106 ^Ir, W. R. Ogilvie-Grant on the Birds collected 



always witli the most harmonious shades. It would seem 

 as though Nature had almost exhausted her scheme of 

 coloration in dealing with some of tliese birds ^ for we 

 find two totally diftevent species^, Ptilopus zonurus and 

 P. yestroi, occurring together in which the markings and 

 colours of the plumage are almost identical ; on the under- 

 surface the two species are practically alike, both have the 

 chin and throat pale lavender, extending in a ring round the 

 neck, the fore-neck orange, the chest Avashed with vinous- 

 brown, and the remainder of the under-parts green; on the 

 upper-surface the top of the head and nape are greenish- 

 yellow and the rest of the ujiper-parts green, but in P. zonurus 

 the median wing- coverts are green with a subterminal spot 

 t>f bright pink, while in P. gestrui the least wing-coverts are 

 crimson and the next series grey fringed Avith greenish- 

 yelloAV. Another parallel case of close resemblance is 

 found between the small Ptilopus nanus and the larger 

 P. coronulatus. Though really extremely distinct species 

 the underparts are very similarly coloured, both being 

 green with a bright magenta patch on the middle of the 

 breast, and the belly and under tail-coverts mostly bright 

 yellow : vicAved from the upper surface the tAvo birds are, 

 however, very different, P. coronulattis having the crown 

 lilac-pink, edged posteriorly Avith bands of crimson and 

 yelloAv, Avhile P. nanus has the head green, but the ends of 

 the scapulars and secondaries are deep shining bluish-green, 

 tipped with bright yellow. Even more brilliantly coloured 

 species than those already mentioned are Ptilojms putchethis, 

 P. s}tpert)us, P. aarantiifrons. and P. bellus. 



Near the camp at Wataikwa large flocks of D'Albertis' 

 Pigeon {Gijmnophaps alhertisii) were observed coming in 

 every evening from their feeding-grounds on the high 

 mountains to roost on the plains below. Mr. Goodfellow 

 tells us that their flight is extremely rapid and that their 

 strange aerial evolutions remind one of the common
