S6 ACANTHOPTERYGII. 



rather produced and rounded. A strong preorbital spine, with three teeth below it along the edge of the plate. 

 Opercular spine distinct. Teeth — villiform. Fins — dorsal spines not strong, increasing in height to the fourth 

 which equals 3/7 of the height of the body. Pectoral extends nearly to above the anal spines, the second of 

 which is very strong, longer than the third, and equal to rather more than half of the height of the body : soft 

 dorsal and anal angularly rounded ; caudal forked. Colours — a white band from the snout to the base of the 

 dorsal spines : a second from above the orbit to a little way below the last dorsal spine : a third from the upper 

 edge of the eye to the lateral-line. A wide yellow, black-margined band passes from the mouth to the commence- 

 ment of the soft dorsal fin. A large yellow blotch exists below the last half of the soft dorsal, which latter fin 

 is anteriorly edged with black : anal black in its front half and white posteriorly. 



In the young, 8. Bleeheri, Giinther, the light band bordered with black is nearly straight, and terminates 

 where the white spot exists in the adult, near the end of the base of the soft dorsal : another light band proceeds 

 from the upper edge of the eye to the base of the spinous portion of the dorsal fin ; whilst a third median one 

 goes from the snout to the base of the first dorsal spine. 



Habitat. — Andamans and Malay Archipelago. The specimen is figured life-size.

Length of head 1/4 to 4|, of caudal 1/5, height of body 3i to 3f in the total length. Eyes — diameter 1/3 

 of length of head, 3/4 of a diameter from end of snout, and 1 apart. Scaleless portion of the head covered 

 with numerous small pores. The maxilla reaches to below the first fourth of the orbit. Preorbital sjDine strong, 

 the plate denticulated on the edge beneath it : lower edge of suborbital ring of bones serrated. Vertical limb of 

 preopercle strongly serrated, most coarsely so upon its produced angle. Opercular spine well developed. 

 Shoulder-bone serrated. Teeth — fine. Fins— the dorsal spines which are rather weak increase in length to the 

 fifth, the height of which nearly equals half the length of the head. Pectoral not quite so long as the head : 

 anal spines of equal strength, the longest equalling the extent of the postorbital portion of the head : caudal 

 deeply forked. Lateral-line — curves to opposite the end of the dorsal fin, from whence it proceeds direct to the 

 centre of the caudal. Colours — back olive, a yellowish- white band goes from the snout to the base of the dorsal 

 spines : a second from above the orbit to the end of the base of the dorsal fin : a third from the snout, where it 

 arises in common with the one for the opposite side, passes through the upper portion of the eye and at the 

 shoulder divides into two, one being above the lateral-line and becoming lost on the back of the tail, the other 

 going below the lateral-line being lost on the last fourth of the body : a fourth goes along the preorbital and 

 suborbital ring of bones being lost above the base of the pectoral fin which has a black spot in its axil. Most 

 of the scales below the lateral-line in the anterior two-thirds of the body have a black spot at their bases. A 

 violet mark is present at the base of either lobe of the caudal fin. 



Habitat. — Red Sea and Andaman islands, where it is very common. Specimen figured is 6 1 z p inches in 

 length.

B. v, D. V°, P- 17, V 1/5, A. a c. 17, L. 1. 44, L. tr. 5/14. 



Length of head 1/4, of caudal 1/5, height of body 4/15 of the total length. Eyes — diameter 1/3 of length 

 of head, nearly 1 diameter from end of snout and also apart. Upper surface of the head flat, and the scales 

 extend forwards nearly to the nostrils. Preorbital bone with one flat spine having three small teeth at the 

 anterior-inferior edge of the plate, the depth of which equals half the diameter of the orbit : infraorbital ring 

 of bones finely serrated. The maxilla reaches to below the front edge of the orbit. Vertical limb of preopercle 

 almost evenly serrated as well as its rounded and somewhat produced angle. Shoulder-bone serrated. Teeth — 

 villiform. Fins — dorsal spines slender, increasing in length to the fourth which equals 3/7 of the height of the 

 body. Second anal spine stronger but not so long as the third which equals 3/10 of the height of the body : 

 caudal forked. Lateral-line — makes a very gradual curve to below the end of the soft dorsal fin. Colours^ — 

 olive with a deep black band, one scale wide, passing from the snout through the eye to above the base of the 

 caudal fin, until it arrives below the end of the dorsal fin it is inferior to the lateral-line : fins immaculate. 



Habitat. — Andamans to the Malay Archipelago. Specimen figured is 5 inches long.
