Figure 4A. — The round otoconia of Ha niotta raleighana are very smooth compared with the otoconia of other 

 chimaeras. An unusual rod-shaped crystal occurs in association with the otoconia which has a single (small closed 

 arrow) and twinned (large closed arrow) form. In the higher magnification section the rod shaped crystals show 

 further recrystallization on their surfaces. Bar = 10 (xm. 



Figure 4B. — Crystalhne aggregates of the rod-shaped crystal (open arrow) and apparent aragonite spindles 

 (closed arrows) are found in association with the typical aragonite spherule type crystals. Bar = 50 jim.
