M. C. Z. 29405 (3 specimens). 
The dorsal varies from 293 to 313, and the anal from 27} to 293. 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.
