 I am unable to say whether these differences are due to age. 

 " The New Gruinea Spine-taiJed Swift was quite a common 

 species, especially along the open beds of the large rivers, 

 where, towards evening, numbers hawked backwards and 

 forwards close over the surface of the water. It has an 

 extraordinarily swift flight, and, as it dashes past, offers most 

 sporting shots, almost the only ones it is possible to o-et in 

 that densely wooded country." — C. H. B. G.

" I only observed the Moustached Swift in the mountains, 

 where quite a number were met with ; but as they perched 

 on the topmost branches of some very tall dead trees, only 

 two were procured. They have an exceedingly graceful 

 and striking flight, and utter a pretty warbling song. 

 Mr. Goodfellow tells me he saw a smaller species of this 

 Swift on the coast in September, but he could not secure 

 specimens." — C. H. B. G.
