REMARKS. 



The above Cyprajae are natives of the warmer regions of the globe, and of course are seldom 

 met with either near the Arctic or Antarctic Circles. There does not seem at present to be 

 found much variety either in species or colour of those which are found in the Northern Seas, 

 which is one reason, perhaps, why the catalogue of these latter has been little attended to 

 by Naturalists. Those which are found upon the coasts and in the seas of Europe, are also 

 much smaller than the above.
