from Pichincha and Corazon, Eciiailor, liowever, are absolutely identical with a 

 topotype from Central Peru, thus proving that this divergency is of no geographical 

 significance. L. godmani Las, hence, to ue relegated to the synonymy of P. 

 ophthalmicus. 



I may mention that the same difference in the shape of the bill between adult 

 and young birds is observable in many other genera of the Ti/rannidac, f. e. 

 Sublegatus, Xniojisaris, Suiriri (= Kmpithtqrct), Phaeomyias, etc.

This bird is totally ditFerent from Cap.vi'mpis flaxeola, with which it was 

 compared by its describer, but belongs to the genus Serpophaija, and has since 

 been redescribed as S. oreiioce/mis by Berlepsch & Hartert. 



Salvin's type agrees perfectly with some specimens out of the series collected 

 by Cherrie on the Orinoco. The Tring Museum has lately received several skins 

 from the environs of Paramaribo, Surinam. 



The systematic jiosition of (S'. caudata has been fully discussed by Berlepsch & 

 Hartert in the paper quoted above. It is certainly a very near ally of Serphophaga 

 sub/lava 8cl. & Salv., and a larger series from Pard might even prove their identity. 

 Comparing the unique type of the latter with our series of S. caudata, I notice that 

 it has the chin yellow like the whole under-surface (not white), no buff suffusion on 

 the foreneck and no white at all on the tail. The rectrices, however, are extremely 

 worn, and I would not lay too mucli stress upon the absence of the white markings. 



It is very unfortunate that the name 8. oreuocensis has to give way to that 

 of Salvin, who did not recognise the true position of the species.
