JORDAN AND THOMPSON: FISHES OBTAINED IN JAPAN IN 1911. Pea 
Depth 2.3 in body-length to last vertebra, D. III, 8; A. II, 10 or 11; seales in 
lateral line 33, in transverse series between insertions of dorsal and anal 6/4; 
pharyngeal teeth 5-5. 
Head 4 in body-length; eye 3.12 in head, snout 4, with tubercles in breeding 
males; gill-rakers short, 2+7; pharyngeal teeth smooth, not plicate, hooked, with 
narrow grinding surface, without color; caudal peduncle strongly tapering, its 
length 1.3 in head, its depth 2; lateral line complete; barbel long, slightly shorter 
than snout. 
Dorsal inserted nearer base of caudal than tip of snout, distance from snout 
to first ray 1.66 in body; dorsal base slightly less than four-fifths of length of head, 
its height 1.5 in head; anal inserted under second branched ray of dorsal, its base 
equal to that of dorsal; its height 2 in head, its margin straight; ventrals inserted 
before dorsal, their length slightly greater than anal height; pectorals 1.3 in head. 
Color plain, without stripes or spots on body, although as a whole darker than 
usual and with the line of the back very dark; dorsal margined narrowly with black; 
a broad band of white below the margin as wide as pupil, the lower part so shaded 
as to form an indistinct dark band below the white; anal dusky, similar to the dorsal, 
but stripes less distinct, margin straight; ventrals and pectorals clear; peritoneum 
black. 
This species is easily distinguished from all others of its genus in Japan by its 
greater depth, plain coloration, and fewer number of scales in the lateral line.

This species is here described from very numerous specimens, adult and young, 
from Lake Biwa, at Matsubara, in part the collection of Dr. Jordan in 1911, and in 
part specimens previously recorded from that locality by earlier authors and now in 
the collection of Stanford University. They are the originals of Acheilognathus 
lanceolata Jordan and Fowler.
