48 BIRDS OF TENASSERIM. 



101 bis.— Cypselus pacificus, Lath. (2). Descr. S. E., 

 III., 43. 



Amherst ; Bankasoon. 



Only observed in the southern half of the province. 



[I have noticed this Swift on several occasions at Amherst 

 and southwards, but it cannot be said to be common anywhere. 

 I only secured two specimens — one at Amherst and one at 

 Bankasoon. — W. D.] 



The following are the dimensions of a male and female re- 

 corded in the flesh : — 



Male. — Length, 7*5 ; expanse, 165 ; tail from vent, 3*15 

 wing, 6*8; tarsus, 0*4; bill from gape, 0*85; weight, 1 oz. 



Female. — Length, 7"25 ; expanse, 1575 ; tail from vent 

 312; wing", 65 ; tarsus, 0*5; bill from gape, 0*75; weight 

 1-75 oz. 



Legs and feet purplish black ; claws horny black ; bill black 

 irides deep brown. 



102. — Cypselus batassiensis, J. E. Gray. 



I gather from Mr. Blyth's remarks (B. of B., p. 84) that he 

 was of opinion that this species occurred in Tenasserim. I how- 

 ever doubt its occurrence. Mr. Davison tells me that near 

 Khyketo he saw a number of small Swifts flying in and out 

 and about the fronds of a set of palm trees. He made sure 

 that they were batassiensis, but on shooting specimens they 

 proved to be infumatus. Other people shooting this latter, 

 before infumatus became generally known, may probably have 

 reported the occurrence of batassiensis, but there is no reason 

 to believe that this does really ever visit Tenasserim. 



102 Us.— Cypselus infumatus, Sclater, (16). Descr. 

 S. F., III., 44. 



{Tonghoo, Rams.) Pahpoon ; Khyketo; Amherst; Mergui ; Bahonee ; Pak- 

 chan ; Malewoon. 



Common throughout the plains portion of the province, 

 but especially abundant in the south. 



[At Amherst all round the circuit bungalow, at Mergui on 

 the five pagoda plains, on the Thatone plains, in fact wherever 

 the ground was open, many of these birds might be seen hawk- 

 ing close over the ground. I have once seen them about the 

 fronds of a toddy palm. I do not know where they roost or 

 breed. They seemed to me to be permanent residents. —
