THE BIRDS OF AUSTRALIA. 
measuring 3*5 inches, and with the upper parts being more strongly washed 
with olive, and ranging from Cape York south to the Herbert River. 
With a knowledge of New Guinea forms Hartert concluded that these 
were only subspecifically separable from C. megarhyncha of that country. 
I examined the series for the preparation of my “ Reference List ” 
and agreed with that disposition and also with Gray’s separation of the Cape 
York and Brown’s River and revived his names, which are in no sense 
doubtful. I thereupon arranged thus : 
Colluricincla megarhyncha rufogaster Gould. 
New South Wales. 
Colluricincla megarhyncha cerviniventris North. 
South Queensland. 
Colluricincla megarhyncha gouldii (Gray). 
Mid Queensland. 
Colluricincla megarhyncha griseata (Gray). 
North Queensland. 
With the recognition of the genus name Caleya this arrangement was 
followed in my 1913 “ List,” but in the following year I named 
Caleya megarhynchus normani. 
“ Differs from C. m. cerviniventris in being much paler underneath. 
Norman River, Queensland.” 
There is not sufficient material absolutely to determine the facts, but I 
am inclined to the opinion that C. rufigaster and its subspecies C. m. normani 
and C. m. cerviniventris constitute a distinct species from the northern group 
“ parvissima” i.e., C. m. gouldii and C. m. griseata, which are certainly ref erable 
to the megarhyncha birds. 
Campbell recording a specimen from Moa Island, Torres Straits, under 
the name Colluricincla parvissima has written : “ Evidently a good northern 
race of rufigaster, being smaller, lighter coloured (buff-brown), and not so 
striped on the breast as the more southern form. The male is larger (wing 
98 mm.) and browner (russet) on the secondaries and wing-coverts than the 
female (wing 93 mm.) — characteristic sexual distinctions, no doubt. Caleya 
megarhyncha (Quoy et Gaimard Voy de VAslrol, I., p. 172, pi. 3), cited by Mr. 
Mathews, has a dark-coloured (warm sepia) upper -surface, likewise a New 
Guinea specimen in the National Museum, with its olive-brown back, and 
is therefore unlike parvissima. Again, Mr. Mathews gives priority to Gray’s 
two names, gouldi and griseata, over parvissima. According to a good 
Australian authority, the late Dr. E. P. Ramsay, both Gray’s names are 
doubtful as to species. That two distinct species should exist on islands so 
close to each other (and to the mainland) as Barnard Islands and Dunk Island
