BIRDS OF TEKASSEEIM. 61 



of an evening, they always come from the direction of the 

 mountains, numbers following exactly in the trail of those 

 that had gone before, and all going back exactly the same 

 way at dawn the next morning"*. This I have not only noticed 

 to be the case with L. cerviniceps, but also with the smaller 

 L. lemminckii of the Malay Peninsula. 



The note of the present species is, as I mentioned before, a 

 full clear whistle which cau be heard a very long distance off; 

 it might be syllabized two-wee-oo, each syllable lengthened 

 out, but specially so the middle one. Occasionally the first 

 syllable is double and shortened too-too-wee-oo ; this whistle 

 the bird repeats at irregular intervals, one calling and another 

 answering. 



Unlike the ordinary Night Jars, they appear to settle but 

 seldom. I have never seen them settle on the ground, but on 

 one occasion, and on one occasion only, while lying at anchor 

 close to the bank in the creek at Choungthanoung, a Lyncornis 

 settled on an old stump within twenty yards of the boat, where it 

 remained some six or eight minutes, uttering at short intervals 

 its fine whistle ; it was a clear moonlight night, and I could 

 see it distinctly, and I noticed that, when about to whistle, its 

 head shot forward with a jerk. Its position when seated was 

 the same as that of Caprimulgus, squatting, with the lower breast 

 and abdomen resting on the thing on which it was seated. 



In the majority of the specimens I obtained (thirty-four), the 

 whole of the abdomen down to the vent was covered with a thick 

 layer of white fat, half an inch thick in some cases, lying 

 between the skin and the muscular tissue, but which separated 

 without difficulty from the skin. 



The food, of course, consists entirely of insects, which are 

 taken on the wing. 



This species' extends as far south, certainly, as Tonka in the 

 Malayan Peninsular, but how much further south it goes, and 

 where it meets with L. temminckii, I am unable to say. — W. D.] 



The following are the dimensions of numerous specimens 

 measured in the flesh : — 



Hales. — Length, 14'9 to 16-5 ; expanse, 34 to 37*25 ; tail, 8 

 to 9; wing, 11 -4 to 12-5 ; tarsus, - 7 to0"9 ; bill from gape, 1*62 

 to 1*9 ; weight, 8 ozs. 



Females. — Length, 15-12 to 165 ; expanse, 345 to 36 - 25 ; 

 tail, 7-9 to 9-0; wing, 11-37 to 12-62 ; tarsus, 0-75 toO'82 ; bill 

 from gape, 1-7 to 2-0 ; weight, 8 ozs. 



The legs and feet varied ; some were brownish pink, some 

 dull purpish brown, some light plumbeous brown ; the irides 

 were dark brown. 



* It is just possible, though by no means probable, that like some near allies the 

 Lyncornis may roost in caves in the hills. — A. O. H.
