370 THE ZOOLOGIST. 



with fluctuations in either direction, dark or light, it does repre- 

 sent the common form. Nevertheless, it is both light and varied 

 compared with the extreme or uniform dark brown form beside it 

 (No. 8), which appears to me to be the least common one of all, 

 less so than the extreme light one (No. 1) at the other end. 

 (N.B. — When I say uniform, I do not mean to include the crown 

 of the head or tips of the wings, which are always darker than 

 the rest of the plumage.) 



(10) A bird that from the dark crown of the head to the dark 

 tips of the wings is, above and below, a uniform dark browny 

 dun, yet some washes lighter than the uniform brown one (No. 8) 

 that I have spoken of. 



(11) A bird that from the dark crown to the dark wing-tips 

 is, above and below, a uniform light fawny dun. 



(12) A bird that would be the extreme light form (No. 1) that 

 I have first described, were it not that both on the throat and 

 breast the cream is encroached upon by cloudy barrings of a soft 

 greyey-brown, which extend also over the under surface of the 

 wings. Moreover, a toning of the darker colour of the general 

 upper surface encroaches a little upon the cream of the nape. 



(13) A bird exhibiting the uniform dusky dunnish colour (a 

 shade lighter, perhaps, on the under surface), but with a cream 

 patch on each side of the neck just below the head. These 

 patches are not, perhaps, of the brightest cream, but they are very 

 conspicuous, whether the bird is seen standing or flying — in fact, 

 the conspicuous feature. 



(14) A bird that would be the extreme light form (No. 1), but 

 for a distinct collar of soft brown dividing the cream of the neck 

 and throat from that of the breast. 



(15) A bird that is yellowish dun on the neck and throat, 

 mottled brown on the breast, and a fine cream on the ventral 

 surface. 



Moreover, all these birds differed, to a greater or less extent, 

 in those lighter markings of the quill-feathers, both on the upper 

 and under surface, some being lighter and some darker, following 

 in this respect the general colouring. This feature, however, is 

 only apparent when the birds fly, and I found it too laborious to 

 include. 



So far as I can be sure — judging by the lance-like projecting
