to say whether other specimens were or were not seen else- 
where and mistaken for this latter bird. [G. iJ.] 
This is^ I believe, a very rare birdj as this is the only 
specimen I have ever seen. I am by no means clear about 
this species. Gould gives the bill as very small_, whereas 
in this specimen it is very large, much more like the bill of 
H. pallasi as figured by Gould himself and in the ^' Fauna 
Japonica.^-* The bird is clearly distinct from both the pre- 
ceding speciesj but I confess it appears to me more like 
H. pallasi than Gould's figure of H. sordida. The type 
specimen of this latter should be re-examined. In our bird 
the bill is 07 at front; tarsus, 1-2 ; wing, 4. \_A. O. H.]

The Blue Rock Thrush was only met with in Ladak, 
and there only in the upward journey in June and July. 
Solitary individuals were seen throughout Ladak west of 
Le, at Shergol and other places, near streams and hopping 
about amongst rocks ; but in Dr. Cayley^s garden at Le 
they were in considerable numbers, feeding on caterpillars 
on the poplar-trees and hopping about on the grass. None 
were met with on the return journey ; they had then doubt- 
less migrated lower down. [G. H.~\ 
Most probably they breed in Ladak. I have hitherto 
failed to find their eggs, both in the plains of India, which 
they desert as soon as the hot season sets in, and in the 
lower ranges of the Himalayas south of the first snowy 
ranges. It is curious that I obtained a specimen of this bird 
in May at Mount Abu. Can it breed there ? [A. O. H.] 
351 {bis). Monticola saxatilis (Linn.). 
A young male of this species was obtained at Shahidulla, 
in Hill Yarkand, on the 21st September. It was a bird of 
the year. The following dimensions are on the ticket : 
Length, 7*5 ; expanse, 14 ; tail from vent, 2*75 ; wing, 4*5 ; 
foot, greatest length, 1*5 ; greatest width, 1*25 ; wings when 
closed reached to within 1*5 of end of tail. Bill at front, 
0-7. [G. H.]
