27. Rhinichthys bowersi Goldsborough & Clark, new species. 
Head 3.87 in length; depth 4.65; eye5 in head; snout 2.6; maxillary 3; interorbital 3; preorbital 
4.4: dorsal 8; anal 7; scales 1048-7, 25 before dorsal. 
Rhinichthys bowersi, new species. 
Body moderately elongate, little compressed; caudal peduncle long and stout, slightly compressed, 
its least depth 2.1 in head; head blunt, somewhat flattened above; snout projecting, the profile above 
and behind eye slightly concave; mouth horizontal, inferior, its cleft not quite reaching orbit; the 
fleshy snout projecting beyond mouth; premaxillary not protractile, joined to the snout by a rather 
broad and distinct frenum; lower lip rather thin; tongue fleshy, joined to mouth; a well-developed 
barbel at tip of maxillary; eye somewhat anterior, high; gill-membranes broadly joined to isthmus. 
Teeth usually 4-4, sometimes 1, 44, 1; bluntly hooked and with slight grinding surface. Origin of 
dorsal midway between tip of snout and base of caudal, slightly posterior to origin of ventral, its longest 
ray 1.4in head, base 2 in head and covering about 8 or 9 rows of scales, its margin nearly straight; caudal 
emarginate, lobes equal and rounded; anal similar to dorsal, its origin about 3 scales posterior to last 
ray of dorsal, its longest ray 1.6 in head, its base 2.5; ventrals short and rounded, 1.6 in head, reaching 
vent; pectoral short and broadly rounded, longest ray 1.35 in head, tip not reaching base of ventral by 
a distance 1.5 times greater than eye. 
Scales nearly uniform on entire body, not crowded before dorsal, about as long as deep; head entirely 
naked; alimentary canal short, not as long as body; peritoneum dusky, with dark specks. 
Color in spirits uniform olivaceous, belly somewhat lighter, fins all plain. 
This species appears to be intermediate in some respects between Rhinichthys and Hybopsis. In 
form of mouth it resembles Rhinichthys cataractey, but in general form and appearance of body it 
resembles Hybopsis kentuckiensis. The scales are too large for any known species of Rhinichthys, and 
the teeth are not those of typical Rhinichthys, being 1, 4-4, 1 or 4-4.
