SICKLE CITjETODON. 



Chsetodon Falcula. C. albo-favcscens, capite fascia curvata 



nigra, corporc diiabus breiibusfalciformibus. 

 Yellowish-white Chaetodon, with a curved black band across 



the head, and two short sickle-shaped bands across the body. 

 Chsetodon Falcula! Block, t. 426. f. 2. 



IN shape and general appearance very nearly 

 allied to the C. setifer, but differs in colours, and in 

 the want of the lengthened ray at the hind part of 

 the dorsal fin : colour white, with a tinge of yellow : 

 scales very large, a black bar across the head, as 

 in the preceding : a second, of a curved form cross- 

 ing the middle of the body, from the dorsal fin 

 downwards, but vanishing before it reaches the 

 abdomen, and a third still more curved, or of a shape 

 somewhat resembling a sickle, crossing the hind- 

 part of the body, from the middle of the dorsal 

 fin, and like the former vanishing before it reaches 

 the abdomen : the base of the tail is crossed by a 

 black bar, and tipped with black. Native of the 

 Indian seas.
