This species [with the exception of C. gigas, Hartert and 

 Butler, which isonl) known from two specimens, thetypefrom 

 the Semangko Pass and another from Java (wing 157 mm.)], 



is tin' largest <>! the local species. The two specimens listed 

 above have wings of 129 and 131 mm. It is common on the 

 mountains from Larut in Perak to Selangor and has also been 

 obtained on the coast of Selangor at Tanjong Karang.

 "his. and bill black, feet dark purplish Hesh, toes 

 black." 



This species was exceedingly common on the cliffs of Koh 

 Mnk, where it built its untidy nests made of feathers ami K'ass 

 stems in the cracks of overhanging rocks at varying heights 

 above the sea while the Collocalia built far inside the caves in 

 total darkness. 



While dealing with this genus it may be mentioned that 

 the male of Cypselus pacificus obtained on Kedah Peal; in 

 December, 1915 (antea vol. vi, p. 226) agrees in all its charact- 

 ers with the subspecies C. pacificus cooki, described by Major 

 Haringtont from Goteik, Northern Shan States, where it was 

 found breeding. 



Our bird has the wing 1(13 and outer tail feathers 83 

 against 170 and 75 111 the type, the white rump band very 

 narrow with black shaft stripes and the white of the throat 

 much restricted with marked shaft stripes, the mantle deep 

 glossy black. These characters however occur also, though 

 to a lesser degree, in a bird from the Semangko Pass shot 

 in February, 1908. 



It appears to me not improbable that Harington has com- 

 pared a verv adult bird in fresh pelage 'his specimen was 

 breeding) with younger birds. The size is not materially more 

 than that of Malayan specimens, which vary from 163-176, 

 while Hartert (loc. citi Rives 176-184. 5 for the wing of the 

 species as a whole. 



Specimens from Koh Pennan, shot in May, are much 

 browner and duller.
