 The  singular spoon-sbaped  bill  bordered with  numerous  delicate laminie,  which  characterises  several species  
 of this  interesting family,  has been  considered of sufficient importance to constitute  the  distinctive  characters  
 , o f a  group,  to  which  the  name  of Rhynchaspis  has been  applied  by  Dr.  Leach,  and  that  of  Spat/mlea  by  
 Dr.  Fleming, while Mr  Swamson retains  the  title of Mas to  this group,  as  frod,  the peculiar  structure of its  
 beak,  be considers the Shoveller to be thp  type  of the  true grass-feeding ducks:  we have restricted the term  
 Mas.  however,  to  the group comprehending the Common Wild Duck;  and  having been so employed  by our-  
 .selves,  and the  term Spathalea having scarcely been  adopted,  we prefer the generic  title of Blmc/mpis  
 This group consists  of several  species,  which  are  almost  universally  though  sparingly  distributed  The  
 range  of  the present species extends  throughout the  temperate portions  of Europe,  the northern  regions  of  
 fnca  and nearly the whole  of India:  in  our  island it appears to  be somewhat limited;  doubtless a few breed  
 annually ,n  our  marshes,  and Mr.  Selby informs us that he  has  a male in  his  collection  killed  in  the  month  '  
 61  July  at which period ,t undergoes that  transition of plumage  which  assimilates it  to  the female,  a change  
 the  utility o f which  has not as  yet  been  philosophically explained.  As  we  have observed  that  this  change  is  
 common  to  the  males  of  those species that more  especially breed  in marshes,  among  reeds, &c  and  as  it  
 generally  takes place at the period  of incubation, may it not serve as a protectiob  to  the species  by rendering  
 the fostering  parent  less  conspicuous  at  this  critical  period  than  he  would  be  were  he  to  retain  the  gav  
 nuptial dress,  which  would present so  strong a contrast  to  the  sombre-tinted  vegetation  among  which  it  is  
 .  necessary for him  to remain,  until  the young are  able  to  provide for themselves ? 
 ’  It  is  said to prefer lakes and  inland  waters  tdi tlje sea  and saline marshes,  a  circumstance to  be accounted  
 by the pe“"1,ar I,ature of  lts f° °d.  "'■>»  o d i s t s  of  the  larva, of insects,  and freshwater vegetables  such  
 as grasses and duckweed:  from  this kind of food its flesh,  as might be expected,  is  both delicate and  tender  
 and m  high  esteem for the  table. 
 Its mode  of  nidification  is  very like  that of  the Common Wild Duck,  the  nest being  constructed  among  
 coarse  herbage  m  the  central  parts  of marshes,  add  the eggs,  being from  ten  to/twelve in number  of  a  pal!
