but compressed, although narrower than in Sicyases ; those species, 

 therefore, agree bettor with Gobieso.v, Laccp., m. C. Jimhriata has 

 not been examined by myself, and, therefore, I am not justified in 

 removing it from CotyVis.

The upper and lower jaws with numerous small fringes. Teeth 

 of the anterior series conical, and nearly equal in size ; several other 

 small ones behind these, in both jaws.

Tj-pical specimens in the Berlin Museum. Form of the head and 

 body as in Gobiesox nudus. The diameter of the eye is one-fourth 

 of the width of the interorbital space. The anterior nostril with a 

 small tentacle. The poiut in which the opercular apparatus termi- 

 nates is not moveable. Lateral line none. The dorsal is little 

 longer than the anal. 



I subjoin to this genus, for the present, the following species, 

 known only from Steller's and Pallas's descriptions : — 



a. Cydoptenis ventricosus, Pall. 



Cycloptems ventricosus, Pall. Sincil. vii. p. 15. t. 2 ; Cuv. JR^gne Aniin- 

 Lepadogaster ventricosus, Bl. Schn. p. 3.

Pallas drew up his description from the MS. left by Steller and a 

 dried specimen presei-ved in the St. Petersburg Museum. 



The body is smooth and soft, somewhat flat superiorly and very 

 thick, whilst the tail is suddenly narrowed behind the vent. The 

 head is flat and obtuse, with the cleft of the mouth directed upwards, 

 and with the lower jaw longest, if the mouth is open. Jaws with 

 minute, rather obtuse, unequal teeth, the interior ones being the 

 largest in the lower jaw. Nostrils double, above the eyes. Eyes 

 directed upwards, but on the side of the head. The giU-opening is 

 reduced to a foramen, above the pectoral, covered by a cutaneous 

 production of the gill-cover. Branchiostegals about four. Pectorals 

 large, extending to below the throat, with eighteen or twenty rays. 

 The ventral disk is said to be ovate, entire, with six distinct rays on 

 each side, siuTounded by a very broad cutaneous margin. The 

 dorsal fin is very near the caudal, — the sixth of the rays, which are 

 of black colour, beiug the longest. The anal is situated opposite the 

 dorsal, at a considerable distance from the vent ; the rays are 

 simple, or very indistinctly bifid ; the fifth is the longest. The anal 

 papilla is nearer to the anal fin than to the ventral disk. Caudal 

 ten-rayed, subtruncated, the rays being branched. 



Steller describes the kidneys as commencing near the skull ; double 

 anteriorly, tLey are united into one mass posteriorly. Two ureters
