dusky; anal light brown, spotted with darker brown and milky white.

MARCGRAVIA Jordan. 
282. Marcgravia diemensis (Le Sueur). Guecguan. 
(Cottus grunniens Linnus, “habitat in America,’’ dorsal 11-26, anal 22, is Opsanus taw or Marcgravia cryptocentra, and 
can not be identified with any Asiatic fish.)

eye; nose somewhat less than eye, 4.50 in head; maxillary 2 in head, reaching a vertical from behind 
eye; opercular spines 4; three fringed tentacles above each eye; a fringe of small cirri on each side of upper 
lip, and a similar fringe encircling lower jaw; other smaller cirri on top of head and along margin of 
preopercle; dorsal m-19; anal 14; pectoral 1.4 in head; ventral 1.4; teeth in coarse villiform (molar- 
like) bands in jaws and on yomer and palatines. 
Color brown, coarsely mottled, and speckled with darker; fins barred. Life color, dark, mottled with 
black, dark brown and gray, the gray forming three broken and irregular bands; belly, throat, and chin 
flesh color; pectoral strongly banded with gray and brown; a black band at base of caudal followed by 
five gray and four brown bands. 
A single specimen, 3 inches long, from Cuyo. 
This species is type of the genus Coryzichthys Ogilby, named but not defined in the Report of the 
Amateur Fishermen’s Association of Queensland, 1907, p. 11. 
Family CALLIONYMIDA. 
SYNCHIROPUS Gill. 
283. Synchiropus ocellatus (Pallas). 
Head 3.30 in length without caudal; depth 5; depth of caudal peduncle 3 in head; width of head 
1.16 in its length; eye 4 in head; nose 3.75; interorbital space equal to width of pupil; mouth very 
small, its width less than eye, the jaws subequal, the maxillary touching a vertical from anterior margin 
of orbit; jaws with minute teeth; preopercular spine with two curved hooks, directed obliquely inward, 
gill-opening as wide as pupil, superior, situated on the.neck nearly midway between the preopercular 
spine and the base of the spinous dorsal; dorsal 1y-8; anal 7; pectoral 1.3 in head, reaching past front of 
anal; ventral equal to head; caudal 1.16; lateral line complete, high, its course about an eye-width 
distant from the mid-dorsal line. 
Color in spirits: Upper parts and sides brown; sides of head with numerous small ocelli (pale- 
encircled dark dots); sides of trunk marbled with grayish, the lighter color crossing the back in six crenu- 
late-edged bands; lower part of side with about four roundish gray spots, each with smaller whitish specks 
about its circumference; other similar smaller white specks forming an indefinite row along outer edge 
of belly; middle of sides, between the marblings, with many small dark-encircled pale specks, of same size 
as the facial ocelli; spinous dorsal with three incomplete double-edged oblique crossbands, above which, 
between the first and third spines, is arow of four roundish ocellate black spots, each with a darker center 
and a pale edge; soft dorsal with two or three indistinct obliquish bands; caudal barred with dusky near 
base, pale submedially; its outer half obscurely double-barred, its posterior margin pale; anal dusky, paler 
near base, the rays tipped with whitish, ventrals twice barred broadly with blackish, tips pale; pec- 
torals with three bands of small black spots inthe rays; breast crossed by a vague, diffuse band of dusky; 
belly pale. 
Two specimens, 1.50 and 2 inches long, from Calayan, in tide pools. On the life color, Mr. McGregor 
has the following note: ‘‘Brown, mottled with gray; tail with a few red spots; pectoral and ventral 
more or less orange; first dorsal with four conspicuous ocellate brown ‘spots; snout and gill-covers and 
sides of face thickly speckled with blue.”’ 
Giinther’s Callionymus microps, the figure of which shows the spinous dorsal uniform black without 
ocelli, does not appear to differ in any important respects from the present species. The pectoral fins 
have fine, dark cross bars. Synchiropus lili Jordan & Seale, recently described from Samoa, is also
