' We have found tlie number of tin- tubifurm ibicts of the lateral line to be eiDier 09 or 7'2. 



'' In exceptional cases Tillier (1. c.) lias found a few tubercles at the base of the anterior margin of the first ray. 



' More so in young specimens. 



■f From '/b ^° V21 "^ ^'"^ length of the head to the tip of the lower opercular spine, according to Steindaciiner. According to our 

 measurements varying between 15 % (in young specimens) and 22 'i (in old) of the length of the head to the point of the opercular flap. 



' According to our measurements and those of Prof. Malm, varying between 22 or 20 % (in specimens from IGO to 250 mm. long) 

 and 19 or 18 % (in specimens from 250 to 550 mm. long) of the length of the head. 



'' From 28 to 30 % of the length of tlie body, and with the tip always extending beyond the middle of the body when tlicy arc 

 folded; also longer than the base of either the second dorsal or the anal fin. 



' Sometimes 15, sometimes 18, according to Steindachner and Tillier.
