The nearest ally of this species appears to be Turdus xan- 

 thorhynchus Salvad., from Prince's Island. 



This Thrush is by no means common, being confined to 

 the eastern and southern portions of the island, where it 

 frequents the wooded highlands.

Total length 5 - 2 inches, culmen 0'55, wing 26, tail 2 - 25, 

 tarsus 0*9. 



The sexes are similar in plumage and measurements. 



This Lioptilus frequents high altitudes, and was the last 

 species observed near the summit of St. Isabel. Though the 

 birds were often obscured from view by the heavy mountain 

 mist, their pretty flute-like songs could be heard from the 

 tops of the trees. We generally observed them in small 

 parties of four or five. 



The nearest ally of this species is L. abyssinicus, from 

 East Africa. 



Named after my brother Mr. Claud Alexander, 1st Scots 

 Guards.
