Show 960 MR. G. A. BOULENGER ON REPTILES, [Nov. 28, supplemental bone ; villiform teeth in jaws and on vomer and palatines; no canines; tongue smooth; head partly naked; praeopercle serrated, with a few antrorse spines on the lower border ; opercle with two spines. Gill-membranes separate ; seven branchiostegals ; pseudobranchiae present. Dorsal tins confluent, X I V - X V 11-14, the spinous portion much longer than the soft; anal short, III 7-11; caudal rounded. Pectoral symmetrical, rounded, rays 16. Ventrals below the pectorals, close together, with a strong spine and five branched rays, the last of which is connected with the belly by a membrane. The type species of this genus of Serranidce, allied to Siniperca, is from the interior of North Corea1. It is highly interesting to add a second species from the interior of Hainan. 1. COREOPERCA WHITEHEADI, sp. n. (Plate LXVIIT.) Depth of body equal to length of head, 3 times in total length. Snout 1^ diameter of eye, which equals interorbital width, | length of head ; lower jaw projecting beyond the snout; maxillary extending a little beyond vertical of posterior border of eye, the width of its distal extremity a little less than diameter of eye ; praeorbital entire ; cheeks and opercles scaly, rest of head naked ; praeopercle finely serrated, without enlarged spines at the angle ; opercular spines strong, Dorsal X V 14, originating above base of pectoral; spinous portion twice as long as the soft; spines strong, short, increasing in length to the sixth, which equals | length of head ; longest soft rays nearly | length of head. Pectoral ± length of head. Anal III 11 ; second spine longest, a little shorter than longest dorsal spines. Caudal rounded, subtruncate. Sq. 80 ^; 1.1. 63. Brown, with dark marblings and whitish dots ; a dark streak from below the eye to the angle of the praeopercle and another from the eye to a large, black, white-edged ocellar spot 1 Having had the privilege of examining the type specimens of Coreoperca herzi, Herzenst. 1, p., preserved in the St. Petersburg Museum, I add a description of them for comparison with C. whiteheadi:- Greatest depth at origin of dorsal fin, 3 to 3^ times in total length, length of head 2 | to 3 times. Snout as long as diameter of eye. ^ length of head, and twice width of interorbital region ; lower jaw not projecting ; maxillary extending to below posterior third of eye, the width of its distal extremity about half diameter of eye ; praeorbital entire; cheeks and opercles scaly, rest of head naked ; prajopercle with two strong bifid spines at the angle and two or three antrorse spines on the lower border ; opercular spines strong. Dorsal X I V 11- 12; originating above base of pectoral, spinous portion twice as long as the soft; spines strong, increasing in length to the fifth, which equals § length of head, but is considerably shorter than~the longest soft rays. Pectoral f length of head. Anal III 7, spines very strong, tbird a little longer than first, second longest and a little longer than longest dorsal spine. Caudal rounded. Sq. 76-82 -g^ ; 1. 1. 51-56. Brown ; a dark streak from below the eye to the angle of the praeopercle; a black spot, edged with white anteriorly, bei ween the opercular spines ; body with some dark brown spots intermixed with whitish dots ; a regular series of dark spots along the base of the dorsal Total length 85 millim.
