1 have littlo to add to th« remarks on this Hpocios in tlio Birds of 

 North Amuriua, except that the predoiniiiunt Khudo in the back is 

 tlie olive of Hwaintionii ratiier than the reddish of /««<•(»«<•? n«, ns in 

 T. paUasii. I have, however, not mentioned the difference in tiie 

 bill, V, liieh, besides beinj^ sniallcr, is much more deprcHsed, as in 

 AnthuH. The heij?ht of the bill ut the base juHt back of the nostrils 

 in jiaUtiHn is from .17 to .15) of an inch, while in vanuts it is only .15. . 

 The distance from tip of bill to nostril is .35 or .36 ; the lengtli of 

 tarsus, 1.07 to 1.10; the win}?, 3.30 to ,S»48. The clear plumbeous 

 east of the flanks and thijfhH, anil the white crissum of variua, con- 

 trast characteriitically with the rufous tinge of the same jjarts in 

 j)allanu. The legs are rather (hirker and considerably more slender. 



Pallas, in his Zoographia liosso-Asiatica, I, 1831 (?), 4<55, de- 

 scribes a Muscicapa (jultata from Kodiak, an island of the Russian 

 American Archipelago, collected by Billings. This was, in all pro- 

 bability, a young Thrush in the inmiaturc spotted plumage, and if 

 any described North American species, may, from its size and colora- 

 tion, be referred to Turdun nanus, rather than to any other Thru.sh. 

 Should this be substantiated, the name gutlatun must take prece- 

 dence ; but as there is still some uncertainty on the subject, I prefer 

 to make no change at present until young birds of the species can 

 be procured. A youtig T. pallasii shows some rather marked differ- 

 ences from Pallas' description.
