 Helmeted  Honey-eater. 
 Ptilotis  cassidix, Jard.  in Proc.  of Zool. Soc.,  1866, p. 558. 
 W hile  on  a   visit  to  Scotland  in  the autumn  of  the year  1866,  my friend  Sir William  Jardine sent to me  in  
 the Highlands  a well-executed  drawing,  made by his  daughter, Mrs. Strickland,  of a bird which  he  believed  
 to  be  new  to  science,  and  which  had  been  obtained  by  him  in  Edinburgh  from  among  a  collection  
 of  ordinary  Australian  species.  On  inspecting  the  drawing,  I  at  once  perceived  that  Sir William  was  
 right in  his  conjecture,  and  that  the  bird  was  not  only  new,  but  one of  the  finest species of  the genus  
 Ptilotis  yet  discovered.  Subsequently  the  original  specimen  was  sent  to  me  to  be  exhibited  at  the  
 December  meeting  of  the  Zoological  Society of London;  and  the  name  of Ptilotis cassidix was  assigned  
 to  it.  Almost simultaneously with  the arrival  of the above  and  a second  example  in Edinburgh,  others  were  
 transmitted  to  London;  the  latter  were  obtained  at Western-Port  Bay,  near  Port  Phillip  Heads,  iu  the  
 colony  of V ictoria;  and  now that  the  bird  is  figured,  and  the characters  by which  it  may be distinguished  
 from  its  nearest ally  (the Ptilotis auricomis')  are pointed out,  we  shall  not,  I  trust,  long  remain  ignorant  of  
 its  habits and  economy. 
 The  P.  cassidix  differs  from P. auricomis  in  its  much  larger size,  in the dark olive-black colouring of  its  
 upper surface, wings,  and  tail,  in  the greater amount of  black surrounding the  eye,  in  the erect tuft of wax-  
 yellow feathers  on  the  forehead,  in  all  but  the  four central  tail-feathers  being  tipped with white,  and  in  the  
 chin  and  centre of the throat being  black  or black  interspersed with  light yellow. 
 This  I  am  sorry to  say is all  I  have  to communicate respecting a species which  must  hereafter  be placed  
 in  our  museums  at  the  head  of  the  genus Ptilotis,  the  members  of which  are  nearly as  numerous as  the  
 various  kinds of Eucalypti,  upon  the  flowers  of which  they  mainly subsist,  and with which  their yellow  ear-  
 tufts  vie  in  beauty of colouring. 
 The following  is  a description and admeasurement of one of my own  specimens, which  does not materially  
 differ  from that exhibited  at the meeting of  the Zoological  Society above alluded  to. 
 Raised  tuft  of  feathers  on  the  forehead,  crown,  nape,  breast,  and  under surface wax-yellow;  cheeks  and  
 ear-tufts  rich  yellow;  lores,  sides  of  the  face,  and  ear-coverts  jet-black;  all  the  upper  surface,  wings,  and  
 tail  olive-black;  primaries  and  lateral  tail-feathers  fringed  with  wax-yellow;  all  but  the  four  central  tail-  
 feathers  tipped with  yellowish-white;  bill black;  feet bluish. 
 Total  length  of  the  male  8 i inches;  bill  £ ;  wing  4 i ;   tail  4 f ;  tarsi  1.  The  admeasurements  of  the  
 female are  considerably less. 
 In  some specimens  I  find  the black of the throat interspersed with yellow;  these  I suspect are females,  and  
 I  also believe that  this  sex,  like the young birds,  has  the upper  surface more or less  tinged with wax-yellow. 
 The  figure  is  rather less  than  the  natural  size.
