TWO-SPOTTED SUCKER.

A mile or two eastward of Babbicombe and Petit Tor, in from ten to

fifteen fathoms water, there lies a stretch of flat stony bottom,

reaching away from the island known as the Ore Stone, towards the

mouth of the river Exe. This is a bit of ground to which a boatman

whom I occasionally employ often resorts with the dredge, and rarely

or never without a fair harvest of curious and interesting creatures.

Among other things he brings me from time to time numerous specimens

of what Yarrell calls the Bimaculated Sucker;[86] the propriety of

which name will be evident the moment you examine one of these little

fishes alive. Cuvier named the group in which they are found (a group

comprising very few species) _Discoboles_, because the ventral pair

of fins are united so as to form a circular disk or saucer, by means

of which the fishes have the power of adhering firmly to any solid

object larger than the circumference of the disk. Yarrell substitutes

the term _Cyclopteridæ_ for the family group; the name _Cyclopterus_,

used for the principal genus, expressing the same thing, that the fins

are united in a circular fashion. The word _bimaculatus_, signifying

two-spotted, alludes to two remarkable and conspicuous oval spots of

dark purplish brown or red, situated one on each side of the body, just

behind the pectoral fin. These spots, being comparatively large, and

separated from the general colour of the body by a well-defined white

ring, constitute a very striking and beautiful feature in these little

fishes.
