curve. The whole upper part of the bird is blueisli ash-co- 

 lour : a white band extends over the eyes ; and a black band 

 commences at the nostrils, which, passing through the eyes, 

 is continued over the temples, and prolonged down the sides 

 of the neck : below the eyes and this black band every part 

 is white, including the cheeks : the throat also is white, and 

 the whole of the rest of the under parts are reddish rust- 

 colour, which is deeper about the neck and sides of the breast. 

 The thighs and under tail-coverts are fine burnt sienna, the 

 tips of the latter feathers being clear white : the spurious 

 wing-feather is black ; the largest has a white edge. The 

 quill-feathers are cinereous dusky, the largest white at the 

 roots. The two central tail-feathers are blueish-ash, the others 

 are black, with blueish-ash-coloured tips on the outer webs ; 

 the outer feathers have a white space between the black and 

 the gray tip on the outer web, and a square patch of white 

 on the inner web ; the next feather has some white also, but 

 in a smaller degree, as have also the third and fourth feathers. 

 There is no difference in the plumage of these birds between 

 the male and the female. 



The egg numbered 138 is that of the Nuthatch.
