black with a narrow white edge and a white streak curving from first 

 spine back and up to posterior margin of fin. 



129. Chaetodon pictus Forskal. 



No. 8133a, C. M. One adult specimen. It has twelve fine dark 

 lines obliquely crossing the body below and six above, with the addi- 

 tion of a short one running from the base of the pectoral. This agrees 

 with Forskal's original description, with the exception of the short 

 line. It also agrees in this respect with the figures given by Russell 

 and by Bennett under the name of Chcetodon vagahimdus. Bennett's 

 picture is the best in general color-markings, that by Russell having 

 the dark color of the anal and dorsal too sharp on the anterior edges 

 where it should be blended with the body-color. Day publishes a 

 picture which represents either a different color-phase (perhaps of the 

 young) or a different species. The lines are much coarser and more 

 numerous, and the basal caudal bar is more crescent-shaped. 



Genus Heniochus Cuvier, 



130. Heniochus macrolepidotus (Linnaeus). 

 {Chaetodon actiminatus Linnaeus, with page-priority). 

 No. 8134a, C. M. One large specimen. 



Genus HoLOCANTHUS Lacepede. 



131. Holocanthus nicobariensis (Bloch). 



No. 8135a, C. M. Two small specimens collected from rock-pools 

 at Mount Lavinia. One of them, seven-eighths of an inch long, has 

 a semicircular stripe across the snout, one behind the eye, one opposite 

 the middle of the pectoral, one at the caudal base, and one between 

 these two last. A little larger specimen has intermediate narrower 

 stripes and is nearly identical in markings with a specimen an inch 

 and one-half long of H. bishopi Scale from Okinawa. The last, how- 

 ever, has a black caudal stripe, while the Ceylon specimens have the 

 caudal entirely colorless. 



Family HEPATID.F:. 

 Genus Hepatus Gronow. 



132. Hepatus triostegus (Linnaeus). 



No. 8136a, C. M. Two small specimens taken in a tide-pool.
