134 CONTRIBUTIONS TO THE ORNITHOLOGY OF INDIA. 



Here again the division is far from exact. D. leucophams runs 

 high up into Burmah, C. xanthorhynchus has occurred in Tenas- 

 serim, L. lucionensis and G. melanolophus have been obtained 

 in Ceylon, and 0. anostJicetus and P. fiavirostris are perhaps 

 more essentially African than Archipelagian or Australian. 



So far then as the species not peculiar to the islands are 

 concerned, the influence of the Indian sub-region has vastly 

 predominated. The whole of the 31 western species are common 

 to this region, so that to it in round numbers may be attributed 

 two-thirds of the whole number, while the Indo-Burmese and 

 Australian and Archipelagian regions have between them only 

 contributed about one-third, the latter furnishing considerablj 

 the larger quota. 



If now we look to genera the preponderance is still more 

 marked. Out of a total of nearly 120, only five Non-Indian, 

 Indo-Malayan, Archipelagian or Australian genera are repre- 

 sented, viz : — 



Lyncornis, 



Lalage, 



Caloenas, 



Megapodius, 



Eudroraias, 



Goisakius, 

 of -which the second, third, fourth, and sixth are virtually con- 

 fined to the Nicobars, though stragglers of the third and fourth have 

 occurred at the Andamans and Qpcos, and of the sixth in Ceylon. 

 Au reste five others are, within our limits, represented only 

 in the Indo-BuVmese sub-region, viz : — 



Rhyticeros, 



Hylocharis, 



Calornis, 



Macropygia, 



Euryzona, 

 but the remainder, more than nine-tenths of the whole, (although 

 some of them, e.g.,-**- 



' Spizaetus, 



Spilornis, 



Collocalia, 



Euiystomus, 



Pelargopsis, 



Loriculus, 



Artamus, 



Centrococcyx, &c, 

 may be more fully represented elsewhere,) pertain clearly, though 

 by no means exclusively, to the Indian sub-region, as it now is.
