 134. HIRUNDO KUSTICA GUTTURALIS Scopoli. 



A fair series of both sexes and immature from : Toli Toli, Decem- 

 ber 12 and IT, 1914; Parigi, September 24-October 5, 1916; Dolo, 

 December 25 and 26, 1916 ; Rano Lindoe, March 10-27, 1917 : Napoe, 

 Watoetaoe, November 20, 1917. 



135. HYPUROLEPIS JAVANICA FRONTALIS (Qnoy and Gaimard). 



A fair series from the following localities: Toli Toli, November 

 28, 1914; Koeala Prang, June 17 and 18, 1916; Parigi, September 

 28, 1916; Toboli, October 17 and 21, 1916; Manilili, December 16, 

 1916. 



This series averages darker on the forehead and throat than Javan 

 birds, but the breast and belly appear lighter; there is little or no 

 difference in size. Birds from the Philippines, Borneo, the coast 

 of the Malay Peninsula, the Anambas, and the Mergui Archipelago 

 appear to be much like those from Celebes in color, allowing for 

 individual variation, but have a longer wing, and belong to the form 

 named by Oberholser ^^ Hypurolepis javanica abhotti^ with the range 

 expanded. It is true the type of the latter has the throat a little 

 darker and of a somewhat different shade than any in the series from 

 the Philippines or elsewhere but the difference is slight and besides 

 it is in freshly acquired plumage, before fading has set in; a speci- 

 men from Borneo (No. 178118) closely approaches it. I have no 

 specimens from the type locality of H. j. frontalis for comparison 

 but as the Celebes bird apparently does not belong to the Javan race 

 or the one to the north there is nothing left to do but follow prece- 

 dent ^^ in the matter and refer it to the southern race for the present. 

 Of Hypurolepis javanica domicola of peninsular India, I am not 

 able to speak, having no specimens.
