Mr. Maitland-Heriot has sent me three adult and one young 

 specimen of H. hyperytJirus 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.fuyax, Horsf. (/. c), inasmucli as many of the 

 specimens attributed to the latter species in ]\Ialacca and 

 Borneo, and perhaps Java, whence the type of H. fugax came, 

 are really the young of H. hijperythrus , 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 sj^ecies 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 tins 

 species Hierococcyx bocki, sp, n. It is not H. msoides, Bl.,
