  PART

   SPECIES 
  FROM 
  MONTEREY 
  BAY. 
  

  

  It 
  is 
  largely 
  through 
  the 
  kindly 
  interest 
  of 
  Dr. 
  Harold 
  Heath, 
  

   Messrs. 
  Walter 
  Weymouth, 
  and 
  William 
  F. 
  Allen 
  that 
  the 
  writer 
  

   has 
  been 
  enabled 
  to 
  obtain 
  specimens 
  of 
  the 
  species 
  here 
  noted. 
  Most 
  

   of 
  them 
  were 
  taken 
  while 
  dredging 
  in 
  the 
  shallow 
  water 
  near 
  shore 
  in 
  

   Monterey 
  Bay.

  Three 
  specimens 
  of 
  this 
  species 
  were 
  dredged 
  from 
  the 
  sandy 
  bottom 
  

   opposite 
  Monterey 
  at 
  a 
  depth 
  of 
  about 
  5 
  fathoms. 
  They 
  measure 
  65 
  

   to 
  76 
  millimeters. 
  The 
  myocommata 
  number 
  as 
  follows:

  ICOSTEUS 
  iENIGMATICUS 
  Lockington. 
  

  

  A 
  young 
  example 
  of 
  this 
  form 
  was 
  found 
  on 
  the 
  beach 
  near 
  Pacific 
  

   Grove. 
  It 
  measures 
  about 
  80 
  millimeters. 
  Spicules 
  are 
  present 
  along 
  

   the 
  lateral 
  line 
  and 
  on 
  the 
  rays 
  of 
  the 
  dorsal, 
  anal, 
  and 
  caudal 
  fins. 
  

   The 
  color 
  differs 
  from 
  that 
  of 
  the 
  adult, 
  there 
  being 
  7 
  dark 
  vertical 
  

   bands 
  on 
  the 
  body. 
  These 
  are 
  confined 
  to 
  the 
  region 
  extending 
  be- 
  

   tween 
  the 
  interneurals 
  and 
  interhaemals, 
  which 
  are 
  plainly 
  visible 
  in 
  

   the 
  translucent 
  body. 
  Before 
  the 
  anterior 
  band 
  and 
  just 
  behind 
  the 
  

   occiput 
  is 
  a 
  round 
  spot. 
  The 
  posterior 
  band 
  is 
  at 
  the 
  base 
  of 
  the 
  

   caudal 
  fin. 
  The 
  bands 
  are 
  somewhat 
  narrower 
  than 
  the 
  light 
  inter- 
  

   spaces. 
  The 
  third 
  band, 
  counting 
  from 
  the 
  caudal, 
  unites 
  above 
  and 
  

   below 
  with 
  large, 
  dark 
  spots. 
  Similar 
  spots 
  are 
  above 
  and 
  below 
  the 
  

   fifth 
  band 
  from 
  the 
  caudal, 
  and 
  there 
  is 
  an 
  elongate 
  spot 
  at 
  the 
  base 
  

   of 
  the 
  anterior 
  third 
  of 
  the 
  dorsal 
  fin. 
  The 
  bands 
  and 
  spots 
  on 
  the 
  

   opposite 
  (left) 
  side 
  of 
  the 
  body 
  differ 
  somewhat 
  in 
  their 
  relations 
  to 
  

   each 
  other. 
  The 
  caudal 
  and 
  anal 
  are 
  broadly 
  edged 
  with 
  blackish; 
  

   the 
  pectoral 
  narrowly 
  bordered 
  with 
  black; 
  ventrals 
  black. 
  When 
  

   fresh, 
  the 
  head 
  and 
  body 
  were 
  translucent, 
  with 
  a 
  light 
  straw 
  tint. 
  

   There 
  are 
  53 
  rays 
  in 
  the 
  dorsal 
  fin, 
  38 
  in 
  the 
  anal.

  ICELINUS 
  QUADRISERIATUS 
  (Lockington). 
  

  

  A 
  specimen 
  having 
  the 
  ventrals 
  deep 
  black 
  was 
  taken 
  at 
  a 
  depth 
  of 
  

   10 
  or 
  12 
  fathoms 
  near 
  Pacific 
  Grove.
