it stood either as the old well-known C. jperdcus 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 has since 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 . Jlavicrissus 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. 



Mr. 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 ^. 



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. He also says the iris is blue ^. 



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.
