BIRDS OF UPPER PEGU. 45 



the Garrow and Naga Hills. It was originally obtained in 

 Borneo, and now we find it common here about Thayetmyo and 

 equally so further south in Tenasserim. 



This species is very similar to C. palmar um, Gray, so common 

 throughout India ; but it is everywhere much darker-colored, 

 has a considerably shorter tail (that of palmarum being about 

 2*7), arid is consequently shorter altogether, has a less-forked 

 tail, the external rectriees projecting only about 1*1 beyond 

 the central ones, instead of 1*3 to 1-4 as in palmarum, and 

 has generally a slightly shorter wing. In fine specimens the 

 wings, head, and tail are nearly black; the back, deep blackish 

 hair-brown ; the whole upper surface with a faint greenish gloss ; 

 the entire lower surface, a moderately dark sepia brown, slightly 

 albescent on the chin and throat. 



104.— Dendrochelidon coronatus, Tick. 



Mr. Oates remarks : " Common everywhere throughout the 

 year ; it is particularly fond of clearings in thick forests where 

 a lot of big trees have been killed by fire. At Palow bungalow 

 it is to be seen at all hours of the day flying over the house and 

 dipping with incredible velocity to the surface of the Irrawaddy, 

 which flows about eighty feet below the steep bank on which the 

 bungalow is built. A female measured — 



"Length, 9'05; expanse, 15'3; tail, from vent, 5*2; wing, 

 6-3; bill, from gape, 0'78 ■ tarsus, 0'28. 



" The bill was black ; eyelids, dusky plumbeous, blackish at the 

 edges; iris, dark brown; legs, pinkish brown; claws, black." 



109.— Caprimulgus albonotatus, Tick. 



A male and female belonging rather to this species than the 

 next, with the wing of the male measuring 8*3, and agreeing 

 precisely in tint with birds from Central and Northern India, 

 have been sent by Mr. Oates, who says that this and the next 

 species which he did not discriminate are common on the Pegu 

 Hills, where it entirely replaces asiaticus. He gives the dimen- 

 sions of a male — 



" Length, 12*7 ; expanse, 24 ; tail, from vent, 6*7 ; wing, 

 8*4 ; bill, from gape, 1*4 ; tarsus, 0*8. 



■■ Of this speciinen the bill was black ; the whole gape, vinaceous; 

 eyelids, dark plumbeous brown ; the edges, reddish ; legs and feet, 

 vinaceous brown ; claws, dark horny/'' 



I think that it is at any rate questionable how far it may 

 ultimately prove desirable to separate the present and the suc- 

 ceeding species. No doubt typical macrurus, with its very dark 

 tint, and wing in the adult male not exceeding 7*75, does appear 

 a very different bird to the huge pale albonotatus, with its 8*8
