THE BIRDS OF AUSTRALIA. 
“ Collocalia francica zoonava. Differs from C. f. terrceregince (Ramsay) in 
being much darker on tbe under-surface, and in having the light band on the 
rump brownish -white. Wing, <J, 110 mm. Johnston River, North Queens- 
land.” I have not mauxtained this form, as it may be that the characters are 
those of the first plumage, ‘and there is no series enabling the discrimination of 
the young, these having the adult feathering from the nest with probably a 
slightly darker shade and a shorter wing. 
A painting of this bird sent to Gould (and now in my possession) has : “ This 
Swallow was also collected by Mr. Broadbent, on the coast range of Rocking- 
ham Bay. First seen at Dalrymple’s Gap, they appeared to come from the 
north and return again in the evening. In the morning before rain this bird 
assembled in large flocks and just skimmed over the ground with great 
rapidity. They were all leaving about the latter part of June.”
