and restricted habitats, had become roodified in structure, 

 and a much larger ninuber of generic forms existed than 

 had hitherto been supposed. 



The following were the genera which Dr. Sliarpe

 Cab. ; 3. Hypotanidia, Eeiclieub. : 4. Cahalus, Hutton ; 

 5. Eulaheoniis, Gould : 6, TrichoUmnas, gen. u. ; 7. Gym-

 Mantell ; 52. Fid'ica, Briss. : 53. Leguatia, Schl. Besides 

 these genera there were a few fossil forms, the exact position 

 of whicli it was difficult to define. 



Dr. Sharpe stated that he had lately examined the type 

 specimen of GalUrallus bracliyptenis, from the Caen Museum. 

 For the loan of the specimen he was indebted to Professor 

 Joyeux-Laffine, the Director of that ]\Iuseum. Dr. Sharps 

 pointed out that the species had been the subject of much 

 controversial opinion, but it was evidently of the same species 

 as GalUrallus fuscus of Du Bus, which must therefore be 

 known ks' Ocydromus br achy jA ems (La£r.). The species 

 identified bv Sir Walter Buller as 0. brachypterus, and
