Cottus
a genus of fishes, by some made the type of a family Cottidæ, by others placed under the Triglidæ or Gurnards. The head is large, depressed, furnished with spines or tubercles; there are teeth in front of the vomer and in both jaws; there are two dorsal fins; the anal fin is small; the body is without scales. Yarrell enumerates four species:
C. gobio, the River Bullhead, Miller's Thumb, or Tommy Logge; C. scorpius, the Sea Scorpion or Short-spined Cottus; C. bubalis, the Father Lasher or Longspined Cottus; and C. quadricornis, the Four-horned Cottus. In this country species called indifferently bullhead and there are several representatives of the catfish.
