I present preliminary data describing two new forms within the Cottus carolinae species-complex from the Ozark Highlands, the eyelash sculpin and the fringe-head sculpin. The eyelash and fringe-head sculpins can be diagnosed from all other species of Cottus by cirri (thin fleshy appendages), a character heretofore unknown in the genus. The eyelash sculpin can be further diagnosed by a few cirri above the eye and the fringe-head sculpin by a large number of cirri on the head and elsewhere. In addition, I provide data on pectoral fin ray number in the C. carolinae species-complex that validates the recognition of the Black River race in the Ozark Highlands (18-19 in Black River race, 13-17 in all other C. carolinae). The distribution of Ozark Highland members of the C. carolinae species-complex and a new size record are also discussed.
