These examples differ from Bornean, Celebean, and Moluccan 

 birds chiefly in having a very broad white superciliary streak.

 greenish yellow; tarsus yellowish green. Length 17'0 centims. ; 

 wing 8'6-9'8; bill from gape 2*0 centims. 



This Quail, though somewhat resembling T. rufilatus of Celebes, 

 is at once recognizable by the entire absence of rufous on the abdo- 

 men and thighs. The cervix is darker, the barring on the breast 

 more distinct, and extending much lower ; and the black stripe on 

 the throat of the male bird considerably more restricted. I have 

 named this species after my friend Lieut. R. ff. Powell, R.N., who 

 accompanied the ' Marchesa ' in her voyages to Kamtschatka and 

 New Guinea.

This individual, the label of which is without measurements and 

 notice of colour of soft parts, has the forehead black. The whole 

 of the neck, breast, and abdomen is white, the dark grey being con- 

 fined entirely to the sides of the body, and not passing towards the 

 middle line of the abdomen as in E. phoenicura.

I have had no opportunity of comparing these skins vrith Javan 

 or Malaccan examples, and cannot therefore state to which species 

 the}' should be referred.
