Color brownish olive with 5 or 6 dusky blotches on sides, one being at base of caudal; all fins dusky, except some- times the ventrals; a black blotch on posterior part of spinous dorsal, a more or less brownish or dusky blotch in front of base of pectorals; all soft fins vertically barred; one or two dusky bars downward and backward from eye. This species is most closely related to klamathensis, but is a heavier fish, the eye is larger, the head not so pointed, and the dorsal is inserted slightly more posteriorly.

Known only from Fall River, where it is associated with Cottus gulosus and Cottus asperrima, but more common than either. Here described from 19 specimens from Fall River at Dana, col- lected by Rutter and Chamberlain, the largest specimen being inches long. Named with refer- ence to the large eyes. Type no. 58499, U.
