MARINE INVERTEBRATE ANIMALS. 



The following account of the Marine Invertebrate Animals, inhabiting those parts 

 of the Arctic Ocean visited in the course of our late expedition, is very incomplete 

 owing to nearly the whole collection having been necessarily abandoned with the 

 Victory. Some few, however, of those that were considered to be most interesting, as 

 fomiing the types of new genera, were brought by us to England, and specimens of 

 each have been deposited in the valuable museum of the Royal College of Surgeons. 



The arrangement and generic characters adopted in this notice, is that of Latreille in 



tlie last edition of Cuvier's " Regne Animal."
