 On the other hand, an apparently incomplete dra^ving, made from a 

 single fish, like that in the ' Fauna Japonica,' does not afford sufficient 

 authority as to the form of the single rays. "With regard to the different 

 coloration, the larger specimen of the two iu the British Museum is 

 nearly unifonn, although much darker than the figure of the Japanese 

 fish ; the other exhibits verj' distinctly the variegated coloration given 

 by Sir J. Eichardson. Thus, not having other materials than Sir 

 John Richardson had, I do not think myself justified in separating 

 the following specimens from the species of the ' Fauna Japonica.'
