150 CLASS XIV. 



specimens of this fish are described under the name of Cydopterus minutus 

 PALL., SpicU. Zool. vn. Tab. 3, figs. 79, and Golius minutus, Zool. 

 Danic. See THOMPSON Annals of not. Hist. in. 1839, pp. 38 43. This 

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

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

 Liparis L., Liparis barbatus EKSTROEM, NOZEMAN Uitgez. Verhandel. I. 

 bl. 581, PI. ix. figs. 3, 4, BLOCK IcTith. Tab. 123, figs. 3, 4, with a single/ 

 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 AKTEDI, which has also been adopted by many mo- 

 dern writers. 



Lepadogaster GoUAN. Pectoral fins large, descending below 

 the throat, supported by 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. Rays of branchiostegous membrane five or four. 

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

 none.

A genus scarcely distinct from the preceding, and imperfectly 

 described by LACEPEDE. Maxillary teeth conical, the anterior 

 rather large. Ventral disc single, formed anteriorly by the united 

 pectoral fins, posteriorly by the ventrals. 



Sp. Lepadogaster dentex, Cyclopterus dentex PALL., Spic. Zool. Fasc. vn. 

 Tab. I., Cuv. R. Ani., 6d. ill., Poiss. PI. 108, fig. i ; the specimens in the

IV. Ventral fins thoracic, narrow, contiguous at the base. 

 Four perfect branchiae. Head flat above, with an oval disc trans- 

 versely costate. (Naucratoidei.)

 subulate, crowded, in palate towards the back part very small, 

 passing gradually into a roughness scarcely to be distinguished.
