Representative forms of the same character as those noted above are found
in all extensive continental areas, but they are rarely so numerous. Thus,
in Mr. Elwes' paper on the "Distribution of Asiatic Birds," he states that
12.5 per cent. of the land birds of Burmah and Tenasserim are peculiar
species, whereas we find that in Borneo they are about 25 per cent., and
the difference may fairly be imputed to the greater proportion of slightly
modified representative species due to a period of complete isolation. Of
peculiar genera, the Indo-Chinese Peninsula has one--Ampeliceps, a
remarkable yellow-crowned starling, with bare pink-coloured orbits; while
two others, Temnurus and Crypsirhina--singular birds allied to the
jays--are found in no other part of the Asiatic continent though they occur
in some of the Malay Islands. Borneo has seven peculiar genera of
passeres,[89] as well as Haematortyx, a crested partridge; and Lobiophasis,
a pheasant hardly distinct from Euplocamus; while two others, Pityriasis,
an extraordinary bare-headed bird between a jay and a shrike, and
Carpococcy
