K0.1266. LABROID FISHES OF JAPAN— JORDAN AND SNYDER. 639 
Head 4 in length; depth 4; depth of caudal peduncle T; eye 4^ in 
head; snout 2f ; interorbital space 4^; D. IX, 12; A. HI 12; scales in 
lateral series 25, between lateral line and insertion of dorsal 2, between 
latarel line and insertion of anal 8. 
This species is characterized by its slender body, high and flexible 
dorsal spines and the small ninnber of dorsal and anal raj^s. Canines 
very small, scarcely difl'erentiated, f. Scales before dorsal small, 
crossing the median line in about 8 rows. 
Longest dorsal spine 2 in head, very slender; longest ray 2^. Anal 
spines short, slender, the second about equal to diameter of eye; long- 
est ray 2i in head. Caudal rounded. Outer ray of ventral filamentous, 
longer than the pectoral, at least in the male. 
Color in spirits brownish, shaded with blue, an indelinite light band 
extending along side of bod}^; head with two dark bands, one below 
exQ, the other above, occasionally one or both are very indistinct or 
absent; a small l>lack blotch at upper edge of base of pectoral; dorsal 
broadly bordered with brownish, the border growing wider anteriorly, 
where it is almost black, the base of lin with a row of large round light 
spots, which in some specimens are united to form a band; caudal dark, 
the dorsal and ventral edge light; anal with three broad longitudinal 
bands, separated by very light lines, the basal band dark, the outer 
ones slighter; ventrals and pectorals plain. 
The female is unknown to us. Of 24 specimens about 150 millime- 
ters long from 6 localities all are males. It is possible that Jlalichmres 
tenulsjnnis (Giinther), with the black on the dorsal restricted to a single 
spot and the ventrals not filamentous and shorter than the pectorals, 
may prove to be the same species. 
This species is general!}' common throughout southern Japan, and 
may be recognized b}' the height and slenderness of the dorsal spines 
and the dark color of the fins. 
Our specimens are from Tokyo, Misaki, Kobe, Onomichi, Hiroshima, 
and Nagasaki.

31. HALICHCERES TREMEBUNDUS Jordan and Snyder, new species. 
Head SyV in length; depth 4^; depth of caudal peduncle Yi; eye 4^ 
in head; interorbital space 4; snout 2f ; D. IX, 12; A. Ill, 12; scales 
in lateral series 25; between lateral line and insertion of dorsal 1 or 2; 
between lateral line and insertion of anal 9. 
Body elongate, compressed, dorsal outline not elevated, upper anterior 
profile evenly curved from tip of snout to origin of dorsal fin, the 
caudal peduncle deep. Head pointed, snout sharp, the jaws equal. 
Teeth in a single series laterally, closely apposed but not coalesced, 
growing gradually larger toward tip of snout, the anterior canines not 
much enlarged, f, a few minute teeth behind the canines; a small
