168 XOVITATKS ZOOLOGICAE XXI. I'JIJ. 



more like the Peruvian fonu, tiiongli as a rule the lielly is somcwliat deeper ciiina- 

 mou rnfons, and the tliroat more mixed with greyish. The back and riim]! are rufous 

 Ijrown, the dark ferruginous wing-bands narrow as in 0. /. oenaiitlioides, and the 

 tail nuiform black. The greyish (not deep brown) pilenm and the narrow, 3'ellowisli 

 white superciliary streak render it easily recognisable among its allies. The 

 sjiecimens IVom South-eastern Peru are practically identical with the Bolivian cues. 

 I have named this well -characterised form in compliment of Count Hans von 

 Berlepsch, the celebrated authority on >South American birds. 



TT. Euscarthmus zosterops Pelz. and its allies. 



In Nor. Zool. vol. xvii., December 1910, p]). 2^9-291 > I have given a short 

 review of the three races of E. striaticollis known at that time. Since then 1 

 have had the opportunity of coiujiaring the specimen from East Ecuador (Rio 

 Santiago ; coll. E. Festa) in the Turin Museum with the types of E. zosteroiJS 

 Pelz. and three skins from North-eastern Peru in the collections of the Jardin des 

 Plautes at Paris. While the Ecuador bird jiroves to be identical with typical 

 E. s. zosterops, the Peruvian representatives show several well-marked ditferences, 

 and- constitute undoubtedly a distinct race, which, in its characters, stands 

 somewhat between E. striaticollis zosterops Pelz. and E. striaticollis johannis 

 Suethl. 



I propose to call it 



Euscarthmus striaticollis amazonicus n. snbsp. 



E. snuteraps (nee Pelzein) Scliiter & Salviu, P.Z. S. 187«, p. I'M (Moyobumlja, East Peru). 



Adult. — Above similar to E. striaticollis johannis Snethl.*, having the whole 

 pileum, like the back, bright green, the edges to the upper wing-coverts 

 yellowish green, and the dingy white throat conspicuously, though narrowly, 

 streaked with dusky ; but it may be easily distinguished by its much paler 

 sulphur-yellow belly, more greenish foreneck with obsolete dusky streaks, whitish 

 (not rusty buff) lores, darker brown ear-coverts, and much jialer yellow axillaries, 

 as well as under wing-coverts. Wings and tail shorter.

Obs. — The type is in good, freshly moulted plumage, while the others, 

 especially the " S " marked " 1847, No. 1361," are somewhat worn. Nevertheless 

 there is hardly any difference in coloration between them. The upper parts are 

 bright green, as in E. s. johannis, the forehead and crown without any trace of 

 cinereous or brownish suffusion; the feathers of the crown are slightly lengthened 

 as in the other members of the group. The inner secondaries (tertials) have a 

 distinct, yellowish-white margin along the outer web. In the males, the upper 

 wing-coverts are edged with olive green, scarcely different from the colour of
