SUPPLEMENT 



Part of the material having been mislaid and not recovered until 

 the remainder of the manuscript was in type, it has obliged the writer 

 to bring in this portion as a supplementary item. Circumstances 

 have unfortunately deferred illustration of the new species. 



Including these additions the total number of species obtained from 

 the two dredgings, omitting pelagic forms, is 400. This includes 5 

 species of Brachiopoda, 41 Pelecypoda, 14 Scaphopoda, and 340 Gas- 

 tropoda. Of these 93 species were found at both stations, 196 only 

 off Fernandina, and 98 only off Georgia. 



Out of the whole number of species collected (400) 240 appear to 

 be new, including the 6 scaphopods described by Mr. J. B. Hender- 

 son, jr.
