y Gonorhynchus abbreviatus Schlegel (Fauna Japonica). 



The measurements of Gonorhynchus abbreviatus Schlegel, are placed along- 

 side the others. There seems very little of a distinctive character except 

 the longer pelvics. The number of scales in a longitudinal series is 165. 

 The dark extremities of the fins seem to be deeper in colour, while the caudal 

 has a black spot on each lobe. 



Synodus synodus (Linnseus). 

 Saurus synodus Cuv. & Val. 



Depth of body 4| to 5f in the length ; length of head 3 to 34. Snout 

 li to If as long as diameter of eye, which is 5i to G-J in length of head; 

 interorbita! width 7.} to SJ-. Upper jaw projects slightly, Prrumaxillary 

 If to li in length of head. Teeth in both jaws in a double row, lanceolate, 

 and with a tendency to arrow-shape. Teeth alternately long and short, 

 especially in upper jaw. Palatine teeth much more slender and in several 

 rows ; inner rows longer, anterior teeth largest. Tongue covered with 

 retrorse teeth. 



Top of head striated ; the striations few and very pronounced. Supra- 

 orbital bones prominent and slightly striated. 



Gill rakers reduced to rows of minute teeth. 



Dorsal 14-15. Origin of dorsal just behind base of pelvic. 



Dorsal fin equidistant from tip of snout and root of caudal ; fourth ray 

 the longest, 21 in length of head. First dorsal ray two-thirds length of the 

 fourth; subsequent rays diminish in length. Adipose very small. Distance 

 from adipose to root of caudal three-fifths distance from adipose to base of 

 dorsal. Anal 9-10. Length of base half the length of dorsal base. 

 Pectorals 2i in length of head. Pelvics eight-rayed ; sixth ray the longest, 

 which is seven-tenths length of head. Caudal forked. 



60 to 62 scales in a longitudinal series ; 5 between origin of dorsal and 

 lateral line.
