near Humboldt Bay. This specimen has a somewhat larger 

 and longer bill than any o£ those listed above, but resembles 

 them in other respects. 



" This Black-throated Chestnut Flycatcher was probably 

 common, though not met with near the coast. Like M. mena- 

 densis, it frequents the lower branches and undergrowth."

This species was first described from New Ireland under 

 the above name [Garnot, Yoy. ' Coquille,^ Zool. i. p. 589, 

 pi. XV. fig. 1 (1826)], and subsequently as Drymophila alecto 

 from Celebes [Temminck, PI. Col. pi. 430. fig. 1 (1827)]. 

 Though found all along the coastal districts of New Gruinea 

 and the adjacent islands, it does not appear to occur in the 

 Aru Group, where its place is taken by AI. rufolateralis Gray. 

 The female of this latter form has the nape and upper 

 mantle dark blackish-grey and the back, wings, and tail 

 darker chestnut; whereas in M. chalyheoceplialvs all these 

 parts are bright rufous-chestnut with only the nape dark 

 greyish-black. The Aru bird has been united by Sharpe 

 with M. nitidus (Gould) from Port Essington, Australia, etc. 

 and with the birds from Tenimber Islands; but though 

 nearly allied, the females are probably separable. To study 

 this question properly, however, more material is required. 

 The Tenimber birds seem to have the tail somewhat longer
