JORDAN AND THOMPSON: FISHES OBTAINED IN JAPAN IN 1911. 229 



three-fifths length of third; outhne 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 

 a narrower dusky band parallel to margin of fin; other fins without visible pattern. 



The males of this species are apparently slenderer than the females with a 

 depth shghtly 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. 



Key to Japanese species of Acanthorhodeus. 

 a. Lateral band broad as pupil, not pointed posteriorly; lateral line completely absent; no large spot 



on dorsal alremius. 



aa. Lateral band very narrow, less than half width of pupil; lateral line present in first four scales; a large 

 black spot anteriorly on dorsal sciosemus. 



58. Rhodeus kurumeus sp. nov. (Plate XXVI, 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. 6011a 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; 

 scales in lateral series 33 (32-35), in transverse series, 11, between occiput and 

 fifteenth dorsal.
