judging from the specimens before me, differs but little from that above described. The young 

 bird from the Ural resembles the adult, but has the upper parts rather greener and clearer in tint 

 of colour. 



When, in 1878, in my article in the ' Birds of Europe ' on Pliylloscopus plumbeitarsus, I suggested 

 that the young bird from Tjubuk, attributed by Meves to that species, was more probably 

 Phylloscopus viridanus, I was certainly not prepared to hear that all the recorded occurrences 

 of P. plumbeitarsus in the Ural, and within the limits of European Eussia, would turn out to 

 be referable to P. viridanus ; but Mr. Pleske, who has recently worked this question out with the 

 greatest care, has proved this to be the case, and he has also shown that Phylloscopus plumbei- 

 tarsus has not been ascertained to occur further west than in Turkestan, and should therefore 

 be expunged from the list of Western Palsearctic birds. He states (Orn. Eoss. ii. p. 178) that 

 both Phylloscopus viridanus and Phylloscopus plumbeitarsus have been mixed up together under 

 the name of P. middendorffi,, but that he has ascertained that of these two only P. viridanus 

 occurs west of the Ural, and that therefore all records of the occurrence of P. middendorffi in 

 European Eussia must refer to the present species. Thus Mag. J. Poljakoff met with it at the 

 Ladscha Lake, in the Olonetz Government ; and Sabanaeff records it from the Government of 

 Jaroslaw. There is a specimen from Kasan Avhich came with the Eversmann collection to the 

 St. Petersburg Museum, and it is found in the Ural, and is said to be most numerous in the 

 Perm Government. Sabanaeff has, Mr. Pleske continues (I. c), " recorded P. viridanus from the 

 borders of the Orenburg Government to Bogoslovsk, and also met with it in the birch-woods of 

 Bashkiria, on the eastern slope of the Ural. In the Perm Government he found it in a garden 

 in the town of Perm, in the Pavdinskisch and Bogoslovskisch Ural, on the east side of the Ural 

 range. Meves met with it in the Perm Government, on the banks of the Kama, opposite the 

 town of Perm, and at Tjubuk, where a male and female were seen feeding their not fully 

 fledged young on the 9th July. Meves, however, wrongly identified his specimens as being 

 P. middendorffi. A specimen obtained by him came into the possession of Mr. E. von Homeyer, 

 who corrected the former erroneous identification of Meves and Dresser, and identified the Ural 

 example as P. viridanus. AVe must not omit to name a male kindly presented to our Museum 

 by Mr. Teplouchoff, and to remark that Prof. Menzbier's notes on the migration-route of 

 P. plumbeitarsus in European Eussia refer to P. viridanus. Thanks to the liberality of 

 Mr. N. Zarudny our Museum received a splendid specimen from the vicinity of Orenburg. 

 Severtzoff speaks of a specimen having been obtained at the mouth of the Ural river in May 

 1861, and the two examples from the Karelin collection in our Museum probably came from 

 Gurjeff. This Warbler appears to be not uncommon on the northern shores of the Caspian, as 

 two specimens, now in the University Museum, were obtained by Prof. Bogdanoff on the Kulaly. 



"With regard to the occurrence of this bird in the Caucasus I can give no positive information. 

 The bird described by Dr. Eadde as P. plumbeitarsus, which was shot at Tiflis on the 29th April, 

 certainly does not belong to that species, but appears, to judge from the description, to be 

 referable to P. viridanus, if not to P. nitidus, which has been several times recorded from 

 the Caucasus. 



" To proceed to the occurrences in the Altai range, I believe that Tschichatscheff 's notes on
