FISHES. 563 



131. MOTELLA TRICIRRATA, Nilss. Tretommad Skarlanga. 



The Tliree Bearded Eockling. 



Two beards on the nose, one under the chin ; body 

 strewed with large round blackish spots ; usual length 

 12 to 16 in. 



Never met with in the Cattegat, but occasionally on the 

 west coast of Norway in rather deep water, on stony bottom. 

 Spawns early in spring. 



132. M. CIMBRIA, Struss. Fyrtommad Skar Langa. The 



Four Bearded Kockling. D. 



Three beards on the nose, one under the chin ; tail 

 pointed, rounded off; colour yellow-brown, with small 

 black spots, and is easily distinguished at a glance from 

 any of the others, by the greater length of the first fila- 

 ment in the anterior dorsal fin, which in a fish of 10 in. 

 will measure above 2 in. The usual length here is 

 12 in. 



Is occasionally, but rarely, taken in the Oresund, and 

 off the west coast of Norway. 



133. M. MUSTELA, Jenn. Fern Tommad Skar Langa. The 



Five Bearded Eockling. D. 



Four beards on the nose, and one on the chin ; colour 

 yellow-brown, unspotted; the lateral line distinctly 

 marked by a series of short slender white streaks. 

 About the size of the last ; appears to be the commonest 

 and widest spread of all the genus on these coasts, and is 

 taken on the Gothenburg Skargard, as well as along the 

 west coasts of Norway. 



Head compressed, colour tinged with a silvery gloss. 



134. M. ARGENTEOLA, Yarr. Silfver Fargad Skar Langa. 



The Mackerel Midge. 



This beautiful little fish, which rarely exceeds 2 in. 

 in length, much resembles the whiting in form and 

 proportions, but may always be known by the silvery 

 colour, and five barbules, four on the head. It much 

 resembles the young of the last, but as Mr. Yarrell ob^
