Among the .aberrant forms which lie upon the outskirts of 

 the families of Sharks and Skates without bearing a very 

 close resemblance to either, is the Linnrean genus Chimcsra, 

 which, although consisting of no more than two recognised 

 species, has been separated into two distinct genera; and that 

 one which particularly comes under our notice is among the 

 most remarkable of fishes, whether we consider its shape and 

 habits, or the coldness of the climate in which it finds its 

 safety and delight. The far greater number of the species in 

 the families above named, are inhabitants of the warm or 

 temperate regions of the ocean; but the Chimera and its 

 kindred species the Callorhynchus, frequent the coldest por- 

 tions of the globe; but what is still more extraordinary, 

 these closely-allied fishes are known only in regions wide as 

 the poles asunder. 



It is the Chimncra, or to call it by its humbler and more
