Rather plentiful. I find them in abundance, in pools left by the tide, or beneath stones at low water. Many of them exhibit some most beautiful markings.
Cottus quadricornis [The Four-horned Cottus].
I have never found this species but in the stomachs of other fish; which leads me to conclude that they generally inhabit deep water; or, at least, that they do not come so near the shore as the preceding species.
Aspidophorus Europæus [The Armed Bullhead].
This is another stomach species. But I have found these, also, though very sparingly, amongst the rocks at low tide.
Gasterosteus trachurus [The Rough-tailed, Three-spined Stickleback] and
Gasterosteus leiurus [The Smooth-tailed Stickleback] are both plentiful. The former along the coast, and the latter in our streams and rivulets.
Spinachia vulgaris [The Fifteen-spined Stickleback].
Common amongst the pools along the shore. I have seen this species with sixteen and seventeen spines. They are known amongst our fishermen by the very peculiar denomination of “Willie-wan-beard.”
Chrysophrys aurata [The Gilt-head].
