FAMILY, I— PERCIDiE. 35 



Length of head 2/7, of caudal 1/7, height of body 1/4 to 2/9 of the total length. Eyes — diameter 3/10 

 to 2/7 of length of head, 1 diameter from the end of snout, and 3/4 of a diameter apart. Body elongated, its 

 dorsal and abdominal profiles nearly horizontal. The maxilla reaches to below the first third of the orbit : 

 interorbital space fiat. Vertical limb of preopercle with a moderately deep emargination to receive a very 

 badly developed interopercular knob, its angle rounded, the whole limb finely serrated, and the lower limb 

 almost entire. Two small sharp points on the opercle. Teeth — villiform in the jaws, with a large canine on 

 either side of the premaxillary, between which are two smaller curved canine-like teeth in the outer row, and 

 several more similar ones along the upper jaw : in the lower jaw exists an outer row of curved, canine-like 

 teeth, becoming larger posteriorly : in a triangular spot of villiform ones on the vomer, the base being behind, 

 and from the centre of which a narrow band passes a short way backwards : those on the palatines in a narrow 

 line : an oblong patch on the tongue. Fins — spines weak, those of the dorsal increase in length to the third 

 and fourth, which are half as long as the head, from these they decrease to the last : soft portion of the fin, (as 

 is also that of the anal,) rounded and not half so high as the spines, the longest ray equalling two-thirds the 

 length of the base of the fin. Pectoral extends rather beyond the ventral, but hardly to above the anal, it is two- 

 thirds as long as the head : third anal spine rather the longest, equal to the diameter of the orbit but not so long 

 as the rays, anterior anal rays one-third higher than those of the dorsal, last anal ray as short as the spine, lower 

 edge of fin straight : caudal slightly emarginate. Scales — in parallel rows below and oblique ones above the lateral 

 line. Colours — yellowish-grey superiorly, becoming yellowish-white on the sides and abdomen, a broad black 

 band passes from the eye to the middle of the caudal fin, dividing the dark back from the light sides, and a 

 second band is continued from below the jaws to above the posterior end of the base of the anal, where it 

 becomes indistinct. A white pearly spot exists on the back under the middle of the spinous dorsal, and a 

 second under the commencement of the rayed portion of the fin. 



Professor Peters showed me one of this species, nearly 4 inches in length, received from Paris as 

 Serranus biguttatus, and I subsequently saw several more of the types in the Paris Museum. 



Habitat. — Seas of India to the Malay Archipelago. The type specimen of Cuv. and Val. came from 

 Ceylon, the one figured (7| inches in length) I procured at the Andaman islands.

Length of head 2/7 to 3/11, of caudal 1/6, height of body 2/7 to 4/15 of the total length, ^yes- 

 diameter 1/3 to 2/7 of length of head 3/4 of a diameter from end of snout and also apart. The depth of the 

 cheek from the eye to the maxillary bone equals two-thirds of that of the maxillary bone. The maxilla reaches 

 to below the middle of the orbit. Vertical limb of the preopercle with a slightly produced angle and almost 

 horizontal lower limb, its vertical limb finely serrated, more coarsely so at its angle, the serrations being 

 continued along the posterior half of its lower limb : opercle with two points, the lower being the most distinct. 

 No interopercular knob. Teeth — canines in the premaxillaries and an outer row of curved canine-like teeth in 

 both jaws : villiform ones in a triangular patch, having a posterior median elongation in the vomer, and in a 

 narrow band on the palatines ; an oblong patch widest anteriorly of very fine teeth on the tongue. Fins — dorsal 

 spines moderately strong, the third to the fifth being the longest and nearly equal to half the length of the head, 

 from thence they decrease to the last which is about two-thirds of their height and equal to that of the rays. 

 Pectoral pointed, nearly as long as the head, and reaching to above the anal spines : second anal spine the 

 strongest and nearly equal to the length of the third or to the postorbital portion of the head, anal rays one-fourth 

 higher than those of the dorsal fin. Scales — in oblique sinuous rows above the lateral-line to opposite the end 

 of the soft dorsal fin where they become horizontal, as are also those below the lateral-line : on the 

 summit of the head the scales extend forwards to above the anterior third of the eye. Colours — purplish-red 

 along the back, becoming more yellow below the lateral-line. In the upper third of the body there are oblique 

 and in places sinuous golden lines along each row of scales, whilst below the lateral-line there are bands of dark 

 pink, one passes along the first-third of the lateral-line and for the depth of half a scale below it : next is a golden 

 band, one scale deep, ending on the lateral-line beneath the middle of the soft dorsal : below this is a rather 

 wider reddish band passing from the eye to the lateral-line below the end of the soft dorsal : next follows a 

 yellow band one scale deep going to the middle of the tail. Below this the fish is longitudinally banded with 

 pink and yellow alternately. Fins yellow, with a light band, along the centre of the dorsal.
