it stood either as the old well-known C. persicus or its synonym, C. icteronotus; as 
C. chrysonotus of Peru and Bolivia, or as a distinct species, C. vitellinus. It ultimately 
proved to be inseparable from a species of Western Ecuador described by Mr. 
Sclater in 1860 under the specific name it now bears!. It hassince been traced further 
along this coast to Western Peru® and into the Magdalena? and Cauca ® valleys of 
Colombia. In the State of Panama we have no tidings of it beyond the line of 
railway. 
The bird most nearly allied to C. flavicrissus is certainly C. persicus, but it may 
readily be distinguished by the amount of yellow on the tail, which in the former 
occupies less than half, and in the latter nearly two thirds of the base of the rectrices. 
Myr. Wyatt found C. flavicrissus on the banks of the Lake of Paturia, in the Magdalena 
valley, where there were several colonies nesting in the month of March in the low 
bushes which overhung the water. Most of the pendulous nests were within reach of the 
canoe ; they were not all of the same pattern, some having the entrance at the top, so as 
to form a long narrow bag; in others the top was roofed over, and the entrance was at 
the side. The hen lays two cream-coloured eggs, blotched with purple and brown. The 
iris of the living bird is pale blue 2. 
Salmon also found this species breeding at Remedios 2360 feet above the sea. The 
eggs he brought home are described as white, sparingly spotted with dark brown, chiefly 
at the larger end. THe also says the iris is blue 3. 
Mr. C. J. Wood’ observed C. flavicrissus to be very abundant at Turbo, where it was 
always seen in large parties and very noisy, especially in the morning, though their notes 
were, he considered, rather agreeable.
