PISCES. 
The interesting Pteraspidee, concerning the character of which 
there has been so much controversy, and which were long held to 
be sponges, have been found so near Plymouth as the Rame Head. 
‘‘ Scales of fish,” from blocks lying on the beach at Mount Batten, 
were exhibited at the meeting of the British Association in 1841. 
Fish-scales have likewise been found at Plymstock. When first 
discovered at the Whitsands, the Pteraspide were deemed fucoids, 
and were lost sight of until Mr. Pengelly found them at Rame. 
Mr. Bellamy states that a fossil fish was found in the rocks 
(? slate) of Jennycliff Bay.
