ninth, and in one only equal to the ninth. In several the fourth and fifth primaries are equal 

 and the longest, whereas in others the third and fifth are equal, the fourth being a trifle longer ; 

 whereas in my Siberian bird the third and fifth are equal, and the fourth a trifle longer. I have 

 only had an opportunity of examining two Siberian specimens, which is not sufficient to decide 

 the question ; but inasmuch as Mr. Pleske, who has examined both Indian and Siberian 

 examples, does not separate the two forms, I think that it is tolerably safe to unite them. 



Although the present species cannot well be separated generically from the Phylloscopi, yet 

 in its general habits it approaches nearer to the Kinglets than the other members of the genus. 

 Dr. Taczanowski remarks that " in habits, mode of life, and nidification this bird shows affinity 

 to our species of Bequlus ; whereas P. superciliosus, which has been placed by many ornithologists 

 in the same genus with this species, is a true Willow- Wren." 



It frequents pine-woods and those of mixed pine and birch in hilly districts, sometimes 

 ranging in the mountains as high as the border of tree-growth, and it is also to be met with in 

 the bush-covered valleys. Godlevski says that its call-note, which is seldom repeated, may be 

 rendered as tsii, shriller and more prolonged than the call-note of P. superciliosus, and the song 

 of the male, which is continued for hours without intermission, s melodious and varied and of a 

 very high order. Dr. Dybovvski also writes (J. f. O. 1872, p. 361) that " its note is melodious 

 and powerful, and its song varied and sweet, and so loud that it rings through the forest, and 

 is astonishing as coming from so small a bird." Mr. W. E. Brooks, who has had frequent 

 opportunities of hearing the call-note of this Warbler, says (Ibis, 1869, p. 236) that "it is very- 

 different from that of P. superciliosus, and is extremely shrill, feeble, and tinkling. There are 

 two notes in the call, the second considerably above the first, D to F sharp ; and in uttering its 

 call the bird keeps the two notes quite distinct, and not slurred into each other, like the call of 

 P. superciliosus." 



Referring to the nidification of the present species in Eastern Siberia, Dr. Dybowski writes 

 (J. f. O. 1872, p. 361) as follows: — "Although not uncommon, we did not find its nests in 

 Kultuk, but found them in Petrovsk, beyond the Baikal, on the left bank of the Selenga River. 

 The nests were placed on young pines or old moss-covered cedars on the branches near the stem, 

 three to four metres high, and were neatly constructed of fine grass-bents and green moss, oven- 

 shaped, the opening being towards the trunk of the tree, and lined with feathers and horse- or 

 cattle-hair; the nest is also higher than it is broad. About the middle of June the female lays 

 five or six eggs, and commences sitting directly the first egg is laid, so that in the same clutch 

 one finds quite fresh as well as incubated eggs. The female sits close, and can easily be caught 

 on the nest. While she is sitting the male perches on the top of a tree and sings incessantly. 

 The eggs are white, with dots and small spots of violet, ash-grey, and red, which are chiefly 

 collected so as to form a not very close wreath round the larger end, and measure from 14 by 11 

 to 15 by 10 - 5 millimetres, being broadest in the middle." 



Captain Cock, who found it breeding at Sonamerg, four marches up the valley of the Sind 

 River, late in May and early in June, says that its nest is placed on the outer end of the branch of 

 a fir tree at from 6 to 40 feet elevation, and sometimes on a small sapling pine where the junction 

 of the bough with the stem takes place. The nest is partially domed, the outer portion consisting 

 of moss and lichen, so arranged as to harmonize with the bough on which it is placed, and lined
