JORDAN AND THOMPSON: FISHES OBTAINED IN JAPAN IN 1911. 225 
dorsal surface of head and line of back dark; belly in males coarsely pigmented, 
with colored area sharply limited above, extending over ventral surface of head and 
along base of anal; dorsal with black along middle of membrane, but with the rays 
uncolored, and pattern frequently obscured by a general heavy pigmentation; anal 
narrowly margined with black, otherwise as dorsal; ventrals black, pectorals and 
caudal dusky; in many cases fins entirely colorless; peritoneum silvery with black 
reticulations. 
This species may be distinguished from others by the absence of strongly 
marked lateral bands, the long barbels, the number of fin-rays, smooth pharyngeal 
teeth, proportions of the fin-bases and the measurements of the caudal peduncle. 
The specimens described were recorded as Acheilognathus lanceolata by Jordan and 
Fowler. From this species it is differentiated by the possession of one less divided 
ray in both the dorsal and anal fins, by the longer barbel, and by the greater average 
depth of the caudal peduncle.

Acheilognathus limbata Jordan & Fowler, Proc. U. 8. N. Mus., X XVI, 1903, p. 818, in part. Specimens 
from Morioka, on the Kitakama River, and some specimens from Lake Biwa, at Matsubara. 
Among the specimens recorded from Morioka by Jordan and Fowler as 
Acheilognathus limbata is a species which appears to be new. The type is in the 
collection of Stanford University. Cotypes are in the Carnegie Museum. 
Description of the type, 95 mm. in total length and 75 mm. in length to base 
of the caudal. 
Head 4 in body-length; depth of body 2.86; D. III, 9; A. II, 8; thirty-seven 
scales in lateral line, in transverse series between vertical fins 6/5; pharyngeal 
teeth 5-5. 
Tip of premaxillaries at level of, or slightly below, lower edge of pupil; snout 
slightly overhanging premaxillaries; mouth not very oblique; gill-rakers 2+12, of 
equal length throughout; pharyngeal teeth smooth, with a narrow grinding surface 
and hooked tip; lateral line complete; barbel a quarter of diameter of eye in length, 
or less, somewhat coarse in texture; depth of caudal peduncle 2 in length of head, 
its length 1.14 in same, or 4.5 in body-length. 
Dorsal inserted midway between tip of snout and base of caudal; its base 1.25 
in head; its length 1.5; anal inserted under last dorsal ray, its base 1.7 in head, its 
height the same, first branched ray extending beyond base of last; margin of fin some- 
what faleate; ventrals under dorsal insertion, their length equal to anal height; that 
of pectorals slightly greater. 
A blue-black lateral stripe along sides of caudal, its width over half as wide as
