OsTRACIONTIDjE. 



Ostracion gibbosus. The fishes of this family are all called 

 "coffer" or "trunk" fishes, owing to the rigid box-like case 

 they are enclosed in. The specimen examined came from India. 

 There is no external evidence to show the sites of the sacculi. 

 The ear-labyrinth each side is contained and reposes in two 

 cavities inside the skull, whence it was picked out by forceps 

 without any cutting. The sagitta and asteriscus in one, and the 

 lapillus inside the " recessus utriculi " in the other cavity 

 (fig. VI., 10). 



Ostracion nasus. The observations made for this specimen 

 are similar to those for the previous one.
