﻿434 SMITHSONIAN MISCELLANEOUS COLLECTIONS [VOL. 47 



of the Baltimore Geographic Society, and now by Mr. Bryant, has 

 been chiefly hurried collecting at as many localities as possible, 

 rather than the patient study of conditions and results, exhaustively 

 applied to any single locality. 



However, in any event, much must be left to the future, and every 

 addition to our knowledge is so much gained ; and fortunately for 

 science, if not for the easy-going inhabitants of the Bahamas, the 

 spread of agricultural operations and the introduction of domesti- 

 cated animals progresses so slowly that the natural conditions are 

 not, as in Hawaii, being radically changed before they can be thor- 

 oughly studied. 



Though somewhat hampered by illness Air. Bryant collected 

 energetically and in certain localities where time permitted very thor- 

 oughly. His journey included opportunities for observation in the 

 vicinity of the south bight of Andros Island especially at Mangrove 

 Cay ; at and about Nassau, New Providence ; at numerous points on 

 the east and north shores of the Abaco group, and a few points on 

 their south and west shores and at Riding Point, Grand Bahama, 

 opposite ; also some of the cays to the westward of Little Abaco. 



In a general way each group of islets, or each island inhabited 

 by land shells has its characteristic forms of pulmonate mollusks. 

 Some few forms are widely distributed, but others, especially Ccpolis 

 and Cerion, are for the most part very local, with a few widely dis- 

 tributed species. It is therefore very desirable that the fauna of each 

 island should be thoroughly elucidated. Of the species collected by 

 Mr. Bryant 35 were previously known from the Bahamas, 15 were 

 known to science but not definitely reported from the Bahamas, 4 

 new species or varieties have been added to the fauna by Mr. Bryant 

 and 14 have been contributed from inedited material in the National 

 Museum, making 18 new forms first described in this report, which 

 covers, in all, 66 species. The total now known from the Bahamas 

 is 174 species and marked varieties. 



List of the Spe< 11- Collected by Mr. Bryant, with Descrip- 

 tions of Several New Forms. 



Oleacina solidula Pfciffer. 



Mangrove Cay, south bight of Andros : Nassau, on the Grantstown 

 road and near Johnson's place ; Little Abaco near Marsh Harbor 

 and Nield's, and on the south side at Mathews Point. 



The species appears to be common and quite uniform in adult 

 characters. 

 Plcurodonte provisoria Pfeiffer.
