92 Mr. H. F. Witherby on Birds from 
describing S. rupicola, took a young bird for an old one. 
I obtained several young birds with their parents, and 
although these young birds appear to be fully developed 
yet their measurements are very small. The wing-feathers 
are fully grown, but measure only 72 mm. as against 
86-92 mm. in the adult, while the bill and legs are 
correspondingly small. Unhke most Passeres, therefore, it 
is evident that the Rock-Nuthatch’s first quill-feathers are 
remarkably small and are moulted with the rest of its 
juvenile plumage. 
Sitta syriaca obscura Sar. & Loud. (Orn. Monatsb. 1905, 
p. 76) seems referable to Silta neumayeri tephronota Sharpe 
(cf. Hartert, V6g. pal. F. p. 339), while the description of 
yet another race from the Caucasus region by Mr. Buturlin 
(‘ Ibis,’ 1906, p. 417) under the name of S. syriaca parva 
adds further to the confusion. This last will prove, I think, 
to be another synonym of S. n. tephronota. The rufous 
edgings to the tail-feathers vary considerably in different 
specimens. Mr. Buturlin does not exactly compare his new 
form with either S. ». newmayert or S. n. tephronota, but 
with Blanford’s description of S$. rupicola and M. Sarudny’s 
and Blanford’s descriptions of S. syriaca, all of which are 
mixed ! 
TROGLODYTES PARVULUS HyRcANUs Sar. et Loud., Orn. 
Monatsb. 1905, p. 106. 
Troglodytes parvulus Koch ; [B. 222]. 
6. July 25, Sumela, alt. 1500 ft. 
“A few seen.”—R. B. W. 
This specimen differs distinctly from typical 7°. parvuius 
in the pale, much less reddish colouring of its upper side 
and in the distinctness of the spotting on the belly. It is 
much like 7. pallida Hume, but differs in the dark bars 
on the feathers of the belly being black, not brown, and 
more distinct. The shoulder-feathers are also tipped with 
white, which does not appear to be the case in 7. p. pallidus. 
I have referred this specimen to 7. p. hyrcanus, but it does 
not altogether agree with the description given by Baron 
Loudon and M. Sarudny. It is, however, in such worn
