THE AQUARIUM BULLETIN 



having tirst extended all the hn rays 

 as shown in I-'igure 1. One of these 

 photogra])hs should he ])aged in our 

 "Fish note-book," in the place where 

 the history of the striped bass is to be 

 entered. This account should tirst set 

 forth where the specimen was pur- 

 chased and where it was taken. 

 liHiuiry should be made as to its 

 abundance and range, as well as to 

 its relative value as a food fish. 

 Alention may be made of the other 

 kinds of fish to be found in the market 

 when this bass was purchased, esi)ec- 



may note its form, weight, and i)ro- 

 portions, and to what extent any of 

 these may vary one way or another. 

 Sexual variation must likewise be 

 commented upon, and record must be 

 made of what is known of its breeding 

 habits and young. Following this 

 should appear the coloration of the 

 specimen, given in systematic detail, 

 with markings and any peculiar ap- 

 ])endages. 



We now commence at the ce])halic 

 or head end of the fish, and mention 

 any peculiarities of the "mouth-

 same time and on the same fishing 

 grounds, or otherwise. Brief notes 

 upon its natural history may next be 

 entered; these may either form per- 

 sonal observation ; taken from author- 

 itative text-books, or gathered from 

 the fishermen — from such of them as 

 are good observers, and truthful as to 

 statement of fact. A few lines may 

 be devoted to the place of this bass 

 in the system, or its classification, 

 naming at the same time some of its 

 allies or near congeners. Next, we

 the part of the dentary (d) or maxil- 

 lary (/;/), following the account with 

 similar ones on the eye (e), the oper-

 The form of the abdomen (a) should 

 also be noted, as it varies in many 

 species of fishes. 



All the fins of the various kinds of 

 fishes all over the world vary in many 

 l)articulars, in the most remarkable 

 manner, with respect to their number, 

 their form, their modification, their 

 color, the number of rays and spines
