CROTOPHACxINJl. 
This bird was discovered in Borneo, where it is constantly found on the ground searching for insects, its movements 
being performed by a rapid jumping run. 
C. radiceus (Temm.) PI. col. 538. 
Zanclostomus Swains* 
Bill moderate, with the cuhnen and lateral margins greatly curved : the sides much compressed, the 
upper mandible at the base dilated over the lower ; the gonys curved downwards ; the nostrils basal, 
lateral, longitudinal, and linear. Wings moderate and rounded, with the fifth, sixth, and seventh quills 
the longest. Tail lengthened and graduated. Tarsi rather longer than the outer anterior toe, and 
covered with broad scales. Toes moderate, the outer lateral toes nearly equal. 
These singular birds inhabit India, its archipelago, and "Western Africa, frequenting thick bamboo jungles and close 
hedges, amongst which, however prickly they may be, they make their way with great facility, seeking various 
orthopterous insects, on which they feed. They are sometimes seen perched on the lofty trees, the trunks of which 
they search for insects and their larvae.

* It was in the Class, of Birds (ii. p. 323.) that Mr. Swainson established the above genus. 
t The Appendix to the Memoir of Sir T.S. Baffles (p. 671.) contains this genus, which was established by Vigors in 1830. Bubutus 
(1831) of M. Lesson, Anadcenus (1837) of Mr. Swainson, and Idiococcyx (1838) of M. Boie are coequal.
