Mr. H. Seebohm on the Ornithology of Siberia. 173 
lished, there are two uncertain species which require mention. 
They are:— 
1. Pipreola chlorolepidota of Swainson, above mentioned^ 
which was probably, I think, based upon a female of P. 
sclateri. 
2. A specimen in the Museum of Neuchatel, obtained in 
Peru by Tschudi, and considered by him, as I understand, 
a female of his Ampelis elegans, although not described as 
such. This is certainly not the female of P. elegans, as it 
shows conspicuous white spots on the outer webs of the ends 
of the secondaries. It comes nearer to P. formosa, and is 
probably the female of a species allied to P.formosa, of which 
the male is unknown to us. I am in some doubt whether 
the female specimen from the E-io Napo in my collection, 
which I formerly treated as P. chlorolepidota (P. Z. S. 1854, 
p. 113, et 1859, p. 441, et Cat. A. B. p. 254), belongs to this 
same species or to P, formosa. I trust we may soon obtain 
examples of the male sex of this interesting bird, which may 
help us to solve the question.

During the last few years considerable efPorts have been made, 
principally by Professor Nordenskiold of Stockholm and 
Captain Wiggins of Sunderland, to reopen to European com¬ 
merce the ancient route to Siberia through the Kara Sea. 
Last year (1876) Captain Wiggins left Sunderland on the 
8th of July in the arctic steam-yacht Thames ^ (about 120 
tons), and entered the Kara Sea on the 3rd Aug. He spent 
some time in surveying the coast, and anchored in the gulf 
of the Obb on the 7th of Sept. On the 23rd of Sept, 
he began to ascend the Yen-e-say'*; and on the 17th of 
October he had succeeded in making about a thousand knots 
* In this paper I have endeavoured to spell all the Russian proper 
names phonetically, showing also the syllable upon which the accent must 
be laid, a matter of great importance in the Russian language.
