region has, if I mistake not, become more extensively fu- 

 liginous. 



I have recently had an opportunity of examining three par- 

 tially fuliginous Limnaeti from Ceylon in the collection of the 

 Marquis of Tweeddale, which greatly resemble in coloration 

 the example now in the Zoological Gardens ; the dimensions 

 of these three specimens are similar to those of the ordinary 

 pale phase of L. ceylonensu. I may add that the Indian L, 

 cirrhatus, though not subject to absolute melanism, often 

 occurs in a partially fuliginous plumage very similar to that 

 of the Ceylon birds to which I have just alluded. 



I may also mention that, in a cage adjacent to the one in 

 which the Ceylon Limnaetus is domiciled in the Zoological 

 Society^s Gardens, will be found an interesting newly acquired 

 example of Morphnus guianensis, from the Upper Amazons, 

 in immature plumage, but a little more advanced than that 

 described in my last paper. In this specimen the irides are 

 pearl-grey, the cere and bare skin adjoining the eyes slate- 

 colour, and the legs and feet yellow. 



Since my last paper went to press, I have seen in the 

 Museum at Edinburgh an apparently adult specimen of Thra- 

 saetus harpyia, said to have been obtained in Guiana, pre- 

 senting the following peculiarities of coloration, which I do not 

 recollect to have previously observed in this species : — A single 

 small rufous feather is apparent on the forehead ; the gorget 

 across the upper breast is blackish brown, mingled with rufous, 

 the former predominating on the upper part of the band, and 

 the latter on the lower ; many of the feathers in the small 

 wing- coverts near the carpal joint are either wholly rufous 

 or partly rufous and partly black, but in both cases narrowly 

 tipped with white ; the feathers of the flanks are of mingled 

 brownish black, rufous, and white ; the transverse bars on 

 the thighs are pale rufous ; and, lastly, the bars on the inner 

 surface of the first primary are brownish black, mingled with 

 pale rufous. 



I had not an opportunity of examining this specimen, 

 except through the glass of the case in which it is exhibited ; 

 hut this somcwliat imperfect examination enabled mc to note
