ART, 2. FORMOSA AND PHILIPPINES FISHES—-FOWLER AND BEAN. 71 
Color in alcohol pale avellaneous generally. Back and upper sur- 
face of head with many darker or brownish vermiculations, usually 
formed by pale apical spot on each scale. Along middle of side 
three obscure dusky blotches, first about middle of pectoral, second 
below soft dorsal, and third at caudal base. Fins all pale generally. 
Spinous dorsal with rather broad dusky to blackish streaks or 
blotches, little more inclined than spines. Soft dorsal with three to 
four rows of deep dusky rounded spots and fin edge dusky. Caudal 
similar. Anal whitish, edge dusky. Ventral pale. Eye pale brown- 
ish, pupil dusky, with metallic green luster. 
Length, 91 mm. Takao, Formosa. 
We give the above account as our example differs in a number of 
respects from a series of Japanese examples in the Academy. Also, 
the species does not appear to ever have been recorded from Formosa. 
In profile the Formosan example has a greatly obtuse muzzle with 
even jaws. In the Japanese examples the lower jaw of all strongly 
projects. In the Formosan example the spinous dorsal has dark ver- 
tical bands, whereas in the Japanese they are black spots like those 
on the soft dorsal, and in some cases the apical form horizontal 
bands. In all other respects the color pattern is such as may evolve 
from that of the Japanese examples, to that of the Formosan, as a 
change with age. This is also true of the pores on the cheek. In 
none of our examples do they resemble those in the figure by Jordan 
and Snyder for Ctenogobius gymnauchen.° In our Formosan ex- 
ample we believe much of the contrast in color pattern has faded 
during preservation. 
RHINOGOBIUS CANDIDIUS (Regan). 
Head, 2% to 8; depth, 44 to 53; D. VI—, 8; A. 9; scales, 32 to 34 
from gill-opening above to caudal base; 10 scales transversely be- 
tween soft dorsal and anal origins; snout, 2% to 3% in head; eye, 32 
to 44; maxillary, 24 to 24; interorbital, 74 to 84. Tongue more or 
less convex in front. Gill-opening forward about opposite last 
fourth in head or to hind preopercle edge. Scales with 16 to 18 
nearly parallel striae medio basally, apical denticles 23 to 25 in single 
row and circuli rather coarse. Maxillary variable, sometimes to eye 
front and again to its center. Color in alcohol largely dull brown- 
ish. Spinous dorsal with blackish basally, usually forward, and soft 
dorsal dusky medially. Often obsolete dark vertical bar at caudal 
base. Both soft and spinous dorsal edges pale. Length, 33 to 45 mm. 
Eight from Lake Candidius, Formosa. October 10, 1907. 
Our examples usually have the predorsal naked, though in some it 
is more or less scaly.
