aun Part I11.—Twenty-fourth Annual Report 
Nine examples of this Callionymus have their earstones represented on 
pl. ui. B. The sizes of the fishes are, three at 1OOmm., one at 130mm., 
two at 112mm., one at 100mm., and two at 80mm. Their earstones 
closely resemble those of Callionymus lyra both in shape and size, except 
that in one or two of them the anterior end is rather more distinctly 
notched. 
Fam. DiscoBo.i. 
Genus Cyclopterus. 
Cyclopterus lumpus, Linn. The Lumpsucker. PI. iii. B., fig. 58; pl. v., 
fig. 15. | 
The earstones of the lumpsucker are exceedingly small when compared 
with the size of the fish, In an example 154 inches long the earstones 
measure only 1-4mm., in length by about 1mm. in depth, or about one 
two-hundred-and-eightieth part of the length of the fish. They are 
subrotund in form, but one side is straight or nearly so, while the other 
is boldly arcuate or gibbous. Both ends are rounded, but one of them, 
where it joins the nearly straight lateral margin, is moderately angular, as 
shown by the enlarged photograph (fig. 15, pi. v.). 
Fam. GOBIESOCIDA. 
Genus Anarrhichas. 
Anarrhichas lupus, Linn. The Cat or Wolf-fish. PI. iii. B., figs. 40-48 ; 
pl wae 21. 
The earstones of the cat-fish are small in comparison with the size of the 
fish. Those of a specimen 274 inches long measured about 4mm. in 
length by about 22mm. in depth, so that these earstones are only about 
the one hundred and seventy-fourth part of the length of the fish. They 
have a somewhat rugged appearance, resembling a rudely formed arrow- 
head, being broadest and thickest at the (%) posterior end, then tapering 
to a sharp point at the opposite extremity. The earstones of a fish 12 
inches long did not differ greatly in shape from those of the larger 
example, but were considerably smaller, being only about 27mm. long 
by about 1'6mm. in depth (see fig. 43). They were proportionally 
rather larger than those of the larger fish, but small compared with those 
of the Gadoids. The earstones of other two examples of Anarrhichas, 
123 inches and 134 inches in length, are represented by figures 
42 and 41. 
Fam. BLENNIID2. 
Genus Pholis. 
Pholis gunnellus, Linn. The Butter-fish. PI. iii. B., figs. 38 and 39. 
The earstones of the butter-fish are also very small. They are of an 
oval shape, but neither in form nor sculpture is there anything very 
characteristic about them. Those obtained from a fish 44 inches long 
measured about 1mm. by ‘6mm.
