dilutior: rostri maxilla brunnea: mandibula albida: pedibus flavicanti griseis: long.

? mari similis, sed paulo ochrascescentius tincta. 
Hab. Chatham Island, James Island (Darwin) ; Indefatigable Island (Habel). 
Dr. Habel gives the measurement of the outstretched wings of this species as 
6f inches. He adds the following note :—* This species lives exclusively on insects, 
which it hunts through the thickest bushes in flocks, warbling its not unpleasing notes. 
It wanders from bush to bush by a short, low flight. The density of the thickets often 
renders it a difficult bird to secure.” —H. 
CERTHIDEA FUSCA. 
Certhidea fusca, Scl. & Salv. 1870, p. 324. 
Supra fusca, subtus grisescenti-albida: subalaribus et remigum marginibus internis 
albis: rostro et pedibus nigris: long. tota 3-7, ale 2-0, caude 1'5, rostri a rictu 0:5, 
* tarsi 0°8. 
Obs. Preecedenti similis sed rostro graciliore, colore, sicut pedum, nigro et veste magis 
fusca distinguenda. 
Hab. Bindloe and Abingdon Islands (Habel). 
Certhidea fusca. 
“The morning after I landed on Abingdon Island I was pleasantly surprised on 
hearing a melodious song near the tent which I had never heard before in other 
islands of the archipelago, and which reminded me of the notes of a Central-American 
Wren. Hurrying out of the tent to look for the songster, I could hardly believe my 
eyes when I saw this bird, expecting to find a Wren. Only by repeated observations 
could I convince myself that it really was the owner of so sweet a voice. 
“Its habits only differ from those of the preceding species inasmuch as it is found in 
smaller flocks. These keep flying from bush to bush, which on the arid volcanic soil 
of Bindloe and Abingdon Islands grow less densely and are more isolated. Certhidea 
Jusca lives entirely on insects.” —H.
