500 TEN YEAES IN SWEDEN. 



4 in. The males are always larger than the females. 

 They live in a state of monogamy, and an actual pairing 

 is said to take place between the two sexes ; spawn in 

 March ; colour blackish grey ; edges of fins red ; all the 

 rays covered with thick skin. ;D. 11; P. 28; A. 9 ; 

 C. 11. 



Tolerably common in some parts of the Baltic (but 

 never on its Swedish shores), the Cattegat and the North 

 Sea, to far up on the coast of Finland. A specimen 16 in. 

 long will be 8 in. deep and 4 in. wide. 



Gen. Liparis, Art. 



Smaller fish ; one dorsal fin ; body smooth ; in form like 

 the black goby. 



54. LIPAEIS BAKBATUS, Ekst. Storre Lumpfisk. The Sea 



Snail. F. D. 



Nilsson remarks that these fish seem to be identical with 

 the lumpsucker in a lower stage of development, and he can 

 see no other generic difference between a full-grown liparis 

 montagui and a young cyclopterus lumpus, which has not 

 yet obtained its knotty skin, than that the former has one, 

 the latter two dorsal fins. 



This species is larger than the next, measuring 7 to 8 in., 

 whereas Montague's sucker rarely exceeds 3 in. The prin- 

 cipal difference is in the shape of the pectorals, and the 

 length of the dorsal and anal fins. In the sea snail they both 

 are joined to the square tail one-third of its length. In 

 Montague's sucker the last ray of the dorsal does not reach 

 to the root of the tail-fin, but the anal fin is joined to the 

 pointed tail. Colour reddish grey, covered with broad irre- 

 gular black spots. Is rare on the Scandinavian coasts, and 

 has hitherto been taken only in the Baltic off the shores of 

 Stockholm and (Ester Gothland. D. 35; A. 27; P. 27;
