not seen in P. r. vufinucha, the back is a shade deeper olive-green. The bills of 

 the two subspecies are exactly of the same dimensions. 



The young birds have no chestnut nape-patch and no distinct whitish patch 

 on the forehead, the sides and flanks are not so deep olive-green, the chest is 

 washed with cinnamon.

.Sjjeciiuens from Jobi differ conspicuously in their brighter yellow abdomen 

 and under tail-coverts, and in the brownish area across the chest being tjuite absent 

 or ill-<leiined, never well developed, the chest being yellow with an olive tinge, 

 instead of j)ale brownish. The specimens from Takar, to the east of the Ambernoh 

 River, are perfectly similar to the typical Jobi form, and so is the one shot by 

 Dumas near Humboldt Bay. The last specimen, and those from Takar, make it 

 almost certain that tlie specimen said to be from the Ambernoh, is not from there.

This last specimen belongs distinctly to typical yrimceps, having the abdomen 

 and under tail-coverts very pale yellowish, and a distinctly brownish chest. In 

 view of the fact that Takar examples belong to P. (/riseicepsjobii'iisix, we think that 

 this latter form should also occrnr on the Ambernoh River, and the explanation may 

 perhujis lie in the uncertainty of the locality. The birds said to come from the
