Mitchell’s Slenderfoot. 
Leptopus Mitchelli , Fraser, Proc.* Zool. Soc. 1844, p. 157, 
Leptodactylus Mitchelli , ibid. 
The bill of this bird is of the same structure as that of Totcmiis chloropijgius, Vieill., while 
the feet resemble those of Hiaticula tricottaris; thereby rendering it particularly interesting, as 
being directly intermediate between two groups hitherto considered by naturalists as belonging to 
distinct families. Its habits remain as yet to be recorded. 
The Leptopus Mitchelli has hitherto only been found in the swampy places of the Andes, 
central Chile. 
Front, cheek, and throat, soot-coloured; crown of the head, the same, surrounded by a white 
line; nape and sides of neck, rusty; upper surface of body, grey-brown, with purplish reflections; 
a band across the chest, white; under surface, minutely barred with brownish black and white, 
alternately; bill, greenish; legs and feet, yellow; claws, black. 
Another specimen, which I take to be the young of the above, has an undefined white line 
passing from eye to eye round the back of the head; the whole upper surface of the body, 
irregularly barred and mottled with ferruginous and blackish brown; cheeks and throat, mottled 
with soot coloui, the breast barred in a similar manner to the adult, which barring is almost lost 
on the belly; vent and thighs, white. 
Total length, seven inches.
