150 ADDITIONAL NOTES ON THE BIRDS OF TENASSERIM 



t{ I myself am disposed to suspect that your bird and TickelFs 

 may represent a distinct species. Closely allied no doubt to affinis, 

 but with a considerably larger bill than the true affinis, and 

 differing moreover somewhat in shade of plumage and in 

 having more or less traces of a nuchal collar ; but until we ob- 

 tain some really good specimens it would be unwise to propose 

 any new name for the Burmese race.' 34 ' 



" Note : that the present specimen has just a perceptible 

 trace of the white nuchal collar, absolutely no white spots 

 whatever on the wing, but a few of the outer scapulars (all that 

 remain) broadly tipped with white, and margined with black." 



110.— Oaprimulgus macrourus, Horsf. 



This is the commonest Nightjar, and as Mr. Davison 

 remarks (S. F., Yol. VI., p. 58) its incessant call of tok-tok-tok 

 is very annoying at night. 



It is common in the Thoungyeen valley even in dense ever- 

 green forest. On the 15th March 1879, while tramping back 

 to my camp pitched on the bank of the Queebawchoung, a 

 tributary of the Meplay, I arrived about dusk at a dense bam- 

 boo forest just above my tent. There being lots of fallen 

 bamboos, I had to pick my steps carefully in threading my 

 way through, and in so doing all but trod on a female of the 

 above species ; she flew up, and 1 saw lying on the dry bamboo 

 leaves, a couple of blunt oval eggs, pinkish stone color, with 

 washed out purple blotches, clouds, and spots of various shades. 



Both these I found slightly set, and a third one half formed 

 in the oviduct of the female which I shot. I mention this 

 circumstance as I have never found more than two eggs in 

 any Nightjar's nest. 



Subsequently on the 15th March 1880, I found a second nest 

 with two eggs precisely similar, which measured 1*16 by 0'85 

 and 1-23 by 0*87. 



112. — Caprimulgus asiaticus, Lath. 



Dr. Armstrong procured a specimen of this species at 

 Amherst (S. F., Vol. VL, p. 59.) 



black and obscurely vermiculated ; all under parts from bill vinous rusty, with a 

 group of white ; black-margined patches on throat, and another across bottom 

 of breast, below which the colour is paler, and broken with rusty and dusky 

 irregular bars : this entends to lower tail-coverts ; lower back and upper tail-coverts 

 as back ; a pale tawny supercilium ; lining of wings whitish ; length, 9 inches ; 

 wing, 4f ; tail, 4f , of which beyond body 2| ; bill, f ; tarsus, J> B ; middle toe, f . 



* Since writing the above Mr. Hume and I have gone carefully through a series of 

 ascertained stellatus and affinis from the Malay Peninsula, and have little doubt 

 that this specimen is referable to affinis, which latter seems always tc want the white 

 spottings on the wing-coverts, while it has large white spots on the lower breast and 

 upper abdomen, which spots are more or less conspicuously edged with black. More- 

 over it has scarcely any trace of the nuchal collar on the back. The bird itself (to 

 judge from skins) and its bill are much smaller in the case of affinis.- -C. T. B.
