224 PIRDS OF THE 



This species is the Boruean representative of M. fiavi- 

 ventris from the Continent, from which species it differs 

 by its smaller size and the want of black on chin and throat.

Adult male and female from Mount Liang Koeboeng, 

 where the species is found in the undergrowth of the high 

 forest; also from Long Bloe. — Iris dark brown or gray, 

 bill black, feet pale blue, soles ochre. — The above-men- 

 tioned two birds are similar in every respect to four spe- 

 cimens of R. cyaniventris from Sumatra and one from Ma- 

 lacca in the Leyden Museum, so that I am absolutely 

 unable to find distinguishing characters. Those mentioned 

 by Sharpe in his above-quoted Catalogue do not hold at 

 all in the specimens which I have before me. The larger 

 size of the Bornean specimens is mentioned by Sharpe as 

 the strongest argument for a specifical separation, but the 

 following measurements will show that this argument does 

 not hold with the specimens in the Leyden Museum. 



Wing. Tail. 



Borneo {Jt. paroticalis) 2,7 — 2,8 inches; 2,0 

 Sumatra [R. cyaniventris) 2,8 — 2,9 » ; 2,2 — 2,5 ; 

 Malacca ( * » ) 3,05 ; 2,4 



Hab. Tenasserim, Malay Peninsula, Sumatra and Borneo, 

 where it was hitherto only recorded from Sarawak.
