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 Rio 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 efforts 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.
