230 BIRDS OF THE 
Borneo our collections contain two specimens of the true 
C. gutturalis from Sumatra, both collected by S. Mitller. 
As to C. sumatranus, our Museum is in possession of 
an adult male, collected by S. Miiller in Sumatra and 
strange enough, of another, also of an early date, said to 
come from Borneo. This latter fact is the more strange, 
as from Borneo was already known a second species of 
Criniger, C. ruficrissus, which would take a similar position 
in Borneo as C. sumatranus in Sumatra. It must be left 
to later investigations to make out whether C. swmatranus 
is really an inhabitant of Borneo as indicated by that single 
specimen in the Leyden Museum. 
Finsch (1. ¢.), in describing his C. gutturalis after the 
specimens in the Leyden Museum, used as objects the male 
of C. sumatranus and a female of C. gutturalis, as we 
learn from his remarks about the female.

Mos. VI, p. 81; id. Ibis 1889, p. 274; Everett, L. B. Born, p. 113. 
Six specimens from Mount Liang Koeboeng, where they 
are found in high forest. — Iris blood red, bill horny blue, 
feet flesh-color. 
This species is closely allied to C. gutturalis, from which 
it differs more strikingly than C. swmatranus especially in 
the following points: like in C. sumatranus the crown is 
olive-brown instead of rusty brown, the occipital crest more 
developed, the white feathers on chin and throat longer 
and purer white and the under tail-coverts darker brown. 
Moreover C. rujicrissus is somewhat larger and of a duller 
color above and below than both its above-mentioned 
congeners, being less lively olive-green but rather grayish 
1) The specimen (N° 653), ranged by Salvadori with some donbts to C. 
gutturalis, though it is larger and darker above and below, undoubtedly 
belongs to the present species.
