Genus— ALP HACH LAM YD ERA. 
Alphachlamydera Mathews, Austral 
Avian Record, Vol. II., pt. 5, p. 112, 
Sept. 24th, 1914. Type (by original 
designation) .. .. .. .. Chlamydera cerviniventris Gould. 
I DIAGNOSED this genus thus : “ Differs from Chlamydera Gould in its peculiar 
coloration which resembles that of Rogersornis, but entirely lacks the erectile 
nuchal crest; in size it approaches nearly Chlamydera, but that genus also 
possesses a well-formed nuchal crest.” 
This form also occurs in New Guinea and is of the same size as Chlamydera 
s. str., but has the bOl like the succeeding form, while the legs are like those of 
Chlamydera. 
The wing has the third, fourth, fifth and sixth primaries subequal and 
longest, the second equal to the seventh, the first shorter than the secondaries 
but more than half the length of the third. 
The distribution of these “ Chlamydera ” may be noted here: 
This form is restricted to North Queensland, also occmriug m New Guinea; 
the next form occurs in North Queensland and Northern Territory to North¬ 
west Australia, while the preceding occms all over Northern Austraha extending 
dowm to the limits of the tropics on the west, right through the central regions 
and into New South Wales on the east. 
A species named by Reichenow, Chlamydera lanterbache from New Guinea 
does not seem to have any near relationship to this series of true “ Chlamydera" 
and in order to avoid confusion I have separated it as a distinct genus, for 
which I provided the new' name Fseudochlamydera in the Bulletin of the British 
Ornithologist Club, Vol. XLVI., p. 60, Jan. 30th, 1926.
