Table 8. — Frequency distribution of the ratio between the length of the body and the length of the head 

 (L/H) for each of the 11 species of Coregonidx in the Great Lakes 



[Numbers at the top of the columns indicate the classes of ratios; entries beneath these are the numbers of each form, by classes; 

 numbers in the last column give, for each group, the total numbers of specimens included in the table. The various species 

 in each lake often are divided into two size groups. The numbers expressing millimeters, given after the name of the lake, 

 indicate, when preceded by a plus (+) sign, the lower length limit of specimens of the group; when preceded by a minus (-) 

 sign, the upper length limit]
