THE ISLANDS OF THE BAY OF BENGAL. 129 



Palaeomis caniceps, Blyth, (p. 178.) 

 Palasornis eiwthrogenys, Blyth, (p. 181.) 

 iEthopyga nicobarica, Hume, (p. 196.) 

 Hypsipetes nicobariensis, Moore, (p. 223.) 

 Oriolus macrourus, Blyth, (p. 228.) 

 Temenuchus erythropygius, Blyth, (p. 247.) 

 Carpophaga insularis, Blyth, (p. 262.) 

 Megnpodius nicobariensis, Blyth, (p. 276.) 

 One species is peculiar to the Cocos — 



283 bis. Dissemuroides dicruriformis, Hume, (p. 211.) 

 and one to Narcondam — 



146 quat. Rhyticeros narcondami, Hume, (p. 176.) 

 I am quite aware that several of these will not be univer- 

 sally admitted as good species, and also that it is highly probable 

 that when Sumatra and Tenasserim (which latter I am working 

 now) have been more fully explored, some of the species 

 now believed to be peculiar to the islands will prove to have 

 a more extended range. Still this will not materially affect the 

 point that I am now pressing, viz., the highly specialized 

 character of the ornis, the more so that there are probably 

 still peculiar species to be discovered in the Great Nicobar, 

 and that many of the local races which I have now to enumerate, 

 will, by many ornithologists, be considered entitled to specific 

 separation. These races are — 

 peculiar to the Andamans — 



129. Halcyon smyrnensis, Lin., (p. 167.) 



475. Copsychus saularis, Lin., (p. 230.) 



797. Turtur humilis, Temm., (p. 269.) 



913. Hypotsenidia striata, Lin., (p. 302.) 



peculiar to the Nicobars — 



127 ter. Pelargopsis leucocephala, Lin., (p. 166.) 

 290. Myiagra azurea, Bodd, (p. 217-) 



common to both groups — 



134. Alcedo bengalensis, Gmel., (p. 173.) 



285 ter. Dissemuras affinis, Tytler, (p. 212.) 

 631 ter. Zosterops nicobariensis, Blyth, (p. 242.) 

 693. Eulabes javanensis, Osbeck, (p. 254.) 



701. Muriia striata, Lin., (p. 257.) 



834. Turnix joudera, Hodgs., (p. 281.) 



-What is even more noteworthy than the specialized charac- 

 ter of the ornis of these islands as a whole, is the remarkable 

 extent to which it is localized in the several groups. A. glance 

 at the . map will show that (setting aside Barren Island and 

 Narcondam, which pertain to an outlying line of disturbance)
