1873.] DISTRIBUTION OF ASIATIC BIRDS. 665 



same bird from N.W. Himalayas, presents a most curious fact in geo- 

 graphical distribution, as it is replaced in Nepal and Sikim respectively 

 by Certhia nipalensis and C. discolor, while here, at a distance of 1000 

 miles or more from its nearest known habitat, the same identical 

 form reappears. The solution of this problem will, I think, puzzle 

 far wiser heads than mine ; for though it is easy by an imaginary 

 submergence and reappearance of land to account for almost any thing 

 where islands are concerned, the only reason I can suggest for the 

 occurrence of Certhia himalayana in Moupin is that it is a northern 

 species inhabiting the unknown Tibetan mountains to the north of 

 the Himalaya, and only reaching Cashmere by a circuitous route. 



Several species, such as Trochalopteron blythii, Verr., Paradox- 

 ornis guttaticollis and Allotrius sophicb, differ so slightly from their 

 Himalayan representatives, that I should hardly like to separate 

 them without a large series for comparison ; but the many other 

 fine species which I have noted below are more than sufficient to 

 support the scientific fame of their discoverer and describer, MM. 

 David and Verreaux, to whom I am much indebted for the kindness 

 with which they have allowed me to examine and compare these 

 unique specimens in the Paris Museum.
