-LUIS species is found in Cornwall. I also 

 discovered it in the Sound of Jura. 



Its length is about four inches ; the skin with- Descrip- 

 out scales, slippery, and of a dusky color, occa- 

 sionally spotted ; the body taper ; the nose 

 grows slenderer from the head, and ends round ; 

 the teeth small ; before each eye are two small 

 filaments united at their base ; behind the eyes 

 are two circular ocellated spots, sometimes blue, 

 but varying in color, and not perceptible in 

 young fish. In the middle of the back is an 

 oval mark formed by small dots, of a whitish 

 color. The dorsal fin lies near the tail, and 

 consists of eleven rays; the anal is placed 

 opposite, and has nine rays ; the tail is round- 

 ed ; the ventral fins have four rays, joined by 

 an intervening membrane with an oval depres- 

 sion in the middle; beyond that is another 

 strong membrane with a similar depression. 

 By means of these instruments it adheres to 

 stones or rocks.
