JORDAN AND THOMPSON: FISHES OBTAINED IN JAPAN IN 1911. 229 
three-fifths length of third; outline of fin straight; anal similar in all respects, its 
insertion under fourth branched ray of dorsal; first branched ray barely reaching 
base of last one; pectorals 1.33 in head, just reaching base of ventral, latter four- 
fifths length of pectorals, and not reaching insertion of anal. 
Lateral line present in first four scales, series continuing, dropping sharply 
from fourth towards ventral line of body. 
A blue-black lateral stripe, half as wide as pupil, beginning three or four scales 
from last scales on caudal base and continued to within eight scales of angle of gill- 
opening, broadest part above anal base; shoulder-spot behind angle of gill-opening 
present in males only, represented in females by an occasional dusky area; in males 
very definite, square, as large as pupil, followed by a similar silvery area and a 
subsequent dark blotch; line of back darkest just before dorsals; belly in males 
pigmented as usual; dorsal with a prominent, definite blue-black spot somewhat 
triangular, its tip at base of fifth branched ray, its base as wide as pupil and half- 
way up second spiny ray; this spot being apparently the anterior portion of a broad 
stripe which is posteriorly indistinct; distally to this the fin is white having distad 
anarrower dusky band parallel tomargin of fin; other fins without visible pattern. 
The males of this species are apparently slenderer than the females with a 
depth slightly more than two and one-half times in the body-length; the anal 
narrowly edged with black; a broader and more vivid lateral stripe and shoulder- 
spots. The belly is pigmented as usual. In one specimen the spot on the dorsal 
is lacking.

58. Rhodeus kurumeus sp. nov. (Plate X XVI, fig. 2). 
Described from numerous specimens collected in the Chikugo River at Kurume 
in Kiusiu by Jordan and Snyder in 1900, the longest female 5 cm. in total length, 
the longest male 5.3 cm., both breeding, the females frequently with eggs partly 
extruded through the ovipositor. A male in the Stanford collection is taken as the 
type; No. 601la Carnegie Museum is the cotype. 
Head 3.83 in body-length; depth 2.75; snout 4 in head; eye 3.2; length of 
caudal peduncle from last anal rays 1.5 in head, its depth 2.125; dorsal height 1.4; 
dorsal base 3.4 in body-length; anal height 1.33 in head; its base nearly equal to 
head; dorsal rays II, 10 (or 11); anal rays II, 10 (or 11); pharyngeal teeth 5-5; 
seales in lateral series 33 (32-35), in transverse series, 11, between occiput and 
fifteenth dorsal.
