The two species of this genus are peculiar to New Zealand, where they are found on the bushes, searching the 

 branches and leaves for minute insects, both in their mature and larva states.

Bill long, much compressed on the sides, with the culmen straight, and the lateral margin advancing 

 upwards to the tip, which is acute, the gonys lengthened and curved upwards; the nostrils basal, 

 lateral, small, and linear, partly closed by a membrane, and hidden by the frontal plumes. Wings long, 

 with the third and fourth quills the longest. Tail long and rounded, with the shaft of each feather 

 prolonged and rigid. Tarsi shorter than the middle toe, robust, and covered with transverse scales. 

 Toes long and slender, with the lateral ones unequal, the outer toe the longest, and both united at

Mr. Darwin informs us that this bird is common in the forests of Chiloe, and in the woods south of Valparaiso. It 

 may be constantly seen running up the trunks of the lofty trees, and its food consists of coleopterous insects.

* Mr. Gould established this genus under the name of Dendrodromus in 1839, which, having been employed, was changed by me to the 

 above appellation in 1842.
