230 BIRnS OF THE 



Borneo our collections contain two specimens of the true 

 C. gutturalis from Sumatra, both collected by S. Muller. 



As to C, sumatramis, our Museum is in possession of 

 an adult male, collected by S. Muller 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. sumatranus 

 is really an inhabitant of Borneo as indicated by that single 

 specimen in the Leyden Museum. 



Finsch (1. c), in describing his C. gutturalis after the 

 specimens in the Leyden Museum, used as objects the male 

 of C. sumatramis and a female of C. gutturalis, as we 

 learn from his remarks about the female. 



174. Criniger ruficrissus. 



Criniger gutturalis Salvad. Ucc. Born. p. 207 (partim) i). 

 Criniger ruficrissus Sharpe, P. Z. S. 1879, p. 248; id. Cat. B. Br. 

 Mus. 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. sumatranus 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. ruficrissus 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 doubts to C. 

 gutturalis, though it is larger and darker above and below, undoubtedly 

 belongs to the present species.
