Thirteen specimens 3 to 4 inches long from Manga Reva, February 4, 1905. 

 M. C. Z. 29405 (3 specimens). 



The dorsal varies from 29? to 3I2, and the anal from 272 to 292. These were 

 taken among the coral reefs. The following color note made by Mr. Chamber- 

 lain was in the bottle with the specimens : — " They are quite dark in color, 

 showing indistinct darker stripes, which are plainest on caudal region and back; 

 faint pale stripes show on dorsal and anal." 



The bodies of the specimens show no stripes, but they are evident on the 

 fins; pectoral pale yellowish; the upper ray being margined with black; dorsal 

 and anal each have a narrow black margin. These fins are usually much darker 

 than body color, but in a few specimens they are about the same color; caudal 

 deeply lunate when spread, and appears forked when not spread, the upper and 

 lower rays being greatly produced, this fin is usually darker in color than the 

 body, the rays being darker than the membranes and in some instances the outer 

 rays are each margined with white, the lunate border shows in all the specimens 

 with a narrow margin of white.
