BULLETIN OF THE BUREAU OF FISHERIES 
contents of the body cavity removed. With a sharp scalpel the flesh was cut from 
one side, exposing the vertebrae which were scraped clean and counted. 
The complete list of data taken is as follows: 
Measurements: 
From the tip of the closed mandible to — 
The posterior end of the opercle, designated as the “head length. ” 
The insertion of the dorsal fin. 
The insertion of the anal fin. 
Where the silvery epidermis of the body ends, more or less truncately, on the sides of the 
caudal peduncle, this measurement designated as “body length.” 
The ends of the caudal rays when the edges of the caudal fin are held parallel to the body 
axis, thus securing what is here called the “total length.” 
Counts: 
Vertebrae, excluding the hypural. 
Unbranched and branched dorsal rays. 
Unbranched and branched anal rays. 
Weights: 
Total. 
With the entire contents of the body cavity removed, designated as the “cleaned weight.” 
Gonads. 
Other observations: 
The state of maturity of tlfe gonads. 
Age, from sample of scales taken from the side under the insertion of the dorsal fin. 
The head lengths and the distances to the insertions of the fins were expressed 
in all computations as percentages of the body length, these percentages being cal- 
culated with sufficient accuracy by means of a slide rule.
