202 A LIST OF THE BIRDS OF PEGU. 
Pegu and Rangoon. I have not seen it at any other time of 
the year. 
It is generally considered that the birds with white on the 
breast and abdomen are young, and that the black birds are 
adult. Is this proved? Dr. Dohrn (P. Z.8., 1866, p. 327) 
says of D. modestus: “The older they grow the more the 
tips of the feathers of the abdomen and breast are white 
bordered.” 
166.—Buchanga longicaudata, 4. Hay. 
This ashy black Drongo, exactly of the same tint of colour 
as the Malabar bird, appears to differ in the extent to which 
the tail is forked—a very important point in this family. I 
have only one Indian specimen, and the fork is 2-2 deep. In 
Burmese birds it varies from 15 to 17. The colour of this 
bird must prevent it ever being confused with the two next 
which are clear ashy and not ashy black. 
The present species is a constant resident, and fairly common 
in all forest country in Lower Pegu. 
167.—Buchanga intermedia,* Bly. (280 dzs.) 
The ashy Drongo, a totally different coloured bird from the 
preceding, is common throughout the province in wooded 
Jocalities. Wings, 4°9 to 5:4; tails, 56 to 6-05; fork of tail, 
1:7 to 1-9. ; 
168.—Buchanga pyrrhops, Hodgs. (280 dvs.) 
A larger form of the preceding with wing 5°75 ; fork of tail, 
2:0. I have no specimen of it, but Lord ‘'weeddale examined 
specimens collected at Rangoon by Captain Ramsay. 
169.—Chaptia enea, Vieill. (282.) 
Sparingly distributed over the whole province. 
170.—Bhringa remifer, Tem. (283.) 
Generally found, but rather rare. 
* This and the next are certainly not separable ; every intermediate size occurs, 
It is simply absurd to pick out all the large birds and call them one species, and 
all the small ones and call them another. 
Then as to difference of colour: it is most decided at the two ends of the scale, but 
we have fully one hundred specimens lying between the extreme forms, and abso- 
lutely bridging over the difference. It may be convenient to retain one name to 
indicate this form lying between longicaudatus and leucophea, but it is absolutely 
illogical for any one who adopts atra as the title for all the black Kingcrows, to go 
and make two species here. Why atra includes at least five races, each much more 
distinct (I speak of typical examples of each) than is pyrrhops from inter- 
media.—¥p., 8. F 
+ And Armstrong procured numbers there and elsewhere along the Pegu 
coast, and we have specimens from the Bassein river estuary.—Ep., 8. P’.
