BRITISH MUSEUM (NATURAL HISTORY). 
Plates III.-V. 
The fish-fauna of the Upper Lias has hitherto been most 
exhaustively studied in Germany and France. Although the cliffs 
in the neighbourhood of Whitby have continually yielded numerous 
specimens of fossil fishes since the days when Young and Bird'" first 
identified petrified "pikes" {Lepidotus semiserratus, Agassiz) these have 
received only superficial notice in comparison with the corresponding 
fossils from the Upper Lias of Wiirtemberg, Bavaria, and France. 
Five species from Whitby were briefly described and several 
others named by Agassiz in his great work on fossil fishes, half a 
century agot ; SimpsonJ and Egerton|| each subsequently recognised 
an additional species ; in 1876 Blake § published a list of the fauna 
without making any additions, contributing only brief notes and 
unsatisfactory figures of two species ; still more recently the present 
writer has described Gyrosteus mirabilis^ and recorded the occur- 
rence of Pholidophorus germanicus.'''' Li Germany, on the other 
hand, Quenstedtff and WagnerJJ have published much more extended
