432 LETTER FROM MR. W. H. HUDSON. [June 24, 
this country by the captain of one of the Union Steamship Com- 
pany’s vessels. It fed well, principally on raw meat pounded small, 
in the same manner as the American Ant-eaters (Myrmecophaga 
jubata), two specimens of which, obtained in October and November 
1867, were still living in good health in the Society’s Menagerie. 
Mr. P. L. Sclater exhibited some very fine specimens of Snakes, 
forwarded to the Society by Mr. George Wilks, of Buenos Ayres, 
C.M.Z:S. These had been determined by Dr. A. Giinther as Hete- 
rodon @orbignyi (Giinther’s Cat. of Colubrine Snakes, p. 83) and 
Euophrys modestus (ib. p. 139). 
Mr. W. T. Blanford, C.M.Z.S., exhibited specimens of the head 
of a Rhinoceros (Rhinoceros keitloa?) and of an Alian’s Wart-hog 
(Phacocherus eliani), obtained by him during the late Abyssinian 
expedition, and called attention to the fact that the incisors were 
permanent in both jaws of the latter, a fully adult individual. 
Mr. Blanford also exhibited, and made remarks upon, some skins 
of Hyraces obtained by him in various parts of Abyssinia. 
Mr. Blanford exhibited specimens of three very rare Indian birds, 
viz. Trocalopteron fairbanki from the Anamullay Hills, Prinia 
adamsi (with the nest) from near Ahmednuggur, and Aleippe brucei 
from Mahableshwar. 
Mr. Howard Saunders, F.Z.S., exhibited some eggs of the Fla- 
mingo (Phenicopterus antiquorum), and the skull and skin of the 
Spanish Lynx (Felis cervaria), obtained by him in the neighbour- 
hood of Seville during a recent visit to Spain. 
The Secretary exhibited, on behalf of Mr. King, and made re- 
marks upon, some drawings by Mr. Tuffen West, illustrating the 
development of Hippocampus annulosus and H. brevirostris. 
An extract was read from a letter addressed to the Secretary by 
Mr. William H. Hudson, dated Buenos Ayres, April 30, 1869. 
Alluding to the paper by Messrs. Sclater and Salvin on birds col- 
lected by him near Buenos Ayres (P. Z. 8. 1868, p. 137) Mr. 
Hudson observed, ‘‘I regret to find that I have made so great a 
mistake as to mark as females two of the three black-plumaged Silver- 
bills (Lichenops perspicillatus, 1. c. p. 141). This was pure care- 
lessness, as all the black-plumaged birds I have ever opened were 
males, and the red females. I have watched them pairing and 
building their nests, and am therefore quité positive they are male 
and female, though the country-people here regard them as of differ- 
ent species.”
