BIKDS OF TENASSERIM. 45 



89.— Cotyle sinensis, Gray. (2). 



(Tonffhoo, Earns.) Pahpoon. 



Confined, to the northern portions of the province. 



[Rare in Tenasserim. I never saw it in the Gyne, Hong- 

 thraw, Attaran, or any of the more southern streams ; in fact 

 I only observed it at Pahpoon, where they occurred in mode- 

 rate numbers. When I was leaving Pahpoon about the end 

 of February these birds were just commencing to excavate 

 their nest-holes in the banks of the Younzaleen. — W. D.] 



Tenasserim specimens are, as pointed out, in the case of 

 others from Thayetmyo, S. F., III., 42, slightly different from 

 Indian ones ; but, after examining good specimens, I am quite 

 convinced that they are not sufficiently so to warrant specific 

 separation, and I withdraw the name obscurior that I proposed 

 for them if they proved really distinct. 



90 bis % — Ptyonoprogne ? 



Davison observed, about the inaccessible precipices on the 

 eastern side of Mooleyit, near its summit, numerous specimens 

 of a Ptyonoprogne, similar to, but smaller and much darker 

 colored than, rupestris, which he knows well, as it is common 

 about our own hill at Simla during October. He thinks it 

 was exactly like concolor, but that is scarcely likely to have 

 occurred there. Some such species, however, does occur about 

 Mooleyit ; he is perfectly certain of the flight, shape of wings, 

 &c, and few people have shot as many or know as well the 

 flight and shape of the Collocalias, Swifts, and Swallows of our 

 part the world. 



92. — Chelidon urbica, Lin. 



Col. Tickell says that this species occurs in great numbers 

 at Moulmein. In the B. of B. we are referred to J. A. S. B., 

 XXIV, 809, for this remark of Col. Tickell's. It may save trou- 

 ble to note that it really occurs, p. 227, n. 



95 bis. — Chsetura coracina, Mull. (4). 



Choungfchanoung; Pakchaii. 



Confined to the extreme southern portions of the province. 



[I first met with this pretty little Spine Tail at Choungtha- 

 noung, where a few were flying about over the tin mines ; further 

 south I met with it on several occasions. Going up the Pak- 

 chan in a canoe I saw numbers hawking over the water in com- 

 pany with C. iridic a, Cypselusinfumatus, &c, but shooting them 

 out of a shaky canoe was out of the question. In habits they 

 much resemble the greater Spine Tails, shooting down with the
