Ibis -species is rather connnon on the islets in the rivers Yenisei and .Abakan, where 

 occm-ring in grass-grown places, in thickets, etc., in full flower at the beginning of June. 

 Specimens taken in different knalities prove to be rather vaiying in i)uhescence. in the

 P. patens 'I'riuv.AN. is undoubtedly very nearly allied to P. corhisoidesL., and 1 am 

 inclined to look upon it as an eastern subspecies of the latter. Their geographical distri- 

 bution also seemed to be indicative of this assumption being right. My specimens, col- 

 lected in the transition zone between the geographical areas of the two said species, 

 thus seemed, in many respects, lo constitute intermediates between them. 



Distribution: Priiiuild jxiirns occurs in eastern Asia, westwards to about the Altai 

 region. In western Siberia it is replaced by Priiniila corlusoidrs I,.
