Mr. J. H. Gurney on an 



I understand that Mr. Goldie fastens the legs of his male 

 specimens with the right tarsus uppermost, and vice versa in 

 the cast; of females ; following this indication, I infer that 

 the two birds which I shall call A and B are males, and that 

 which I shall call C a female. 



The following are the measurements of these specimens com-

The following is a description of the three specimens above 

 referred to as A, B, and C : 



The bill is yellowish horn-colour, suffused with dull olive 

 about the eyes (and slightly also at the base of the upper 

 mandible), and likewise tinged with dark olive about the 

 point of the lower mandible ; the bristly hairs .which sur-

 upper surface of the head in all three specimens is a dark 

 and somewhat greyish chocolate-brown, with a few feathers 

 on the forehead, immediately adjoining the cere, edged with 

 white ; the mantle is chocolate-brown, darker in C than in 

 A and B. In C a tinge of rufous is perceptible in the feathers 

 on either side of the nape ; in the other two specimens this 

 tinge extends across the nape and on the median wing- 

 coverts : the latter are variegated with small pure white 

 spots, none of which are more than *2 of an inch across 

 (whilst most of them are less) ; and these spots in C extend 

 to some of the external scapulars. In A the number of these 

 spots, some of which are concealed, is about nine on the 

 right side and twelve on the left side ; in B only two spots 

 are to be found on each side; in C there are about fifteen on
