VI TRICHOGLOSSIDAE 375 
The half-dozen crested members of Calyptorhynchus, which are 
brown or black with a greenish gloss, and a whitish, red, or 
yellow band across the lateral rectrices, have a more laboured 
flight and a comparatively low whining cry ; they feed on seeds of 
Banksia and Casuarina and on caterpillars. Callocephalon galeatum 
is grey, with a scarlet head and crest. In these two Australian 
genera the supposed females exhibit yellow markings.  Jficro- 
glossus aterrimus, the Great Black Cockatoo of North Australia 
and Papuasia, is greyish-black with a long narrow crest, and 
naked red and yellow cheeks. It is a retiring bird, found in pairs 
among high trees in thick forests; the flight is comparatively 
weak, the note a plaintive whistle; the food consists of seeds of 
Pandanus, Canarium, palm-shoots, and the like; the ege is laid 
on a bed of twigs in a hollow tree. Calopsittacus novae hollandiae, 
the crested Australian Cockatoo-Parakeet, is dark grey, with yellow 
forehead and cheeks, orange ear-coverts, and white wing-patch. 
The female has yellow marks on the tail and under parts. By no 
means shy, the flocks feed chiefly on the ground, while individuals 
fly well and love perching on dead branches. 
Fam. IV. Trichoglossidae.—Sub-fam. 1. Cyclopsittacinae.— 
This includes Neopsittacus and Cyclopsittacus of Timor, North-East 
Australia and Papuasia, which are coloured red, green, blue, and 
yellow ; the peculiarities of structure have already been mentioned. 
Sub-Fam. 2. Loriinae.— Trichoglossus novae hollandiae, Swain- 
son’s Lory, is blue, with green head and central abdomen; the 
remaining under parts being red, the sides, nuchal collar and 
inner webs of the lateral rectrices yellow. Flocks haunt the 
Hucalyptus-forests of Eastern Australia and Tasmania, uttering 
incessant screams, flying swiftly and directly from tree to tree, 
setthng again with a dash, creeping and clinging around the 
branches, and extracting honey from the flowers with their 
brush-tipped tongues, besides eating seeds. From two to four 
egos are deposited in holes in trees. The various species of 
Trichoglossus range from Celebes and Timor to Australia and the 
New Hebrides. Ptilosclera versicolor, of North and West Australia, 
is green, with yellowish streaks on the body, bluish cheeks and 
nape, red crown, lores and breast. Coriphilus taitianus of the 
Society Islands is dark blue, with the lower surface chiefly white ; 
C. ultramarinus of the Marquesas shews a combination of leht 
and dark blue.  Zorvius extends from the Moluccas to the Solomon
