132. TRERON N1PALENSIS. 
Columba curvirostra, Gm., Raffles, t. c. p. 318, “ Sumatra/* 
Toria nipalensis, Hodgs. As. Res. xix. p. 164, “Nipaul** 
(1836). 
Treron nasica, Schlegel, Nederl. Tijdschr. Dierk. i. p. 67, 
“Borneo** (1863). 
Assam, Sumatran, and Malaccan examples are identical. 
133. Butreron capellei. 
Columba capellei, Temm. PI. Col. 143. “Java** (1823). 
Vinago gigantea , Vigors, App. Mem. Raffles, p. 674, “ Su¬ 
matra (1830). 
Malaccan individuals do not differ. Raffles does not appear 
to have ever published the title of Columba gigantea attributed 
to him by Mr. G. R. Gray ( Columbce , B. Mus. p. 13). 
134. OSMOTERON VERNANS. 
Columba vernans, Linn. Mantissa, p. 526, “ Philippines ** 
(1771) ; Raffles, t. c. p. 318, “ Sumatra;** Walden, Tr. Z. S. 
ix. p. 210. 
Treron griseicapilla, Schlegel, Nederl. Tijdschr. Dierk. i. 
p. 70, “Sumatra, Bangka** (1863). 
Notwithstanding Professor Schlegel*s remarks (/. c.), I 
am unable to detect any specific difference between Su¬ 
matran and typical examples. 
135. OsMOTRERON OLAX. 
Columba olax, PI. Col. 241. “ Sumatra** (1823). 
Sumatra supplied the type of this species; and Malaccan 
examples in no way differ.
