eye to front of dorsal rising in a gentle curve; depth of caudal peduncle 2 in head; eye lateral, = bony 
interorbital, 2 in snout from tip of lower jaw; maxillary reaching to below center of pupil; least 
width of preorbital 0.6 of eye; teeth in rather wide bands in each jaw, an outer series of enlarged 
teeth in each; vomer and palatines toothless; entire head, except jaws, scaled; fourth and fifth dorsal 
spines longest, a little less than 2 in head; membrane from last spine reaching to front of second 
dorsal fin; sixth soft ray longest, a little greater than 2 in head; A. i— 8, length of base only 0.8 that of 
soft dorsal; pectoral rounded, median rays 1.5 in head; third and fourth rays of ventral longest, 2 in 
head; space between ventrals 0.6 of eye; branchiostegals 6; gillrakers very short. 
Color in alcohol, brown, paler below; vertical fins spotted with small dusky brown spots, a 
dusky brown spot on upper part of base of pectoral. Large specimens 6 inches in length are plain 
dark brown, with the fins dusky. Small specimens, the size of the type, are much paler especially 
along the sides of the body and head. Several dusky brown bands radiating backward from eye; 
side of body with small dusky brown spots. Still smaller specimens (2 inches long) are much paler, 
side of body mottled with dark brown, and side and lower part of head punctate with minute dusky 
spots; vertical fins pale with distinct dark crossbars. 
One fresh specimen was olivaceous with 6 dark bands over the body. A spine on angle of pre- 
operculum directed downward and forward. 
I obtained examples, 1.5 to 9 inches in length, in fresh-water streams and in salt water along shore 
and in marshes about Honolulu, and some at Hilo. Two examples are in Dr. Wood’s collection, and 
7 were obtained by the Albatross in 1896 from Honolulu.

scales 25-7; least depth of caudal peduncle 2 in head; depth of base of pectoral 2.3; teeth in upper jaw 
in a band, outer row enlarged, others small, villiform; teeth of lower jaw similar to those in upper, 
but no enlarged teeth in back part of sides of jaw; lower pharyngeals with the lower ends triangularly 
expanded, having villiform teeth; third dorsal- spine filamentously prolonged, reaching to base of third 
ray of second dorsal; second dorsal spine longest of rest, 1.6 in head; posterior dorsal rays increasing

fourth ray of ventral longest; inner very slender, unbranched; dorsal profile of head and body a little 
more convex than the ventral; upper profile of head sloping upward at angle of about 45° from snout 
to front of first dorsal, gently rounded, descending in gentle curve to posterior end of base of second 
dorsal; upper profile of caudal peduncle straight, horizontal; mouth but little oblique, lower profile 
with less inclination than upper, mouth on level of lower third of pectoral fin; ventral profile of body 
very gently and regularly curved from base of ventrals to base of caudal fin; greatest depth of body at 
front of first dorsal; interorbital very narrow, width less than half diameter of pupil; entire head and 
body scaled except interorbital, top and sides of snout and jaws; scales all large, those of head scarcely 
smaller than those of body; scales below eye cycloid, the rest ctenoid; preorbital narrow, less than 
diameter of pupil; body somewhat compressed, width of head 1.75 in length, widest part of body very 
slightly narrower than head. 
Color in alcohol, body faded, general color brown, about 6 unequally defined, dusky, vertical bars 
on side back of pectoral, a similar band over nape midway between eyes and front of first dorsal 
spine; traces of pale blue spots on side; dorsal and anal fins dusky, other fins pale. 
Color in life (field No. 221)., uniform dark with rows of minute blue dots. 
Many specimens were obtained at Honolulu, where it is abundant.
