The type oi 1'. cercicalis as well as No. 1 (of the above list) are both immature. 

 The "species" has nothiug to do with Phibjilor cnjthroccrcus, with which it has 

 been compared iu the original descrii)tioa ; bat is very closely allied to Automolus 

 infiiscatus {= sclateri auct.). Indeed, it is so near the latter that I only 

 reluctantly allow it to staud as a dilfereut form. Specimens Nos. 3 — 7 are exactly 

 like the typical examples. This series dillers from typical Peruvian skins only iu 

 having the top of tlie head decidedly rufescent, iu slight contrast with the olive- 

 brown back. In tiie birds from N.E. Pern the head is olive-brown like the back, only 

 the forehead being slightly tinged with rufescent. A good series from the Caura and 

 Orinoco Bivers agrees in every respect with Guiana skins, and the specimens of 

 Automolus scl'ttcri from British Guiana iu the British BInseum are also absolutely 

 identical with the type of 7-". cervicalis! Although the colour of the crown serves 

 to distinguish most specimens of the two subspecies, I may remark that one male 

 from British Guiana (No. 4) and two skins from the Caura are hardly dill'erent from 

 Peruvian examples. Immature birds show slight greyish edges to the feathers of 

 the foreneck, producing a mottled appearance,
