59 Part III. — Twenty -fourth Annual Report 



Nine examples of this Callionymus have their earstones represented on 

 pi. iii. b. The sizes of the fishes are, three at 150mm., 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. Discoboli. 



Genus Cyclopterus. 



Cyclopterus lumpus, Linn. The Lumpsucker. PI. iii. b., fig. 58 ; pi. v., 

 tig. 15. 



The earstones of the lumpsucker are exceedingly small when compared 

 with the size of the fish. In an example 15J inches long the earstones 

 measure only Wmm. 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. Gobiesocid^e. 



Genus Anarrhickas. 



Anarrhichas lupus, Linn. The Cat or Wolf-fish. PI. iii. b., figs. 40-43 ; 

 pi. v., fig 21. 



The earstones of the cat-fish are small in comparison with the size of the 

 fish. Those of a specimen 27J inches long measured about 4mm. in 

 length by about 2 -2mm. 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 2*7mm. long 

 by about l'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, 

 12 j inches and 13^ inches in length, are represented by figures 

 42 and 41. 



Fam. Blenniid^e. 

 Genus Pholis. 

 Pholis gunnellus, Linn. The Butter-fish. PL 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 4-h inches long 

 measured about 1mm. by '6mm.
