Fig. 57. 
Scales of the lateral line about 70° in number , weak , unarmed; scales of the body smooth at the margin. Mar- 
ginal plates of the dorsal fin-groove 24 or 25 in number , smooth, with the posterior spinous point only slightly 
erected. Bays of the anterior dorsal fin smooth' 1 . Length of the head to the point of the opercular flap from 
25 to 27 % of that of the body. Length of the snout in young specimens less, in old specimens more, than 1 / 2 
that of the head. Breadth of the interorbital space, which is slightly concave e , about l / 5 or 1 / 6 / and the diameter 
of the eye about 20 %, of the length of the head 3 . Pectoral fins longer than the head 11 , with blackish, or bluish 
membrane on the outside and white or red rays, on the inside black, edged with blue or ( usually only during 
youth) brownish-red with an oval, black spot, dotted with milk-white spots (var. poeciloptera). Upper part of 
the body red.

c We have found the number of the tubiform ducts of the lateral line to be either 69 or 72. 
d In exceptional cases Tillier (1. c.) has found a few tubercles at the base of the anterior margin of the first ray. 
e More so in young specimens. 
7 From Y 6 to Y 21 the length of the head to the tip of the lower opercular spine, according to Steindachner. According to our 
measurements varying between 15 % (in young specimens) and 22 % (in old) of the length of the head to the point of the opercular flap. 
g According to our measurements and those of Prof. Malm, varying between 22 or 20 % (in specimens from 160 to 250 mm. long) 
and 19 or 18 % (in specimens from 250 to 550 mm. long) of the length of the head. 
h From 28 to 30 °/ of the length of the body, and with the tip always extending beyond the middle of the body when they are 
folded; also longer than the base of either the second dorsal or the anal fin. 
i Sometimes 15, sometimes 18, according to Steindachner and Tillier. 
1 (1+8 + 2) + 3, according to Steindachner. Sometimes 9 or 12 + 3, according to Collett.
