107. ChaPTIA SIALATE^-SIS. 



Chaptia vialaycnsis, A. Hay, J. A. S. B. 1846, p. 294, " Malacca ; " Walden, J. A. S. B. 

 1875, extra number, pt. ii. p. 128. 



Edolius picinus, S. Muller, Bp. Consp. i. p. 352, "Sumatra" (1854). 



Malaccan and Sumatran individuals do not differ. 



108. BUCHANGA LEUCOPHJEA. 



Dicrurvs leucophmis, Vieillot, N. Diet. d'Hist. Nat. ix. p. 587 (1817). 

 Edolius cineraceus, Horsf. t. c. p. 145, "Java" (1820). 



Javan and Sumatran examples are identical. 



109. Peeiceocotus aedens. 



Turdus fiammeus (Gm.), Eaffles, t. c. p. 310, " Sumatra." 



Phoenicornis ardens, "Boie," Mus. Lugd. ; Bp. Consp. i. p. 357, " Sumatra" (1850); Salvad. 

 t. c. p. 143, t. ii. f. 1, 2. 



Pericrocotusflammifer, Hume, Str. F. iii. p. 321, note, " Mergui " (1875). 



Bornean and Malaccan examples agree with typical. Horsfield and Moore (Cat. E.I. C. 

 Mus. ii. p. 142) refer T.flammeus, apud Kaifles, and P. ardens to P. xanthogaster. 



110. Peeiceocotus peeegeinus. 



Parus peregrinus, Linn. S. N. i. p. 342 (1766). 



One specimen, seemingly belonging to this species, vpas obtained by Mr. Buxton ; but as it 

 is in immature plumage it is difficult to determine with certainty. 



111. Peeiceocotus xanthogastee. 



Lanius xanthog aster, RafHcs, t. c. p. 309, "Sumatra" (1821). 

 Ibis, 1877, The small section of the Pericrocotidm of which P fiammeus may be considered the type, is 



P- ^^^- represented both in Sumatra and Java by a race which it may perhaps be proper to separate as a 

 distinct species. Of this form two representatives are contained in Mr. Buxton's collection. It 

 is a smaller bird than P. fiammeus, and it differs in the orange edgings of the outer webs of 

 some of the secondaries uniting with the orange-coloured mark lower down, as is to be found 

 in P. hrevirostris. The female of this form appears to have supplied the type of Lanius xantho- 

 g aster. Raffles. 



112. Puile.xtoma pyeehopteeum. 



Muscicapa pyrrhoptera, Temm. PI. Col. t. 596, "Sumatra, Borneo" (1836). 

 Examples from Borneo and Malacca perfectly agree with the one obtained in the Lampong 

 district by Mr. Buxton.
