Lord Tweeddale on Birds from 
in the same area; and yet there seems no doubt that both 
inhabit Tenasserim; and an example of a young male ob¬ 
tained at Tonghoo by Mr. W. Ramsay belongs to B. undu- 
latus, while the remainder of a very large series from that 
district consist of nothing but B. subruficollis. There is 
little or no difference in the general dimensions, although Mr. 
Blyth considered that the body of B. undulatus was heavier 
than that of its ally. 
B. narcondami , Hume (Str. F. i. p. 411), as described, 
seems to be another closely allied form. No mention is 
made of lateral ridges on the mandibles. 
31. Carcineutes pulchellus. 
Dacelopulchella, Horsf. t.c. p. 175, “Java” (1820). 
Carcineutes pulchellus (Horsf.); Sharpe, Mon. Alced. t. 96. 
This bird is not separable from Malaccan and Peguan ex¬ 
amples. 
32. Halcyon pileata. 
Alcedo pileata, Bodd. Tab. PI. Enl. p. 41 (1783). 
Alcedo atricapilla, Gm.; Raffles, t. c. p. 293, “ Sumatra.” 
33. Sauropatis chloris. 
Alcedo chloris , Bodd. Tabl. PL Enl. p. 49 (1783). 
Alcedo chlorocephala, Gm., Raffles, t. c. p. 293, “Sumatra.” 
34. Pelargopsis fraseri, Sharpe, P. Z. S. 1870, p. 65, 
“Java, Sumatra, Malacca;” Mon. Alced. t. 33, “Sumatra.” 
Alcedo leucocephalus, Gm., Raffles, t. c. p. 293, “ Sumatra.” 
The four examples obtained by Mr. Buxton most closely 
resemble the Bornean form referred by Mr. Sharpe in his 
monograph to P. leucocephala, the cap, however, being more 
pronounced. They differ from the great majority of Malaccan 
individuals with which I have made a comparison in wanting 
the very dark distinct brown cap of that peninsular form. But, 
in truth, this group of Kingfishers requires further study; for 
the variations in colouring of the cap, on which Mr. Sharpe 
partly relies (P. Z. S. 1870, p. 62), do not always seem to offer, 
as I once believed, stable characters when a large series of 
individuals from different, or even similar, localities are 
examined.
