FISH, THE PEOPLE OF THE SEA 



several distinctive blue and black patches of colour 

 which, however, are not absolutely invariable in 

 every specimen. It may be that these marks come 

 and go ; they do not, however, change rapidly, 

 if at all. 



The black angel is blackish or brown or grey 

 with a diaper of gilt scales. The underside of his 

 pectoral fins is an exquisite yellow, with which 

 also his tail is tipped. He has a white muzzle 

 and a fringe of teeth that are like a solid mass 

 mounted in a pair of jaws which fold or extend 

 like a fancy folding kodak. 



The Spanish angel has a rich velvety black head 

 and tail, but the body is of a flaming cadmium 

 gold. 



Among the coral rocks may occasionally be seen 

 two or three other fish which resemble the angel 

 fish that I believe have no local names, a black 

 fish of the characteristic angel shape with trans- 

 verse yellow lines which are sometimes white, and 

 another with broad white and black stripes. It 

 may be the latter belongs more to the family of 

 "four eyes," a small yellow or whitish fish with 

 a fine herringbone pattern of blue all over and 

 a large round black spot near the tail. Like these 

 also is another without the round spot, but a black 

 stripe over the head and nose. These are the eyed 

 chseto* and the striped chseto.* They have a 



* Chsetodon capistratus and Chsetodon striatus.
