Halichoeres nigrescens (Schneider).
Four examples, 130 to 166 mm. "Check violet green. Predorsal violet. Upper apple green blotch on opercle, posteriorly and little lower metallic blue blotch; vermilion below and on lower part of opercle pale apple green. Throat pale pink. Around black pupil pink ring, then green ring and outer pink ring. Scales on body margined with blue, violet, emerald green or white; medially each vermilion yellow or dull green, Dorsal with upper half pink, lower half apple green.
Anal basally green, terminally purple blue. Caudal yellowish green basally, each hind corner yellow margined against general vermilion colour of fin by oblique white linc above and below."
Agrees best with Bleeker's figure (Atlas Ich. Ind. Veerland., vol. 1, 1862, p. 37, fig. 4).
Halichoeres trimaculatus (Quoy and Gaimard). Ho, Yui2.

Two examples, 81 to 89 mm, Green and scarlet." Vertical fins all bright orange in alcohol, and paired fins tinged with orange. These specimens are generally of a light brown colour, but do not show any scales on the upper part of the opercle as in Bleeker's figure of Guntheria trimaculata. He also shows a dark blotch on the trunk above the pectoral, not present in my material. Morita's painting, as published by Jordan and Seale, of H. trimaculatus does not show any black spot either at the origin of the pectoral or the upper rays of the caudal basally.
Duymaeria flagellifera (Valenciennes).
Sau Gnar, Yi'. (—teeth coat).
Shek, Pan1 (Stone), Sau3
Eleven examples, 100 to 138 mm., in poor preservation.
Thalassoma lunare (Linnaeus).
One example, 125 mm.
Hemipteronotus pentadactylus (Linnaeus),
One example, 143 mm.
CALLIOYMIDAE.
Synchiropus ornatus new species. Sin3 Yui" (Fan fish).

Snout 41/10 to 47/8 in head; eye 5 to 6%, orbit 4% to 43, subequal to little greater than snout, over 2 times bony interorbital; maxillary reaches nearly or quite to front of orbit, length 4 to 54 in head; teeth villiform, in bands in jaws, none on palate or tongue; interorbital 6 1/5 to 67% in head, nar- rowly concave; preopercle spine strong, bent up, with 2 small antrose spinules on its upper edge. Cranium behind eyes with radiating striae behind each eye above.

D. IV 8,
I, spines flexible, third 11/5 to 12/5 in head, last ray 1% to 1; A. 7, 1, last ray 1 1/5 to 13; least depth of caudal peduncle 4 to 42/5; caudal 2 1/5 to 24/5 in rest of body; pectoral 3% to 3%; ventral 2 to 3 1/5.
Drab to mars brown or broccoli brown above, with 5 variable dark or neutral black cross blotches. Whole back with variable small pale gray to whitish blotches, larger and more crowded on sides where dark lines form reticulations. Scattered gray white spots on side of head. Spinous dorsal pale gray brown, with variable white spots or blotches, also scattered dark or blackish spots and large black, white edged ocellus on last mem- brane. Soft dorsal with diffuse blackish spots or blotches, also some scat- tered whitish blotches or bars, most conspicuous posteriorly on fin. Anal neutral black terminally and whitish basally, in former area submarginal gray white line on each membrane and another parallel submedianly on fin. Caudal gray brown, with 2 neutral black blotches above and lower submarginal blackish band; upper half of fin otherwise with blue white or gray spots or bars and lower half of fin with similar coloured lines on membranes. Pectoral whitish, with grayish blotches on each ray. Ventral with white or blue white horizontal lines on pale gray basal membrane, lower margin of fin white, rest of fin neutral blackish. Under surface of body cream white, neutral gray shade on breast.
Type, 53456 A.N.S.P. Saukiwan, Hong Kong, 1930. Length 133 mm. Also 53457 A.N.S.P., paratype, same data, 95 mm.
Diagnosis. Related to the genotype Callionymus lateralis Richardson (Zool. Voy. Sulphur, Fish, 1844, p. 65, pl. 37, figs. 5-6) described without locality other than Pacific Ocean from a specimen about 98 mm. long. This has a somewhat similar general colour pattern, though the first dorsal is entirely different and the caudal lacks the black lower submarginal band. Day (Fishes of India, pt. 2, 1876, p. 323) has placed Richardson's species as a questionable synonym of Callionymus lineolatus Valenciennes, with which it apparently does not belong.
Callionymus splendidus Herre (Philippine Journ. Sci., vol. 32, No. 3, 1927, p. 416, pl. 2, Bungau) is based on a specimen but 45 mm. long. It suggests the present species somewhat in shape of the head though described with the small circular gill opening below and a little posterior to the origin of lateral line." The long filamentous first dorsal spine reaches the base of last dorsal ray. (Ornatus, ornamented).
ELEOTRIDAE.
Bostrychus sinensis Lacépède. Vvu' (Dark).
Four examples, 108 to 118 mm.
Valenciennea muralis (Valenciennes). Fa1 Um1 (Flower —).
Two examples, 78 to 81 mm.
Differs a little from McCulloch and Ogilby's figure (Rec. Austral. Mus., vol. 12, no. 10, July 14, 1919, pl. 37, fig. 4) in that the 2 lower red longitudinal bands are both continued out over the caulal to its hind edge. They also have fewer horizontal dark bands on the spinous dorsal.
