al (45.0 mm standard length) with a slender, elongated axis extending posteriorly, and 10 

 primary lamellae. 



Body elongate, round in cross section. Maximum depth of body 16% of standard length. 

 Caudal peduncle short and high, its length 25%, its depth 43% of standard length. 

 Pectoral fin fan-like, sharper in female than in male, 13-16 fin rays, 14 or 15 rays in most 

 specimens studied. Pelvic fin originates in advance of dorsal fin origin; prepelvic length 

 51% of standard length; rays usually eight, seven in two among 16 specimens counted. 

 Dorsal fin originates posteriorly to origin of pelvic fin, predorsal length 1 1 1 % of prepel- 

 vic length, with two procurrent rays and eight rays, rarely seven (two of the 16 specimens 

 counted). Anal fin originates under or slightly behind the insertion of dorsal fin; with two 

 procurrent rays eight, rarely seven (one among 16 specimens counted). Caudal fin shal- 

 lowly forked, lobes round; with 8-12 dorsal procurrent rays, 7-9 ventral procurrent rays, 

 19 (10+9) principal rays. 



Supratemporal canal short, without connection between the left and right ones, with six 

 pores. Otic canal, with six pores, connecting with infraorbital canal and body lateral line; 

 however, in a few specimens, no connection between otic canal and body lateral line pre- 

 sent. Supraorbital canal with 10 pores. Infraorbital canal without interruption, 14 pores. 

 Preopercular canal extending to middle portion of preopercle; with seven pores. Mandi- 

 bular canal with interruption, not connecting with preopercular canal, five pores. 

 Body lateral line extending from dorsal to gill cover, curving down to ventral lateral stripe, 

 and ending at position of middle of pectoral fin. Lateral line interrupted in a few places, 

 most with one or two interruptions. Lateral line pored scales about 17. 

 Pharyngeal bone short, posterior limb bent; pitted surface bearing two large, elongate fos- 

 sae; end of anterior limb bearing a notch. Pharyngeal teeth in one row, 5-5, 5-3, or 5-4; 

 teeth elongate, hooked at tip. Gill rakers 8, short. 

 Vertebrae 37-39; precaudal vertebrae 20-21, caudal vertebrae 17-18. 

 Intestine long, with complex coils; its length 135% of standard length. Anterior chamber 

 of the gas bladder short, 65% of posterior chamber in length. Pneumatic duct placed at 

 the constriction of the gas bladder. Peritoneum dark. 



Tuberculation. Tubercles present on whole body, including lateral, dorsal, and ventral 

 sides, dorsal and lateral sides of head, snout and chin. Each scale in 5-7 rows on breast 

 bearing a few tubercles at its apical margin. Scales on the ventral side other than the breast 

 scales bearing fewer tubercles than scales on sides. Each scale on the anterolateral body 

 bearing one or two rows of tubercles: one row near apical margin, and composed of two 

 or three tubercles; and another row close to center of scale, consisting of one to three tu- 

 bercles. Tuberculation of pectoral, pelvic, dorsal and anal fins similar to that in Phoxinus 

 cumberlandensis. No tubercles on caudal fin. 



Coloration. Two dark lateral stripes present on sides. Lower lateral stripe more deve- 

 loped than upper one, and extending from anterior end of snout, through eye, gill cover, 

 and along side to terminate in a black spot at caudal fin base. Stripe almost equal in width 

 throughout its length. Upper lateral stripe shorter than lower one, and interrupted into a 

 series of spots behind dorsal fin origin; or the whole stripe broken down to large speck-
