214 Lord Walden on Dr. Stoliczka^s " Observations." 



Chini. In the summer it is said to be more common in Tibet. 

 Hodgson's name Budytes citreoloides is adopted for the Yellow- 

 headed Wagtail, upon the authority, apparently, of Mr. Blyth, 

 as quoted by Dr. Jerdon (B. Ind. iii. p. 873). Wherein 

 Hodgson's species differs from that of Pallas, I have failed to 

 discover. Indian examples agree in every respect with the de- 

 scription given by Pallas (Reise, 1776, iii. App. p. 696, no. 14) 

 of his type specimen, which was obtained on the 26th of 

 April (O. S.) in Siberia, and consequently had not assumed 

 the full breeding-plumage. Pallas remarks that the same spe- 

 cies is to be seen in Russia in spring, at the time when birds 

 are migrating northwards. Dr. Stoliczka has omitted to de- 

 scribe the plumage of his specimens and the exact period of the 

 year he met with them. The bird to which Hodgson gave the 

 names of Budytes calcaratus and B. citreoloides is rarely found, in 

 India, in full black and yellow breeding-plumage ; and although 

 some individuals may breed in the southern valleys of the Hima- 

 layas, yet, from the scarcity of examples in breeding-livery,we may 

 infer that the greater part migrate in the spring further north. 

 Any how, nothing less than a comparison made between a series 

 of Siberian and Indian birds can determine the question ; and 

 even if the Indian bird proves to be distinct from B. citreola 

 (Pall.), it will have to bear the iiiXa oi calcaratus, Hodgs. (1836), 

 which has a priority of eight years over that of citreoloides^, Hodgs. 

 Par us cinereus, Vieill., was observed as far north as West Tibet. 

 Consequently, if we are justified in considering Javan, Cingalese, 

 Western-Indian, Nipalese, Central-Indian, and Afghan indivi- 

 duals as belonging to one species, the range of this Titmouse is 



* Fortunately Pallas's bird escapes having to take tlie specific title of 

 sheltohriuschka, Lepechin {Iter, ii. p. 187, tab. 8. f. 1, 1775 — a work pub- 

 lished one year previously to Pallas's travels), which is given as a syno- 

 nym by Gmelin, Latham, Blyth, and Horsfield and Moore, Lepechin 

 calls his species Der Bachstelze mit clem gelben Bauche, and adds the 

 name above quoted as being that by which this bird is known in Russia. 

 Gmelin (S. N. i, p. 962) latinized the Russian word without adopting it, 

 and hence the origin of the synonym. In the ' Zoographia ' Pallas altered 

 his title to Motacilla citririella ; and Lesson described the species (Traits, 

 p. 422, 1831) under the title of M. aureocapilla. By both these authors 

 the winter plumage alone is described.
