specimens of this fish are described under the name of Cyclopterus mlnutus 

 Pall., Spicil. Zool. vii. Tab. 3, figs. 7 — 9, and Gobius mlnutus, Zool.

 species has two dorsal fins, of which the first is ahnost entirely hidden in 

 the thick skin. It occurs in the North Sea, as does another, Cyclopterus 

 Liparis L., Liparis iarbatus Ekstroem, Nozeman Uitgez. Verkandel. i. 

 bl. 581, PI. IX. figs. 3, 4, Bloch Ichth. Tab. 123, figs. 3, 4, with a smgle 

 dorsal fin, which is very long, extends close to the caudal fin, and has thirty 

 rays, of which the first thirteen are not jointed. On this species is founded 

 the genus Liparis of Artedi, which has also been adopted by many mo- 

 dern writers. 



Lepadogaster GouAN. Pectoral fins large, descending below 

 the throat, supported bj four firmer rays at the lower part on each 

 side, united around an oval disc in front of the concave disc of 

 the ventral fins. Rajs of branchiostegous membrane five or four. 

 Dorsal fin single, remote, opposite to anal. Pyloric appendages 

 none.
