Obs. The occurrence of this Grosbeak in the mountains 

 of Yemen is of great interest. R. socotranus is confined 

 to Socotra, R. percivali to the mountains of Hadramut, 

 S. Arabia, and R. louisae to the mountains of North 

 Somaliland. 



Dr. C. B. Ticehurst exhibited on behalf of Mr. W. Eagle 

 Clarke examples of the Hebridean Song-Thrush (Turdus 

 musicus hebridensis) , and made the following remarks : — 



" The native Song-Thrush of the Outer Hebrides has long 

 been known to differ by the darkness of its plumage from 

 Thrushes found elsewhere in Britain, and this was pointed 

 out by the late Mr. Robert Gray in his ' Birds of the West 

 of Scotland ' in 1868. This Thrush, however, was not 

 described in detail or named until Mr. Eagle Clarke did so 

 in 'The Scottish Naturalist/ 1913, pp. 53-55. Here he 

 pointed out that the mantle and wings are darker brown ; 

 the head slightly redder than in the British race, and the 

 under-surface has the black ovate spots larger, more numerous, 

 and of a more intense black, while the buff colour is paler. 

 The flanks are conspicuously streaked with greyish-brown 

 showing little buff, and the buff of the under wing is richer 

 and redder. 



"I would further point out that the juvenile plumage also 

 differs from that of the British race, in the same way as that 

 of the adult.* 



"The exact distribution of this race has not yet been 

 determined, but it is known to occur in Barra and South Uist. 

 There is evidence to show that a Song-Thrush was resident 

 in St. Kilda about 1840, but is not to be met with there 

 now. 



"Continental and British Song-Thrushes occur in the 

 Outer Hebrides on migration and in winter, and since the 

 planting of trees at Stornaway Castle the British Song- 

 Thrush has bred there."
