fin and the lower lateral line. One lateral line on the right 

 side. Scales between tlie lateral lines perfectly smooth ; those 

 between the outer lateral lines and vertical fins, and those on 

 the head, strongly ctenoid ; scales of the blind side smooth. 

 Two nostrils — one between the eyes, the other opposite to the 

 lower margin of the lower eye. Eyes extremely small, the 

 upper not in advance of the lower ; interorbital space much 

 wider than the orbit. The length of the snout is two fifths of 

 that of the head. Angle of the mouth conspicuously nearer 

 to the end of the snout than to the hind margin of the gill- 

 cover, below the eye. Tail not much elongate. The height 

 of the body is two sevenths of the total length (without 

 caudal), the length of the head one fifth. Leftside uniform 

 brown ; vertical fins with a white edge. Three distant round 

 blackish spots on the lateral line of the left side may be acci- 

 dental in this specimen. 



One specimen from Chefoo, 18 inches long.
