THE ZOOLOGIST. 



ing this paper has been prepared most carefully to give an idea 

 of the varied markings and the indentations on the edges of 

 these stones. The small black illustrations represent the actual 

 size of the asteriscus nest to it. It will be readily seen that it is 

 only by making a magnified drawing that these various markings 

 and the indentations of the edges can be appreciated. The 

 following tabulated form shows the family and the fish from 

 which the different asterisci in the Plate were taken ; only some 

 of those fishes having a fair-sized asteriscus are given, as many 

 an asteriscus, e. g. t those of the smaller Blennies and Gobies, 

 is so minute as to be as small, or even smaller, than any full 

 stop in this page of print. Rather more of the asterisci of the 

 " Gyprinida" or Carp family, have been shown than of other 

 families, as their asterisci differ from those in other Teleosteans 

 very materially in being the largest of the three otoliths in each 

 side of the skull.*
