had fallen into his hands, rendering it likely that the species is limited to 

 particular districts. I have received several from Mr. Carrington, F.L.S., taken at 

 Guernsey : one of which is figured life-size. 



In Ireland one example 2| inches long has been captured at Connemara on 

 the west coast.

Length of head 2f to 3^, of caudal fin 6|, height of body 6 to 8 in the total 

 length. Eyes — 6|- diameters in the length of the head, 1 j to I3 diameters from the 

 end of the snout, and 1-j- apart. The posterior nostril close to the eye and patent, 

 the anterior more tubular. Greatest width of the head 2/3 its length. Body 

 widest anteriorly, flattened below, snout depressed, spatulate. Upper jaw the 

 longer, the posterior extremity of the maxilla reaches to beneath the middle of 

 the orbit. Teeth — a single row along the lateral ramus of either jaw, those in the 

 lower being rather widely separated : a patch of villif orm teeth anteriorly. Fins 

 — the dorsal commences about midway between the posterior extremity of the 

 head and the end of the caudal fin, posteriorly it is not continued nearly to the 

 caudal. The lower rays of the pectoral are not conjoined to those of the ventral. 

 Anal commences on a line somewhat posterior to the origin of the dorsal, and 

 does not reach nearly so far posteriorly as to the base of the caudal, which is 

 rounded or wedge-shaped. The suctorial disc is very similar to that already 

 described under L. Gouanii. Colours — reddish, tinged with orange, some reddish 

 bands on the head in a V-shape pointing backwards. A black, or dark purple, 

 light-edged ocellus just behind the end of the pectoral fin. Body somewhat 

 banded, as is also the caudal fin. 



Varieties. — The black ocellus on the side of the body has been observed to be 

 sometimes absent, especially in the young. Its colours are subject to great
