The genus Myiophonus has been split up into two subgenera, 
Myiophonus and Arrenga , the former comprising the species 
with lanceolate feathers, spotted as with dried gum, and having 
white spots on the wing-coverts, and the latter those with 
rounded feathers and bright-blue wing-coverts. The former 
section at present contains three closely allied species representing 
each other in their respective localities, viz.— 
1. M. temminckii, Vigors (Gould's ‘ Century/ pi. 21), with 
moderate, yellow bill. Hah. Himalayan range, as far as the 
Tenasserim provinces.
