 them, like more scrupulous feeders, to starve in the midst of plenty, while the prodigious 

 swarms they bring forth have enabled them to offer a wholesome banquet to the monsters 

 of the deep without any injurious diminution of their ow^n numbers. The following list 

 exhibits the species which have a more or less doubtful claim to have come from a depth 

 greater than 300 fathoms. It is interesting to notice, that in the thirty-one specimens 

 of Gammarina reported from these vast depths, twenty-five genera are represented, of 

 which ten are new, and twenty-eight species, of which twenty-six are new.
