ART. 12 BIRDS FROM ISLANDS NEAR BORNEO RILEY 21 



or no iridescent lilac purple. On the mainland the majority of the 

 males have these parts with much iridescent lilac purple, but some 

 have these parts green with little or no lilac. The most brilliantly 

 green-rumped, specimens examined are a male from West Sumatra 

 and one from Java. Stuart Baker ^^ restricts the type locality of 

 Nectarinia calcostetha Jardine to Borneo. 



38. AETHOPYGA SIPARAJA OCHROPYRRHA Oberholser 



Aethopyga siparaja ockropyrrha Oberholser, Bull. U. S. Nat. Mus., No. 98, 1917, 

 p. 65 (Pulo Rittan, Anamba Islands). 



One adult male and one immature male (marked female), Pulo 

 Raboe Raboe, May 4 and 6. 



The adult male agrees fairly well with a series, consisting of four 

 males, from the opposite shores of the main island of Borneo; it is 

 a little more yellowish citrine on the belly, the edges of the remigcb 

 are amber brown rather than raw sienna and the reds a little darker. 

 The series from the main island of Borneo is very close to males from 

 the Karimata Islands that have been assigned by Doctor Oberholser ^* 

 to the Anamba Island form ; the reds in the Karimata specimens are 

 just a trifle darker than in the Bornean males. The Raboe Raboe 

 male is like the Karimata bird in the tone of the reds, but it is more 

 yellowish citrine on the belly and the edges of the remiges are deeper 

 in color. The four males from Borneo measure : Wing, 49-51 (49.6) ; 

 culmen, 15-15.5 (15.2). The Raboe Raboe male: Wing, 50; culmen, 

 16. Two males from the Karimata Islands: Wing, 51.5-54; culmen, 

 16-16. 



39. LEPTOCOIVIA SPERATA (Linnaeus) 



Certhla sperata Linnaeus, Syst. Nat., ed. 12, 1766, p. 186 (Philippines). 



Three males, Pulo Maratua, May 13-21. 



These three males are very close to specimens from the Philippines ; 

 they seem to have a little smaller wing and bill and the belly is not 

 quite so yellow. The three measure: Wing, 47.5-48.5 (48) ; culmen, 

 13.5-14.5 (14). Ten adult males selected at random from a series 

 from the Philippines measure: Wing 49-52 (50); culmen, 14-15.5 

 (15).
