Specimens examined.

Lectotype. —RMNH-D435 (D, 267 mm standard length) from Japan, designated by Boeseman (1947).
Paralectotypes. —RMNH1047 (2 individuals: 154, 180), D2246 (320), D436 (147) from Japan.
Holotype of L. genivittatus. —MNHN9074 (157) from ?loc.
Lectotype of L. richardsonii. —BMNH18851. 12. 27. 45 (1 of 2: 98) from China, here designated.
UMUTZ18416 (98), 52677 (140), 52699 (205) from Formosa.
UMUTZ2268 (132), 49927 (155), 26538 (170), 47994 (180), 48035 (180), 41232 (240), 10284 (260), 53992 (278), 31169 (295), FAKU26027 (175) from Japan.

D. X, 9; A. III, 8; P₁. 13; P₂. I, 5; C. 8 + 7; L. lat. 47 or 48; Ltr. 6 or 7/i/15 or 16.

Proportional measurements of some specimens are shown in Table 18.

Head length less than body depth. End of jaws usually on the vertical through anterior nostril. Interorbital area convex. Third or fourth dorsal spine longest. 5 scale rows between lateral line and median dorsal spines. Inner base of pectoral without scales or sometimes with a few scales. Lateral teeth of jaws small and conical.

Color. —Grayish-brown, paler below. Two blue streaks radiating from eye forward sometimes conspicuous. Each scale on the back sometimes with black spot at base. The population of Okinawa Is. seems to have a red spot at posterior rim of operculum. Vertical fins red with brighter margin. Paired fins pink.

Distribution. —East Indies to southern Japan.

Remarks. —In the Museum National d'Histoire Naturelle in Paris are kept two specimens of different species both labeled as the types of L. genivittatiis. Of the two specimens the specimen MNHN9074 must be the holotype because of its identity with the original description and figure. It is very likely that the other specimen MNHN9075 is the holotype of L. geniguttatus because the types for the two species were caught by Peron at the same time, one individual for each.

Although L. genivittatus should have the priority over L. haematopterus, the latter name is adopted here because the present writer has hesitated to give it up. It is well established and seems more suitable than the former name which is little known and is only based on a single specimen without locality.

The two specimens of British Museum indicated as the type of L. richardsonii (BMNH 1851. 12. 27. 45) also belong to different species from each other. The larger specimen (98 mm standard length) agrees better with the original description and is here designated as the lectotype.
