cover the differences between L. richardsonii Giinther and L. hsema- 

 topterus Bleeker. The sharpness of the lateral teeth, size of the eye, 

 and height of the dorsal spines are all age marks. Kner ^ is prob- 

 ably right in calling these one species. 



This fish is rather common in southern Japan. We saw it in 

 Nagasaki.

Description after Bleeker, in the absence of a well-preserved speci- 

 men. 



Head 3 in body, 4 in total length; depth 2f in body, 3| in total 

 length; eye 3 in head; interorbital space 4; D. X, 9 or 10; A. Ill, 8 

 or 9; scales in lateral line 48; in transverse series 6/16 or 17. 



Breadth of body 2| in its depth; head somewhat acute, its height 

 equal to its depth; upper profile of head somewhat convex before 

 eyes, slightly concave on snout; nostrils distant, anterior tubular, 

 valved; snout little longer than eye; suborbital breadth a little 

 less than eye diameter; jaws equal, maxillary ending before the 

 eye, 3 in head; lower jaw 2| to 2^ in head. Teeth in jaws in many 

 series in front, laterally and posteriorly in one row; two curved 

 canines in front of both jaws, moderate in size in npper, small in lower 

 jaw; lateral series of about 12 teeth, anteriorly conical, acute or 

 obtuse, posteriorly rounded molars. Lips fleshy; opercular spine 

 indistinct. 



Dorsal spines moderately stiff, middle ones longest 3 in depth of 

 body; dorsal rays a little higher; pectorals longer than ventrals, a 

 little shorter than head; anal spines moderate, second and third 

 subequal, shorter than first ray, soft fin a little longer than high, con- 

 vex, angulated posteriorly. Caudal moderately emarginate, lobes 

 acute, slightly shorter than head. 



Color of body above olivaceous, below golden; iris yellow or red- 

 dish; fins reddish or yellow. Our young specimen shows a distinct 

 blotch between the pectoral and lateral line. 



Bleeker remarks that this is distinguished from the true lisermito'p- 

 terus by one more row of scales above the lateral line and by the 

 rounded molars of the jaws, which, he says, are diff'erent in fishes of
