Mr. Maitland-Heriot has sent me three adult and one young 
specimen of H. hyperythrus from Manilla, and as I have 
compared these with the type and with a large series of allied 
species in the British Museum, the Tweeddale and Hume 
collections, and also in that of Mr. Seebohm, I am now of 
opinion that Count Salvadori was partly right in uniting this 
species to H.fugax , Horsf. (/. c.) } inasmuch as many of the 
specimens attributed to the latter species in Malacca and 
Borneo, and perhaps Java, whence the type of H.fugax came, 
are really the young of H. hyperythrus , Gld. The range 
of H. hyperythrus is Japan, Amoorland, China, and the Phi¬ 
lippine Islands, the young birds being found in Borneo and 
Malacca, and perhaps Sumatra and Java in the winter. It 
closely resembles H. nisicolor, Hodgs., which ranges from the 
Himalayas to Tenasserim, descending perhaps into the Malay 
peninsula, whence it has been recorded. 
For some years I have possessed a specimen of a Cuckoo, 
somewhat like H. sparverioides, collected in the mountains 
of W. Sumatra by Mr. Carl Bock. As all the specimens that 
I have ever seen of H. fugax , Horsf., were in the striated 
plumage common to young Cuckoos, it occurred to me that 
perhaps my bird was the adult of that species; but I am now 
convinced that it is not so, but an undescribed species dif¬ 
fering from H. sparverioides in being much smaller (wing 7*5) 
and in being of a much darker and richer brown above; the 
entire head and throat, moreover, is ashy grey, very different 
from the dark ashy beard of that species. I propose to call this 
species Hierococcyx bocki, sp. n. It is not H. nisoides > Bl.,
