 the under mandible apparently black, one dark brown, the other three 

 brownish white. 



7. CERTHIDEA. ALBEMARLEI, new species.

8. CERTHIDEA LUTEOLA, new species.

 islands, but much brighter olivaceous above and (except in very 

 abraded plumage) distinctly buft- yellowish beneath.

There are seven specimens of this very distinct form iu Dr. Baur's 

 collection, and six iu the National Museum collection. None of the 

 latter are in perfect plumage, however, and I have accordingly been 

 obliged to select one of Dr. Baur's specimens as the type. 



Two of Dr. Baur's specimens (both adult males, obtained June 17 and 

 18, while "in full song") and one of the National Museum specimens 

 (obtained March 30, and in greatly worn plumage) have the bill entirely
