INSESSORES. 447 



nothing more is required than for the hearer to shut his eyes 

 to the neighbouring foliage to fancy himself surrounded by 

 London grimalkins of house-top celebrity. 



While in the district in which this bird is found, my atten- 

 tion was directed to the acquisition of all the information I 

 could obtain respecting its habits, as I considered it very 

 probable that it might construct a bower similar to that of 

 the Satin-Bird ; but I could not satisfy myself that it does,

Head and back of the neck olive-green, with a narrow line 

 of white down each of the feathers of the latter ; back, wings, 

 and tail grass-green, with a tinge of blue on the margins of 

 the back-feathers ; the wing-coverts and secondaries with a 

 spot of white at the extremity of their outer web ; primaries 

 black, their external webs grass-green at the base and bluish 

 green for the remainder of their length ; all but the two cen-

 lowish green, with a spatulate mark of yellowish white down 

 the centre of each feather ; bill light horn-colour ; irides 

 brownish red ; feet whitish.

 parts of the country, C. maculata of the east coast, C. cervini- 

 ventris of Cape York, and C. f/uttata of the north-western 

 districts. 



Some parts of tlieir economy are more astonishing than
