NO. 1-4 1. aoiUOIl) FISHES OF JAPAN— JOItDAN AXD SXYDER. 39 
Chin with a large, median, flat barbel, al)out as long a.s the diameter 
of eye, followed l)v 3 minute ones which are concealed when the large 
one is depressed. Nostrils without tubes. 
Head naked. Body with minute, cycloid, parti}' embedded scales; 
smaller and farther apart anteriorly; larger and more close together 
post(M'i(>rly. The scales appear to the unaided eye like shallow depres- 
sions in the skin. 
Dorsals separate; the spines slender and flexible; the first 5 close 
together and evenly spaced; the sixth far removed; the distance 
l)etween its base and that of the sixth about equal to the space occu- 
pied 1>y the first 5; the last spine when depressed reaching insertion 
of soft dorsal. Anal inserted l)elow the fourth or fifth ray of dorsal; 
the rays when depressed extending a little farther posteriori}' than 
those of dorsal; neither reaching base of caudal. Caudal long; the 
upper and lower rays with long, ribbon-like filaments. Ventrals long; 
divided to the base; ra^'s I, ^; the spine slender. 
Color in spirits, whitish; growing brownish above; a narrow light 
band on posterior part of liody, running from a point a little a])ove 
insertion of dorsal, backward and upward to near middle of base of 
caudal; body l^elow the band yellowish white; eye with a slightly 
oblique silvery ])and a))out as wide as the or])it. Dorsal fins somewhat 
dusk}'; center of caudal dusky; upper and lower parts lighter; upper 
filaments pearly white; the lower ones dusky; anal light, with a nar- 
now, pearly band at base; pectoral with an indistinct, crescent-shaped 
light mark near its base. 
In life the upper parts are l)luish, becoming green on upper part of 
head with a shade of violet below the green; a reddish ])lotch at base 
of pectoral; lateral l>and above anal, brick red; the l)and extending on 
the caudal, where the reddish color ])ecomes diffused over the fin al)ove 
and ])elow. Spinous dorsal light l)lue, with a tinge of pink; violet at 
l)ase, becoming greenish aV)ove; 2 indistinct, narrow, l)lue lines run- 
ning horizontally near upper edge of fin; caudal bluish, tinged with 
red; the filaments greenish; pectorals and vt^ntrals with l)luish and 
greenish tints. 
The upper edge of the dorsal fins is damaged, so that the height of 
the rays can not l)e determined. The tips of the pectoral rays are 
broken ofl'. The upper edge of the fins shows no trace of filaments.
