SYSTEMATIC CATALOGUE OF, FISHES.' 103 



abruptly decurved; mouth small, horizontal, lower jaw included, upper jaw not extending to 

 orbit; barbel shorter than pupil; eye large, .33 length of head, placed high on side of head; 

 teeth, 4 — 4; lateral line straight; scales, 40 to 47 in lateral series, 11 in crosswise series, 16 to 18 

 before dorsal fin; dorsal large, 8 rays; anal small, 7 rays; caudal well forked. Color: back 

 mottled green, sides silvery with bluish lateral band widened into dusky spots; dusky band 

 through eyes and snout; fins unmarked. Length, 4 inches, (dissimilis, dissimilar.) 



Ranges from Lake Erie to Iowa and Arkansas, southward to the headwaters 

 of the Tennessee in North Carohna. Not rare in Swannanoa River at Asheville 

 and in Spring Creek at Hot Springs, where highly colored specimens, with very 

 distinct blue-black spots on back and sides, were collected by Jordan in 1888. 



92. HYBOPSIS LABROSUS (Cope). 

 Thick-lipped Minnow. 



Ceralichthys labrosus Cope, 18706, 458; Catawba River, in Macdowell and Burke counties, N. C. 

 Hybopsis labrosus, Jordan, 18896, 134, 138; Yadkin River and Pacollet River, S. C, tributary of Santee Jor- 

 dan & Evermann, 1896, 319. 



Diagnosis. — Body slender, depth less than head and contained 5.5 times in total length; 

 head contained 4 to 4.5 times in total length, top gently decurved to snout; mouth horizontal, 

 slightly inferior, lips thick, maxillary extending as far as margin of orbit; eye contained 3.33 to 

 3.75 times in head and slightly less than interorbital space; teeth 1,4 — 4,1; barbels longer than 

 in any other species, more than half diameter of eye; scales closely imbricated, 34 to 40 in 

 lateral line, 8 to 10 in transverse line, 16 in front of dorsal; fins small; dorsal rays 8^ length of 

 first ray equal to half distance from fin to anterior edge of pupil, dorsal inserted over ventrals; 

 anal rays 7 or 8: caudal deeply forked, peduncle long and slender. Color: males dark blue 

 above, with black markings on back; a dark lateral streak, and a small round black spot on 

 caudal base; in large examples, a dark patch on posterior rays of dorsal; females silvery, with 

 pale blue streak along sides of peduncle; males in spring with fins red and head and neck 

 covered with tubercles, Length, 3 inches, (labrosus, thick-lipped.) 



Cope, in his original account of this species, said it was not uncommon on the 

 bottom in clear and rapid creeks which flow into the upper waters of Catawba 

 River, in the counties of jVIacdowell and Burke. Jordan found the species com- 

 mon in Yadkin River near Salisbury. The fish resembles Phenacobius inhsivlng 

 thick lips, and may be further recognized by the long barbels. 



93. HYBOPSIS HYPSINOTUS (Cope). 

 High-backed Minnow. 



Ceralichthys hypsinotus Cope, 18706, 4.58; Catawba and Yadkin rivers. 



Hybopsis hypsinotus, Jordan, 18896, 138; Pacollet River, S. C, tributary of the Santee. Jordan & Evermann 

 1896. 320. 



Diagnosis. — Form stout, robust, compressed, depth contained 3.75 times in total length; 

 head short, broad, flat, its length equal to body depth; muzzle not prominent, mouth inferior, 

 horizontal; maxillary extending to margin of orbit; lips thin; barbels small; eye contained 3.5 

 times in length of head and once in interorbital space; line of back rises gradually to first dorsal 

 ray, then descends abruptly, so that base of fin is oblique, the fin margin vertical, the posterior 

 ray less than half length of anterior; dorsal fin placed in advance of ventrals, its rays 8; anal 

 rays 8; teeth 1,4 — 4,1; scales, 38 to 41 in lateral line, 4 or 5 above lateral line and 3 below. 

 Color: silvery, with a double series of black specks along lateral line and a blackish lateral band; 

 a dark line around snout between eyes; in breeding males, fins bright red, body with violet 

 luster. Length, 3 inches, {hypsinotus, high-backed.)
