pale tawny ; quills below ashy brown ; inner edge of quills rufcs- 

 cent ; "upper mandible brown, lower mandible tlesh-colour ; legs 

 flesh-colour ; iris brown " {Ayres). Total length 3-5 inches, culmen 

 0"45, wing 2"05, tail 1'2, tarsus (J-So. 



The winter plumage of the mule differs from the summer dress in 

 being very much more tawny and more striated ; the upper surface 

 generally has the centres to the feathers blackish brown, all of them 

 broadly margined with pale fulvous or tawny, with an indication of 

 a lighter collar and mantle. The rump is deeper tawny, but shows 

 signs of blackisl^ striations. Underneath, the general colour is a 

 very pale tawny buff, whiter on the alxlomen and vent, with the 

 sides of the breast distinctly striated with dark brown ; the throat 

 cheeks, lores, and eyebrow pure white ; the tail-feathers are 

 broadly tipped with white. Total length 4 inches, wing 2-05, tail 

 1-4, tarsus 0-85. 



The female in winter does not differ appreciably from the male ; 

 the only female specimen in breeding-plumage seems also much to 

 resemble the male in the worn character of the feathers, but still 

 preserves the striated head. 



The female measures : — Total length 3"7 inches, wing 1-9, tail 1'5, 

 tarsus 0*7. 



The young on leaving the nest is striated like the old female, but 

 is very pale in colour, and tinged with yellow, especially on the 

 lores, eyebrow, sides of face, sides of neck, and breast ; the light 

 margins to the tail-feathers are rather broad, the centre ones being 

 reddish brown with narrow black median stripes. 



The young after its first moidt (= C. ayresi) is more rufous above, 

 with pronounced black centres, the mantle and back varied with a 

 few greyish-white margins, the rump very decidedly rufous, with 

 narrow black striations ; under surface of body tawny buff, brighter 

 on the flanks and sides; the throat, centre of breast, abdomen, and 

 under tail-coverts white. 



A female measures : — Total length 3'8 inches, wing 1-9, tail 1-5, 

 tarsus 0'8. 



Iris light brown ; upper mandible dark hazel, under mandible 

 pale; tarsi and feet pale (Ayres). 



The type of IIemi23teryx olignra, kindly lent me by Dr. Krauss, 

 is the present bird in full breeding-plumage. Total length 3-75 

 inches, wing 2-5, tail 1-35, tarsus 0"9. 



The type of Hemipteryx iodopyga is the present species in full 

 winter plumage, and is apparently a female. Total length 3-6 

 inches, wing 2-15, tarsus 0-S. For a sight of this typical specimen 

 I am indebted to Dr. Krauss.
