The real affinities of this rare form have never been recognised. Mr. Sclater, 

 in his review of tlie genns,* included it in the section of P./lnvipes. This, 

 however, is not its proper place, and a thorough study of all members of the genus 

 proved it to be a geographical race of P. thorarka (Temm.), most nearly allied to 

 P. t. gnseiventris (Berl. & Hart.), t 



It agrees with them in the coloration of the under-snriace of the wing and in 

 having the forehead and vertex tinged with yellowish olive, the occiput and nape 

 being pure cinereous. The abdomen is ]iale cinereous, as in P. t. i/i'iseiten/ris. 

 The Para form diflFers, however, from lioth by having the sides of the head and 

 neck ashy grey instead of yellowish olive-green, and by the lack of the olive- 

 yellow jugular band. Yet, in one of the two specimens (No. 307) there is a faint 

 yellowish tinge to be seen across the chest, thus indicating the close relations to 

 P. tkoracica. Therefore I have not the slightest doubt that the three forms 

 with olive-yellowish forehead and grey nape form a natnr;il group, consequently 

 they must be designated by trinomials. 



As pointed out by Berlepsch and Hartert,t P. pectoi-alis (Scl.) is quite a 

 different species, easily recognisable by having the whole top of the head (from 

 the fnint to the nape) pure cinereous, the middle of the alidomeu white, and by the 

 yellow pectoral band being much brighter and extended over the whole chest. 

 This is an exclusively Amazonian species, ranging from Mattogrosso to Cayenne, 

 Surinam and British Guiana. In Tring there are more than twenty specimens 

 from the three latter countries, which I am unable to distinguish from Sclaler's 

 type (ex Mattogrosso — Natterer). 



In another jiaper I intend to discuss the distribution of P. thoracica and its 

 allies.
