HORN EXPEDITION-AVES. 
The sexes are alike in plumage. 
Habitat. —McMinii’s Range, Central Australia. 
Type .—In the Australian Museum, Sydney. 
A female was also obtained at Davenport Creek ; it is scarcely adult, having 
the skin around the gape yellow and the patch of yellow feathers at the lower corner 
of the ear-coverts not so bright or well-detined, otherwise it resembles the adult 
male; length of wing, 3'03 inches. 
This very distinct species of Ptilotis I have named after Mr. George Arthur 
Keartland, whose assiduity and perseverance as ornithological collector contributed 
so much to the success of this branch of the work of the Expedition. P. keartlandi 
comes nearest to that section of the genus Ptilotis which includes P. cratitia 
and P. plumulus. 
[The first example of this species was obtained in a gorge near the police camp 
at Illamurta, as it came in company with Emblema picta to drink at a small spring. 
They were frequently found afterwards in malice, niulga, or acacia scrub, either in 
pairs or single birds. They seemed to be at constant feud with Ptilotis penicillata. 
Whenever the two sp(;cies met, one invariably chased the other away. A. nest 
of this species closely resembled that of Ptilotis clirysops.^ 
Mr. Keartland has since sent me two eggs of this species taken from a nest 
built in a low bush near Crown Point, on the Finke River. One specimen is of a 
pale heshy-buff ground colour, very sparingly and minutely freckled with light 
chestnut red except on the thicker end, where intermingled with line underlying 
streaks of faint purple the marks become confluent and a cap is thei’e formed ; 
length, 0'7 inch x 0‘58 inch. The other is of a warm bufi'ground colour, minutely 
dotted and irregularly spotted with ditlerent shades of chestnut-red, the markings 
predominating as usual on the thicker end ; length, 0'75 inch x 0'6 inch.
