Borneo, its occurrence in Sumatra is nothing very remarkable. 

 Still it is a valuable addition to the Sumatran list, being the 

 only known Asiatic member of the family Indicator idae. 



I compared my specimen in the Leyden Museum with the 

 type of the species, which came from Borneo, and could not 

 find any difference. 

 Gyanoptila cumatiUs Thayer and Bangs. 



One adult male, from Kaban, 22nd of February, 1916. 

 This species was described by Thayer and Bangs (Bull. Mus. 

 Comp. Zool. Harward Coll. LII. 1908—1910, p. 141) from Ma- 

 Fu-Ling, Hupeh, Central China. It seems to be restricted to a 

 comparatively small area and its occurrence on migration in 

 Sumatra is important, as it m£,y throw light on the roads of 

 migration of Chinese birds. 



This species differs from G. hella in having the back verditer- 

 blue and the throat and breast of this same colour and not 

 black, lastnamed colour being confined to the chin. Young males 

 of G. hella have the same verditer-blue tinge on the back, but 

 they may be distinguished by their black throat and breast. 

 Turdinus lepidopleurus (Bp.). 



Turdinus macrodactylus (Strickl.) from Malacca and T. lepido- 

 pleurus (Bp.) from Java are certainly geographical forms of one 

 species. They differ chiefly in size, the Malaccan bird having a stouter 

 bill. I have compared my specimens from Sumatra with the type 

 and other Javanese specimens of T. lepidopleurus as well as with 

 specimens of T. macrodactylus in the Leyden Museum and was very 

 much surprised to find that they agreed with the former and not 

 with the latter. 



I give here the measurements of the three specimens in Dr. de 

 Bussy's collection, one female and two males, shot on the 26t^» of 

 June 1916 at Basilan: 



9: ala 90, cauda 58, tarsus 31, culmen 22 mm. 

 cf : ala 91,5, cauda 62, tarsus 32, culmen 21 mm. ■ 

 cf : ala 37, cauda 64, tarsus 33, culmen 20 mm.
