 from  *51  to  *48  in. 
 In  some  seasons,  according to Mr.  Gray,  this Titmouse  is  
 more  plentiful  than  in  others,  but  his  conjecture  that  the  
 increase  arises  from  the  arrival  of  migratory  flights  from  
 abroad  is  unsupported  by  evidence,  and  the  fact  is  more  
 likely  due  to  causes  affecting  the  supply  of  food  to  the  
 home-bred  birds.  That  the  Crested  Titmouse  does  occasionally  
 in winter wander from  its  usual haunts is,  however,  
 shown  by  its  occurrence  in  Argyleshire,  in  January,  1838,  
 mentioned  by  Macgillivray,  and  near  Dumbarton,  as  communicated, 
   by  Dr.  Smith  in  1857,  to  the  Royal  Physical  
 Society  of  Edinburgh.  Dr.  Saxby  saw  two  in  Perthshire  
 early  in April,  1858,  and he  also  reports  (Zool.  p.  7998)  his  
 having  observed  a  small  flock  at  Craig  Lockhart  near  
 Edinburgh,  February  25tli,  1862,  whose  actions  he  agreeably  
 describes.  It  is  said  to  have  strayed even  to  England  
 and  Ireland,  and  eight  instances  of  its  supposed  occurrence  
 in  the  former  are  enumerated  by  Mr.  Harting  in  his  
 useful  ‘Handbook,’  to  which  a  ninth,  since  recorded  by  
 Mr.  M.  Simpson  (Zool.  s.s.  p.  3021)  has  to  be  added;  
 while  Mr.  Blake-Knox informed Messrs.  Sharpe  and Dresser  
 of  some  three  or more  captures  in  Ireland.  Many of  these  
 cases,  on  enquiry, cannot be  substantiated. 
 The Crested  Titmouse  inhabits  Norway,  Sweden,  Finland  
 and  Russia  to  about lat.  64° N.,  but  does  not  appear  to  be  
 found  beyond  the  Ural,  though  it  is  recorded  from  the  
 Caucasus.  Near Odessa  it  occurs  only on  passage  and  but  
 rarely.  There  is  no  report  of  its  being met with  in  Turkey,  
 but it  is common  in Hungary  and  thence,  through  the Austrian  
 dominions,  to  the  north  of  Italy,  in  the  mountains  of  
 which  it  breeds,  but,  according to Dr.  Salvadori’s recent work  
 on  the birds  of  that  country,  its  range  there  is  by no means  
 so  wide  as  several  authors have  alleged.  In  Spain  it  occurs  
 even  near Gibraltar,  and  sometimes  in  Portugal.  I t  is  not  
 rare  in  France  or  Germany,  but  in  each  as  well  as  in  
 Belgium  and  Holland  it  is  very local.  In  nearly all  these  
 countries,  and  in  those  which  lie  between  them,  it  is  very 
 partially  distributed,  usually  abiding  in  forests,  feeding  on  
 the  fir-frequenting  insects,  or,  in  default  of  them,  on  the  
 seeds  of  the firs.  But  this  is not  always  the  case,  since Sir  
 W.  Jardine  once  saw  it  in November  in  the  apple-orchards  
 near  Havre-de-Grace,  and  Hoy furnished  this work with  the  
 information that,  according to his  experience, it  seems  partial  
 to woods where  firs and  oaks  are mixed,  the holes  in the  oaks  
 generally  serving  it  for  its  nests.  This  same  observer  added  
 that  its  note  has  some  resemblance  to  that  of  the  Coal-  
 Titmouse,  but  a peculiar  shake  at  the  finish  makes  it  distinguishable  
 ;  its  simple  call-note  is  also  somewhat  different. 
 The  adult male has  the  bill  nearly black:  the  irides h az el:  
 head dull black;  each feather tipped with  greyish-white,  those  
 on  the  forehead  rounded,  those  behind  much  elongated,  
 pointed  and  slightly recurved,  forming  a  conspicuous  cre st;  
 a black line  runs  from the bill to the  eye,  and  thence  above  
 the  ear-coverts to  the  back  of  the  head, whence  it  descends  
 behind  the  cheeks, which  are white mottled  with  black.  To  
 this  succeeds  a white band on  each  side,  followed by  a  second  
 black  crescentic  line ;  the back, wings  and  tail-coverts,  liair-  
 brown ;  quills  rather  darker;  chin  and  throat,  black,  meeting  
 the  second black line  on  the  side  of  the  neck;  breast,  belly  
 and  flanks,  dirty white,  tinged with  dull  buff  on  the  sides;  
 lower  tail-coverts  dull  buff;  quills  beneath,  shining  grey:  
 legs,  toes  and claws,  lead-colour. 
 The whole  length  is  four  inches  and  a  half.  From  the  
 carpal  joint to  the  tip  of  the  wing,  two  inches  and  a  h a lf:  
 the  third  and fifth primaries  equal  and  a  little  shorter  than  
 the  fourth which  is  the  longest  feather  in  the wing. 
 The  female has  less black on  the  chin  and  throat than the  
 male,  and  a  somewhat  shorter  crest.  The  young  are  said  to  
 resemble  the  adults,  but have  the  crest  shoi'ter. 
 Kaup  proposed  generic  distinction,  under  the  name  of  
 Lophophanes, for this  species  and  the North-American Parus  
 bicolor.  In   the  case  of  the  former  such  separation  is  not  
 warranted  by  any known  structural  peculiarity ;  whether  it  
 is required  in  the  case  of the  latter need  not here  concern  us.
