 Anas glocitans,  Linn. 
 Querquedula glocitans,  Vigors. 
 T he  Bimaculated Teal is so  named from  the two  large spots of brown  on the face and neck:  we believe,  however  
 , that these brown markings vary in the depth of their colour at different seasons;  at least we find such to be  
 the case in an allied species from China, Querquedula formosa, of which examples are now living in the Cardens  
 o f  the Zoological  Society,  and which  possess marks  of  a similar character;  these at opposite seasons  are  of  
 a very different colour,  changing  from  rich  brown to light tawny grey.  We are not aware of the existence of  
 male and female examples of  this  very rare  species  in any collection, either public or private,  except those in  
 the  Museum  of  the  Zoological  Society of London,  to  which  they were  presented with  the  rest  of  his  fine  
 collection  by N. A. Vigors, Esq.  These  were taken  in  a decoy in  the year  1812; and it is also recorded that  
 a male was  taken  in a similar manner in  1771, as described by Pennant  in  his  British Zoology.  So rare does  
 this Teal  appear to be on  the continent of Europe that we do not find it even alluded  to  by any writer except  
 Pallas, who  describes it  as a native of the high  northern regions of Siberia.  In point of affinity this bird possesses  
 every characteristic feature of the true Teals,  of  which limited  group  it  is  the largest species  that  has  
 come under our notice. 
 With  regard to  its habits, manners,  and food,  they are  in  all probability the same as in the other species of  
 the genus.  No  account of them has yet been  published;  nor,  indeed,  is it to  be expected that we shall  easily  
 acquire much information respecting  the inhabitants of a portion of the globe  so remote,  and with  which  we  
 have  so little intercourse. 
 Crown of  the head deep  chestnut  brown;  sides of  the head  and  neck  rich green  interrupted by two large  
 blotches  of  brown,  one situated  near  the  base  of  the beak,  the  other  on  the  side of  the  neck;  chest  rich  
 chestnut regularly dotted with oval  spots  of black;  the whole  of  the back and flanks light tawny grey,  thickly  
 pencilled with regular zigzag lines of black; shoulders greyish brown ;  quills blackish brown; speculum changeable  
 green  and blue,  edged  anteriorly with a narrow line of tawny yellow and posteriorly with  a line of white;  
 a row of coverts, which are internally edged with  tawny yellow and  externally with  black, hang over the wing;  
 rump  and  upper and under  tail-coverts  greenish  black;  two middle tail-feathers black,  the  rest  pale  brown,  
 margined with white;  a mark of buff separates the green  under tail-coverts from  the  lower part of the  belly,  
 which is greyish white;  bill  olive brown,  more yellow at the  base;  feet dark olive  brown. 
 The  female has  the  head  and  neck  pale  buff minutely spotted with small  markings  of  black;  the upper  
 surface  blackish  brown,  each  feather  having a margin  of  tawny  brown;  chest  reddish brown,  each  feather  
 being darker in  the centre;  shoulders of the wing as in  the male;  speculum  green above  with purple reflections  
 passing  into  black,  and  edged with white;  quills and tail  brown;  the feathers  of  the latter edged with  
 tawny white;  under surface greyish white;  legs  more inclined  to orange.
