460 Mr. W. R. Ogilvie-Grant on the Genus Turnix.

remaining lighter round the margin only, while on the back 

 the rufous gradually dies out and gives place to more sombre 

 grey and black, and most of the white spots and markings 

 disappear ; the bill, too, becomes yellow instead of brownish 

 green. 



In this, the fully adult plumage, this species was named 

 T. nigrescens by Lord Tweeddale, partly on account of the 

 darker colour of the upper surface and partly on account of 

 its larger size, which is clearly due to age alone. Mr, John 

 Whitehead recently procured two pairs of this bird in 

 Palawan, in the " nigrescens " or fully adult stage, which he 

 has been kind enough to lend me for examination, and they 

 agree in every particular with Lord Tweeddale's types from 

 Cebu, Last year Dr. W. Blasius, in the above-quoted 

 periodical, described a Turnix from Palawan under the name 

 of T. haynaldi. There cannot be the slightest doubt that 

 his description is based on an immature male of this species 

 and has nothing whatever to do with T. 7-ufilatus, Wallace, 

 much less with T. sylvatica, which belong to different sections 

 of the genus. The males of T. rufilatus and T. fasciata do, 

 no doubt, resemble one another, though the former has never 

 any rufous collar (see previous remarks on p. 447) . 



Group II. — Only two species are included in this group, 

 viz., T. rufilatus from Celebes and T. powelli from the 

 Island of Api, Sumbawa. 



Both sexes in each species have the entire chest barred 

 transversely with black and white ; and while in the adult 

 females the throat is similarly coloured to the chest, in the 

 males it is white with just a few of the outer feathers edged 

 with darker.

In none of the specimens before us is there any trace of a 

 rufous nuchal collar, and the general tone of the upper 

 surface is brown, becoming reddish brown towards the rump
