Plate 5. 



Fig. 10. A group of large coral-reef fishes over a rock cleft in front of branching 

 gorgonians. At the left two surgeons (Hepatns hepatus). The lancet is 

 visible in the one at the right. A third surgeon at right of middle below 

 also shows the lancet. These fish are practically black. In the center a 

 French grunt {Hamtdon flavolineafum), striped with yellow and blue. 

 At the left of this a blue parrot-fish (Callyodon caruleus) ; at its right a 

 green parrot-fish (probably Callyodon vetula). Beneath the green parrot- 

 fish a mottled parrot (Sparisoman- Above the grunt a second mottled 

 parrot and to tlie left of this a third. Behind the green parrot a purple 

 sea-fan {Rhipidogorgia). Note the position of the pectoral in the par 

 rots and the left-hand surgeon. 



Fig. II. A group of large coral-reef fish, chiefly yellow and blue grunts, mostly Htrmu- 

 lon schirus. Among these at the left one or two gray snappers (Lutianus 

 grisciis). At the right are purple sea-fans (Rhipidogorgia) and to the 

 left of these two large parrot fish. In front of the lower parrot fish a 

 surgeon (Hepatus hepatus). A second surgeon farther to the left shows 

 the characteristic mode of locomotion by the pectoral fins. This is seen 

 also in the lower parrot. The camera was pointed toward the light, so 

 that the markings of the fish are not as distinct as they would other- 

 wise be.
