List of Brachiopoda, Etc., from Falkland Islands. 



An account of the fossils brought home by Mr Bruce will 

 now be given ; and as they are in the form of hollow casts, 

 the descriptions are from impressions taken in wax, which 

 thus reproduce the forms of the original shells. 



The matrix of these fossils corresponds with the descrip-

 therefore, that both series of fossils are from the same bed. 

 On the other hand, the " Challenger " specimens, although so
