species with H. striolatus (Bp.), the types of which are in 
the Leyden Museum. Both Ramsay and Salvadori stated 
that their specimens from Western Sumatra differ from the 
Malaccan and Bornean birds in the following essential points: 
Upper surface olive-brown instead of olive-green, and the 
white-striped throat, chest and upper breast olive-green 
like in H. virescens instead of ashy olive. I regret to say 
that, after having looked over our material again and com- 
pared it with my Bornean specimens, I am unable to alter 
my former opinion (N. L. M. 1887, p. 63) as to the spe- 
cimens from Sumatra in the Leyden Museum. Our types 
of Trichophorus striolatus as well as the specimens collected 
by Dr. Klaesi in the Highlands of Padang have throat, 
chest and upper breast ashy gray with an olive tinge, 
while, according to Ramsay and Salvadori, they ought to 
be olive-green. As to the color of the upper surface, I 
must say that in our stuffed typical specimens it yields 
somewhat to olive-brown, but this very slight difference 
is probably due to their having been exposed to the light 
for more than fifty years in our galleries, Dr. Klaesi’s birds 
are olive-green above like those I have obtained in Borneo, 
Strange enough Nicholson, who described the birds col- 
lected in Sumatra by Mr. H. O. Forbes (Ibis 1883, p. 246), 
says that the Sumatran birds have throat and breast streaked 
with white as in H. malaccensis, but that the edgings of 
the feathers are olive-brown instead of greenish, and that 
the head is brown, characters which neither agree with those 
given by Ramsay and Salvadori, nor with H. malaccensis 
which has a green head and ashy gray edgings to the 
breast-feathers. 
The birds described by Ramsay and Salvadori are col- 
lected on Mount Singalang at a height of about 1600 m., 
and near the Lake Toba about 1500 m. above the sea. 
Having never seen one of those green-breasted specimens 
from Sumatra, I cannot tell much about their identity with 
H. malaccensis, but all our Sumatran specimens in the 
Leyden Museum, with the inclusion of the types of 7ri-
