Two adult males and a female, all collected at Nanga 

 Raoen, where we found it in low forest, and three speci- 

 mens from Poetoes Sibau, the Upper- and the Lower Ma- 

 hakkam, collected by Dr. Nieuwenhuis. The specimen from 

 the Lower Mahakkam is immature, showing some remnants 

 of the brown-spotted dress of the young bird, especially 

 on neck and upper wing-coverts. — Iris cofiee-brown, bill 

 glossy black, feet purplish white. 



The male N° 1254 and the female N° 1255 (matched) 

 were shot near their nest (N° 1248^) on May 15*^ in an

 tree ten feet above the ground, and consists of a coating 

 of dead leaves lined with rootlets, small feathers and the 

 abdominal scales of a snake. It contained two eggs of a 

 bluish green color, very thickly speckled all over with 

 reddish brown. Size of the eggs 2,3 -|- 1,8 cm. As both 

 eggs were already fairly set, it is very probable that two 

 is the regular number of the clutch in this species. 



This exclusively Bornean species is known from the south- 

 eastern, southern, western, north-western and central parts 

 of the island. In the North it is represented by the white- 

 crowned C. Stricklandi Motley & Dillwyn.

 förmig gehaltenen und stark bewegten Flügeln und wip-
