PLATE XVI. 



Fig. 



1. Detached anterior median dorsal plate of Asterolepis maxima. 



2. Posterior median dorsal plate from which the surface has flaked off behind and 



on the right side. 



3. Right anterior dorso-lateral plate ; the anterior border is not quite perfect, 



as it does not show the peculiar processes for articulation with the external 

 occipital. 



4. Right posterior dorso-lateral plate. 



5. Median ventral plate ; a small but very perfect specimen. 



All these figures are of the natural size.
