heart-shaped spots of brown ; legs, yellow, feathered 
half way below the knees. 
This was a male. Another specimen, shot within a 
few days after, agreed, in almost every particular of 
its colour and markings, with the present ; and, on 
dissection, was found to be a female.

In their size and general aspect they resemble each 
other considerably; yet I have found both males and 
females among each ; and in the present species I have
