EURYSTOMUS. 301 
“The size of all is about the same, the total length being about 229 to 
254; wing, 135; tail, 132; tarsus, 14; culmen, 20; width of gape, 33 to 35. 
“The specimens described above are all from Borneo. ‘Two females 
in the British Museum from Sumatra, in reddish plumage, are lighter 
than those from Borneo, being rather of a cinnamon-rufous color. The 
patches on the lower throat are cream-colored, with a cinnamon-rufous 
border and a blackish subterminal bar, but without any further blackish 
bars. 
“These differences, however, seem to me not constant after comparing 
the material in the Leyden Museum; nevertheless, I have not yet heard 
of any blackish specimens from Sumatra, and it must therefore be left 
open to question at present whether it is possible to separate the Sumatran 
and Bornean specimens specifically or subspecifically.” (Hartert.)
