476 TEN YEARS IN SWEDEN. 



Widigren's list of fish in Lulea Lapland. Said to spawn 

 late in November or December, but the season is probably 

 regulated by the age of the fish. 



16. C. TEICUSPIS, Reinh. Tagg Grenig Simpa. F. 



Resembles the father lasher much in shape and colour, 

 but is smaller ; the head shorter ; the body more elon- 

 gated ; preopercle with four spines, the longest of which 

 has two points. The lateral line is soft, and there is a 

 difference in the fin ray formula. No teeth on the 

 vomer. Length 8 in. to 9 in. D. 11^16; P. 18; 

 V. 1,3; A. 18. 



Specimens of a coitus exactly agreeing with the 0. tricus- 

 pisj Reinh., have been taken by Liljeborg near the North 

 Cape, and the Finnish specimens are mentioned by Malm- 

 gren as coming from the shores of the White Sea. 



17. C. QUADEICOENIS, Cuv. Horn Simpa. The Four-horned 



Cottus. F. 



In appearance more resembles the last than any other 

 of the family, for it is more slender and elongated than 

 the father lasher ; but it may easily be distinguished from 

 either by the four large tubercles on the top of the head 

 and the rough warts on the sides of the body. D. 8 

 14; P. 17; Y. 1,3; A. 14; C. 11. 



Is principally confined to the middle and north of the 

 Baltic, and as far as Lulea Lapland, where they go far 

 up into rivers. Attains a length of 8 in. Is also met with 

 in Lake Ladoga, Finland. There is a smaller variety, rarely 

 more than 6 in., met with in the Lake Wetter, in Sweden, 

 in which the tubercles are smaller and more blunt, the warts 

 on the body fewer, and the eyes larger. Spawns in Decem- 

 ber and January. 



In all this genus the male may be known from the female 

 by its more slender shape and longer fins. The anus lies in 

 the foremost half of the body ; the ventrals, when laid back, 

 reach to the anus, and the dorsal fin beyond the root of the 

 tail. In the female the abdomen is more protuberant, the
