1875. | LETTER FROM CAPT. J. MORESBY. 533 
The sketch had been taken from the original at the Grand-River 
Indian Agency, Dakota Territory, while Mr. Hoffman was stationed 
there as Surgeon in 1872. The horn had been used as a charm by 
one of the chiefs of Sioux Indians; and Mr. Hoffman had been in- 
formed by him that both horns of the animal were alike. The one in 
Horn of Antelocapra americana, with double prong. 
a, perforation for cord; 4, artificial edge, cut by wearer. 
question had been perforated and attached to a buckskin thong, and 
in this manner worn about the neck. The specimen had been after- 
wards purchased by the Hospital Steward, who had it in his collection 
still when Mr, Hoffman wrote. 
Mr. Sclater read a letter from Captain J. Moresby, R.N., stating that 
the young example of Casuarius uniappendiculatus presented by him 
to the Society on the 25th August, 1874, had been obtained on the 
29th of May, 1874, on the western extremity of New Guinea, at a place 
called ‘Threshold Bay” in lat. 1° south and long 132° east (ap- 
proximately), about 20 miles to the north of the island Salawatti. 
The statement respecting the origin of this bird given on Dr. Ben- 
nett’s authority (P. Z. S. 1875, p. 84) was therefore incorrect, the bird 
there alluded to by Dr. Bennett under the name Casuarius uniap- 
pendiculatus having been the example of Casuarius beccarii above 
referred to (p. 527), which had been obtained by the ‘ Basilisk’ on a 
previous occasion, 
The following papers were read :—
