the white centers to the under tail coverts of the latter. Gofsychus 

 amoenus is very close to No. 3, but lacks the white under tail coverts 

 and the white mixture on the lower belly and flanks of the latter 

 and the tail pattern is different. 



Of Gopsychus amoenus the United States National Museum has 

 six males and five females from southeast and north central Borneo, 

 but of the other two only a pair of each. The male of Gopsychus 

 niger is from Sandakan and the female as listed above. The pair of 

 No. 3 are from Kina Balu. Gopsychus saularis musicus or a simi- 

 lar form also occurs in Borneo. It has the whole belly white. 



Stresemann-2 has attempted to explain the differences between 

 Gopsychus saularis musicus and Gopsychus amoenus on the grounds 

 of mutation, but not very successfully, it seems to me. He does not 

 mention Gopsychus niger in the article.
