875.] 
-(Plate LXIX.) 
The genus Dolichotis, one of the best-marked of the family Ca- 
viini, differs strikingly from the rest of the group in the great size of 
its ears. It was founded by Desmarest in 1822, the only known 
specimen having been first described by Azara under the Spanish name 
Liebre patagona. This animal is well known its native country 
under the last name, and is common in the districts of Upper Pata- 
gonia, near the Rio Negro, and in the western provinces of St. Luis 
and Mendoza, but was long rare in European collections. 
The investigations of Darwin, Waterhouse, and myself (Reise durch 
die La Plata-Staaten, tom. ii. p. 422) have given full particulars as to 
its habits, external characters, and anatomy, the last-named part of 
its organization haying been shortly described in my work above re- 
ferred to. : 
Till now no second species has been known; and I was therefore 
surprised on receiving an animal, obtained by Dr. C. Berg, the able 
inspector of the Public Museum, which resembled the Patagonian 
Hare, but which indicated by the still greater size of its ears a new 
species of Dolichotis. 
It is strange that an animal as large as a common rabbit should 
have escaped the notice of scientific men in a country so much visited 
by travellers of late years ; but as this animal lives in a region remote
