44 BIRDS OF TENASSERIM. 



85 ? — Hirundo striolata, Tern. 



Lord Tweeddale says (B. of B., p. 127.) : " Karennee at 2,600 

 feet, in March; Karen Hills, at 3,000 feet, in January — 

 Wardlaw Ramsay. Identical with Flores, Formosan, and 

 Chinese examples. Quite distinct from C. erythropygia, which 

 is barely separable from C. rufula." 



I look upon the occurrence of true striolata in Tenasserim 

 with much doubt. The birds referred to more probably belong 

 to nipalensis or sub-striolata, S. F., V, 264. No one who has 

 at all studied this group could talk of erythropygia as barely 

 separable from rufula ! The distinctions are poiuted out 

 S. F., V., 265, etante. 



85 Us.— Hirundo nipalensis, Modgs. (9). Descr. 

 S. P., V., 262. 



Pahpoon ; Pakchan ; Bankasoon ; Malewoon. 



Sparingly distributed in suitable localities throughout the 

 province. 



[I only saw these Swallows in the extreme north and south 

 of the province. They affect open grassy slopes, and these 

 are not common elsewhere. — W. T>.~\ 



I have already, loc. cit. sup., dealt fully with the sub-group of 

 Swallows to which this species belongs. The birds here 

 entered are of course the daurica of my first list. Moreover, 

 the birds formerly entered in my second list, as erythropygia, 

 proved on careful comparison to be nipalensis also. 



87— Cotyle riparia, Lin. (11). S. F., 1,164; III., 



452, IV., 507. 



Khyketo ; Kedai-Keglay ; Theinzeik ; Thafcone. 



Confined apparently and as a seasonal visitant to the tracts 

 between the Salween and Sittang. 



[The European Sand Martin was common late in January 

 and early in February over the whole of the level country 

 lying in the Thatone sub-district, but I have not as yet seen 

 it elsewhere in Tenasserim. — W. D.]
