 yellow irides. We have about thirty skins of this form and an equa 

 number of P. simplex, all nicely prepared and properly sexed, witl 

 color notes, and no difficulty is experienced in dividing them into tw( 

 lots, except in the case of birds from Subi and Sirhassen, in the Natu 

 nas, which have the plumage of the present bird, with the red irides o 

 P. slmj'le.r. We have P. simplex, with red irides, from Trong, Pul(
