164 Mr. J. Y. Johnson on rare and little-known 



parative lengths of the bases of the two divisions of the fin are 

 as 19 to 9. Each spine carries a short filament, and the last 

 spine is rather longer than its neighbours. The fin is truncate 

 behind, with the angle rounded off. 



The pectoral fins are inserted close to the edge of the opercle; 

 they are rounded, and their length to the total length of the fish 

 is as 1 to 5^. The ventral fins are in length rather more than 

 one-seventh of the total length of the fish, and are inserted con- 

 siderably behind the pectoral fins. The spine is rather more 

 than half as long as the first soft ray. There is a long scale-like, 

 appendage between their roots. The vent is in front of the 

 middle of the fish by about one-thirteenth of the whole length. 

 The anal fin rises from a groove ; it is about half as long as the 

 dorsal fin, and their terminations are opposite each other. The 

 spinous portion is lower than the rest ; and the spines gradually 

 increase in length backwards. The fin is truncate behind. The 

 tail is high and compressed; its fin is truncate, with the angles 

 somewhat rounded off. 



The following measurements are taken from a specimen which 

 had a total length of 6| inches, and a height of 2 inches.
