Chsetodon falcula, Block, Ich. ix, p. 102, t. 426, fig. 2; Day, Fish. 

 India, p. 104, pi. xxvi, fig. 5 (from a drawing). 



D. 12-13/(24) 26-27. A. 3/22-23. L. r. 28. L. tr. 6/12. 



Length of head 3^ to 4, height of body 1| in the total length. 

 Eyes diameter 4 in length of head, nearly 2 from end of snout, 

 and 1 apart. Snout produced, pointed. Preopercle serrated. 

 Fins last dorsal spine longest; soft portion of fin rounded; 

 caudal almost square ; ventral reaching as far as anal ; pectoral 

 equal to the length of the head behind the angle of the mouth ; 

 second anal spine strongest and rather the longest, equal to last 

 dorsal. Colour body and head of a rather reddish lilac-purple, 

 becoming primrose posteriorly and on the fins. A dark white- 

 edged ocular band, narrower than the orbit, commences before the 

 dorsal fin, and is continued through the eye on to the interopercle. 

 A black band, widest above, from the first 4 or 5 dorsal spines to 

 below the lateral line ; a second, angularly pointed in front, from 

 last three spines to lateral line ; a third over free portion of tail ; 

 these bands, which are triangular in the young, descend down on 

 the body in adults. Twelve to fourteen vertical narrow black 

 bands on each side. Soft dorsal with a narrow black margin ; 

 caudal with a black and white posterior edge ; anal with a white 

 outer margin, a black intramarginal band, and two more bands 

 parallel to it. 



Hob. Seas of India to the Malay Archipelago, and beyond. This 

 species attains to at least 8 inches in length.

D. 12-13/23-25. A. 3/20-22. C. 17. L.r. 43/33. L.tr.5-6/15. 



Length of head about 3 to 4, height of body If in the total 



length. Eyes diameter 3g in length of head, 1| diatn. from end 



of snout, and also apart. Snout rather produced and pointed. 



Preopercle finely serrated, most strongly so at its angle. Fitis 



dorsal spines moderate ; soft portions of dorsal and anal obtusely 

 angular ; second anal spine equals the length of the third ; caudal 

 rounded. Colour a black white-edged ocular band descends to 

 the angle of the interopercle. Numerous parallel dark bands pass 

 obliquely downwards and forwards from the back, from the lowest 

 of these other similar bands run obliquely backwards. A black 

 band commences on the dorsal spines, and, growing broader, curves 

 downwards over the soft dorsal, root of tail, and part of anal.
