that the birds from the southern part of the Indian peninsula will 

 ultimately prove different from those of the north, in which case the 

 Halcyon bruniceps of Jerdon a should be their name 



The measurements above given are from the following specimens: 



RAMPHALCYON CAPENSIS BURMANICA (Sharpe). 



Pelargopsis burmanica Sharpe, Proc. Zool, Soc. Lund., 1S70, p. G7 (Ton- 

 ghoo, Burma). 



Subspecific characters. — -Resembling Ramp halcyon capensis ca- 

 pensis, but much larger; pileum conspicuously capped with dull 

 brown, without admixture of ochraceous; back, wings, and tail 

 lighter and decidedly more greenish. 



Measurements. — Three male*: Wing, 143-154.5 (average, 149.7) ; 

 tail, 92.5-98 (average, 94.7) ; exposed culmen, 71-79.5 (average, 7G.5) ; 

 tarsus. 17-18 (average, 17.7). One male: Wing, 162; tail, — ; ex- 

 posed culmen, 77.5; tarsus. 19 mm. 



Type-locality. — Tonghoo, Burma. 



Geographical distribution. — Andaman Islands, Burma, and Tenas- 

 serim, east to Siam, Cambodia, and Cochin China. 



The present race may be distinguished at a glance from Ramphal- 

 cyon c. javana, R. c. gigantea, R. c. gouldi, and R. c. intermedia by its 

 very conspicuous brown cap, and from each of these by other charac- 

 ters as well. It has the pale and very greenish back, wings, and tail 

 of Ramphalcyon c. gouldi, but even more strongly developed. There 

 is considerable individual variation in Ramphalcyon c. burmanica, 

 particularly in the color of the pileum. Young or immature birds, 

 as in some of the other races, appear to be somewhat darker than 

 adults. Specimens from Siam seem to be rather larger than those 

 from Burma. Birds from the Andaman Islands are said to be still 

 paler than those from the mainland, and may ultimately be found to 

 represenl an unnamed race. 



The specimens supplying the above measurements arc as follows:
