. 24. GERYGONE SALVADORII Biittikofer 



Oerygone salvadorii Buttikofer, Notes from the Leyden Mus., vol. 15, 1893,, 

 p. 175 (southern Borneo). 



One male and one female, Pulo Raboe Raboe, May 4 and July 27 ; 

 two males and one female Pulo Samama, April 22. 



No additional specimens from Borneo of this rare form are avail- 

 able for comparison, but they seem to agree with the original de- 

 scription and the measurements are about the same as given there. 

 The white spot on the inner web of the outer tail feathers near the 

 tip is well marked on the three outer and occurs on the fourth as a 

 mere dot. 



25. HYPOTHYMIS AERLA. Bangs and Peters 



Hppothymis aeria Bangs and Peters, Occasional Papers of the Boston Soc. 

 Nat. Hist, vol. 5, 1927, p. 237 (Maratua). 



Seven adult males, one immature male, and four adult females, 

 Pulo Maratua, May 9-20. 



Three males and two females of the above series come from the 

 small islets of Alanga and Sangalan in the bay at the north end of 

 Maratua. 



This very distinct species needs no comparison. Judging from 

 descriptions, it seems to be an approach towards Hypothymis rowleyiy 

 which is not available for comparison. In two of the above males 

 of H. aeria^ the black jugular collar is very faint, practically absent ; 

 and in the majority of the males the occiput is darker than the crown^ 

 but not black. 



26. HYPOTHYMIS AZUREA PROPHATA Oberholser 



Hypothymis azurea prophata Oberholser, Proc. U. S. Nat. Mus., vol. 39, 1911, 

 p. 597 (Great Karimon Island). 



One female, Pulo Miang Besar, September 10. 



This specimen is lighter on the back and head and the tail is more 

 tinged with bluish than in a female from Banka. The Miang Besar 

 specimen measures : Wing, 67.5 ; tail, 66 ; culmen, 13. 



27. RHn»IDURA JAVANICA JAVANICA (Sparrman) 



Muscicapa javanica Sparrman, Mus. Carls., fasc. 3, 1788, pi. 75 (Java). 



One male, Pulo Raboe Raboe, May 4; two males and one female, 

 Pulo Derawan, July 23-25 ; one female, Pulo Eraban, June 13.
