Length of head 4^-, of caudal fin 7, height of body 7-}± in the total length. 

 Tjije — diameters 4 to 4^ in the length of the head, 1 diameter from the end of the 

 snout, and 1 apart. The greatest height of the head rather exceeds one half of 

 its length. Barbels — three, two on the snout and one beneath the 'symphysis of 

 the lower jaw. Teeth — cardiform in the jaws with an outer enlarged row of 

 widely separated ones in the lower jaw, and in a patch on the vomer : none upon 

 palatines or tongue. Fins — the first dorsal commences above the middle of the 

 opercle and extends to above the last third of the pectoral fin, the length of its 

 base equals 2/3 of that of the head. Vent situated at 1/3 of the distance between 

 the front edge of the eye and the posterior extremity of the caudal fin. Colours — ■ 

 bi'ownish becoming lighter on the sides and beneath : the smaller example shows 

 traces of what may have been cross-bands. 



This species, instituted from young examples, is very similar to M. cimbria, but 

 deficient in one of the barbels as well as possessing an excess of about 5 dorsal and 

 11 anal rays. 



Habitat. — One example is 3 inches in length taken at eighty fathoms depth, 

 the other nearly 4^ inches long, and figured life size, captured at a similar depth 

 between Shetland and Faroe.
