MR.  J.  GOULD'S  DESCRIPTION  OF  A  NEW  SPECIES 
minck  has  altered  its  specific  name,  and  has  designated  it  as  the  Eur.  Corydon. 
M.  Lesson  has  remarked  on  the  extraordinary  breadth  and  strength  of  its  bill,  on  the 
dilatation  and  swelling  posteriorly  of  the  margins  of  this  organ  in  such  a  manner  as  to 
render  the  lower  mandible  entirely  thin  at  its  base,  on  the  keel  and  the  uniform  con- 
vexity of  the  bill,  on  the  rounded  and  indistinct  nostrils  in  some  degree  hidden  by  the 
hairs  and  the  small  feathers  of  the  front,  on  the  naked  circle  surrounding  the  eyes,  &c., 
as  on  characters  sufiicient  to  distinguish  it  as  the  type  of  a  subgenus,  for  which  he  pro- 
poses the  name  of  Corydon;  the  species  being  designated  by  him  Corydon  Temminckii^ . 
It  would,  however,  be  preferable  to  retain  the  original  specific  name,  and  to  call  the 
bird  Corydon  8umatranus. 
The  third  addition  to  the  genus  to  which  I  have  alluded  is  that  by  MM.  Lesson  and 
Garnot,  who  have  figured  and  described  in  their  beautiful  work,  the  Zoological  Portion 
of  the  '  Voyage  de  la  Coquille'^,  a  bird  obtained  by  M.  Lesson  in  New  Guinea,  to 
which  they  have  given  the  name  of  Eurylaimus  Blainvillii.  As  I  have  had  no  oppor- 
tunity of  examining  this  bird,  and  am  acquainted  with  it  only  through  the  medium  of 
the  figure  published  in  the  work  just  quoted,  I  must  speak  with  diffidence  respecting  it : 
but  I  cannot  venture  to  regard  it  as  really  a  Eurylaimus,  possessing  as  it  evidently  does 
characters  at  variance  with  all  others  of  that  group.  Its  lengthened  and  forked  tail,  its 
feeble  tarsi,  and  its  narrow  bill  furnished  with  stiff  bristles,  appear  to  indicate  its  natural 
position  to  be  among  the  true  Flycatchers. 
There  remain  then,  in  the  defined  genus  Eurylaimus,  only  the  Eur.  Horsfieldii,  Temm.^, 
the  type  of  the  genus,  and  described  as  such  by  Dr.  Horsfield  in  the  'Transactions  of  the 
Linnean  Society'*  under  the  name  of  Eur.  Javanicus^ : — the  Eur.  ochromalus,  Rafil.^, 
of  which  Eur.  cucullatus,  Temm.^,  is  a  synonym  : — and  the  species  for  which  I  propose 
the  name  of  Eur.  lunatus.  The  latter  presents,  it  is  true,  some  minute  ditFerences  from 
the  two  previously  mentioned  birds  ;  but  as  these  differences  consist  principally  in  the 
filamentous  termination  of  the  primary  and  tail-feathers,  and  in  the  singular  crescent- 
shaped  row  of  silvery  feathers  which  adorns  the  neck  of  the  male,  they  are  by  no  means 
likely  to  exercise  any  influence  over  the  habits  of  the  bird,  which  may  consequently  be 
placed  with  the  true  Eurylaimi.    It  may  be  thus  characterized : 
Eurylaimus  lunatus.

^  Dr.  Horsfield  having  withdrawn  the  claim  of  priority  in  naming  this  species,  and  having  allowed  another 
name  to  be  substituted  for  that  originally  given,  the  one  substituted  by  M.  Temminck  and  allowed  by  Dr.  Hors- 
field will  probably  be  generally  adopted.
