ON THE LOCATION OF THE SACCULUS AND ITS 

 CONTAINED OTOLITHS IN FISHES. 



By Colonel C. E. Shephekd (Indian Army). 



In continuation of the article under the above heading that 

 terminated in vol. xviii. (1914) p. 146, of the 'Zoologist,' fresh 

 material has come to hand of interesting but not generally 

 accessible fishes. The information gathered is now published to 

 bring all the available knowledge on the subject up to date. 

 Additional illustrations of otoliths, alluded to in the former 

 paper, are also given.

Acipenser strurio (the Sturgeon). Illustrated fig. VII. The 

 otoconie in place of a solid lapillus, and in conjunction with the 

 other stones seems to be a connecting-link, in the case of otoliths, 

 between the cartilaginous and teleostean fishes.
