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 Boruean 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 

 B. malaccensis^ but all our Sumatran specimens in the 

 Leyden Museum, with the inclusion of the types of Tri-
