  On 
  the 
  Anatomy 
  &c. 
  of 
  some 
  Teleostean 
  Fishes. 
  

  

  Recent 
  genera 
  are 
  Adioryx, 
  Starks 
  (' 
  Science/ 
  xxviii. 
  

   1908, 
  p. 
  614), 
  Holocentrut, 
  Scopoli, 
  Myripristis, 
  Cuv. 
  (with 
  

   toothed 
  maxillary), 
  and 
  Ostichthys, 
  Langsdorff. 
  The 
  Creta- 
  

   ceous 
  Homonotus, 
  Dixon, 
  seems 
  to 
  be 
  near 
  Myripristis 
  ; 
  the 
  

   fish 
  described 
  by 
  Dr. 
  Smith 
  Woodward 
  from 
  the 
  Chalk 
  of 
  

   Kent 
  under 
  the 
  name 
  Trachithyioides 
  ornatus 
  is 
  known 
  only 
  

   from 
  the 
  skull, 
  which 
  is 
  very 
  similar 
  to 
  that 
  of 
  some 
  recent 
  

   species 
  of 
  Myripristis, 
  although 
  none 
  of 
  them 
  show 
  the 
  

   principal 
  frontal 
  ridges 
  quite 
  so 
  far 
  apart 
  posteriorly 
  nor 
  the 
  

   radiating 
  ridges 
  so 
  few. 
  Dinopteryx, 
  A. 
  S. 
  Woodward, 
  with 
  

   seven 
  anal 
  spines, 
  may 
  be 
  provisionally 
  placed 
  in 
  this 
  family. 
  

  

  I 
  propose 
  the 
  new 
  generic 
  name 
  Caproberyx 
  for 
  the 
  fish 
  

   from 
  the 
  Chalk 
  of 
  Kent 
  described 
  by 
  Dr. 
  Smith 
  Woodward 
  

   under 
  the 
  name 
  Berycopsis 
  major 
  (Palajontogr. 
  Soc. 
  1902, 
  

   p. 
  11, 
  pi. 
  ii. 
  fig. 
  2). 
  Of 
  the 
  vortical 
  fins 
  only 
  the 
  anal 
  spines 
  

   are 
  known, 
  but 
  the 
  head 
  and 
  pectoral 
  arch 
  are 
  well 
  preserved 
  

   and 
  indicate 
  relationship 
  to 
  the 
  Holocentridse. 
  In 
  the 
  short 
  

   prsemaxillary 
  processes 
  and 
  the 
  absence 
  of 
  a 
  prseopercular 
  spine 
  

   Caproberyx 
  resembles 
  Myripristis, 
  in 
  the 
  expanded 
  prse- 
  

   orbital 
  and 
  the 
  weak 
  principal 
  and 
  numerous 
  radiating 
  frontal 
  

   ridges 
  Holocentrus. 
  Bnt 
  it 
  differs 
  from 
  both 
  in 
  the 
  greater 
  

   prominence 
  of 
  the 
  occipital 
  crest, 
  which 
  has 
  the 
  upper 
  edge 
  

   thickened 
  and 
  longitudinally 
  ridged 
  ; 
  in 
  this 
  and 
  in 
  some 
  

   other 
  features 
  it 
  shows 
  considerable 
  similarity 
  to 
  Antigonia, 
  

   and 
  it 
  may 
  be 
  that 
  this 
  resemblance 
  is 
  due 
  to 
  real 
  affinity 
  and 
  

   that 
  Caproberyx 
  is 
  nearest 
  of 
  all 
  the 
  Berycoids 
  to 
  the 
  

   Zeomorphi. 
  

  

  The 
  Berycomorphi 
  as 
  above 
  restricted 
  do 
  not 
  include 
  the 
  

   Stephanoberycidse 
  and 
  Melamphaidse. 
  These 
  are 
  probably 
  

   derived 
  from 
  the 
  same 
  stock 
  as 
  the 
  Berycomorphous 
  fishes, 
  

   resembling 
  them 
  in 
  the 
  structure 
  of 
  the 
  protractile 
  mouth, 
  and 
  

   in 
  the 
  caudal 
  fin, 
  which 
  has 
  19 
  principal 
  rays, 
  17 
  of 
  which 
  

   are 
  branched, 
  and 
  the 
  procurrent 
  rays 
  spinous. 
  Not 
  much 
  

   importance 
  can 
  be 
  attached 
  to 
  the 
  presence 
  of 
  large 
  mucous 
  

   cavities 
  on 
  the 
  head. 
  They 
  differ 
  from 
  typical 
  Beryco- 
  

   morphi 
  in 
  the 
  toothless 
  palate, 
  the 
  absence 
  of 
  a 
  subocular 
  

   shelf, 
  and 
  the 
  triangular 
  shape 
  of 
  the 
  single 
  supramaxillary, 
  

   but 
  especially 
  in 
  the 
  absence 
  of 
  an 
  orbitosphenoid. 
  I 
  find 
  

   that 
  in 
  both 
  Melamphaes 
  and 
  Stephanoberyx 
  the 
  widely 
  sepa- 
  

   rated 
  alisphenoids 
  extend 
  well 
  forward 
  between 
  the 
  orbits, 
  

   but 
  do 
  not 
  seem 
  to 
  be 
  bridged 
  by 
  an 
  orbitosphenoid 
  *. 
  

  

  * 
  I 
  have 
  had 
  no 
  skeletons 
  for 
  examination, 
  and 
  in 
  these 
  two 
  genera, 
  as 
  

   in 
  Anomalops 
  and 
  Diretmus, 
  I 
  have 
  only 
  been 
  able 
  to 
  see 
  the 
  arrangement 
  

   of 
  the 
  interorbital 
  bones 
  by 
  a 
  temporary 
  displacement 
  of 
  one 
  eye 
  in 
  a 
  

   spirit-specimen.
