  Cat. 
  No. 
  74129, 
  U.S.N.M., 
  19.3 
  cm. 
  in 
  length, 
  taken 
  with 
  

   a 
  beam 
  trawl 
  at 
  station 
  5290 
  (lat. 
  13° 
  40' 
  09'' 
  N.; 
  long. 
  120° 
  59'

   E.), 
  in 
  Batangas 
  Bay, 
  Luzon, 
  at 
  a 
  depth 
  of 
  214 
  fathoms, 
  on 
  a 
  bottom 
  

   of 
  lava 
  and 
  gravel. 
  

  

  From 
  N. 
  macrops 
  Gunther 
  this 
  species 
  differs 
  in 
  having 
  the 
  head 
  

   shorter, 
  tip 
  of 
  snout 
  more 
  prominent 
  and 
  fleshy, 
  maxillary 
  shorter 
  

   (equal 
  to 
  snout 
  plus 
  eye), 
  ventrals 
  shorter, 
  vomerine 
  teeth 
  in 
  a 
  tri- 
  

   angular 
  patch 
  (Y-shaped 
  in 
  macrops), 
  and 
  body 
  crossed 
  by 
  well- 
  

   defined 
  Hnds 
  of 
  darker 
  coloration. 
  From 
  the 
  alleged 
  cotype 
  of 
  

   N. 
  sivicola 
  (Jordan 
  and 
  Snyder), 
  from 
  Yokohama, 
  in 
  the 
  United 
  

   States 
  National 
  Museum, 
  which 
  we 
  have 
  examined, 
  it 
  differs 
  in 
  having 
  

   9 
  or 
  10 
  scales 
  from 
  origin 
  of 
  dorsal 
  to 
  and 
  including 
  lateral 
  line 
  (12 
  or 
  

   13 
  in 
  sivicola), 
  the 
  mouth 
  smaller, 
  maxillary 
  much 
  shorter, 
  distance 
  

   from 
  snout 
  to 
  vent 
  much 
  less, 
  distance 
  from 
  lower 
  pectoral 
  base 
  to 
  

   origin 
  of 
  anal 
  less 
  than 
  length 
  of 
  head 
  (considerably 
  greater 
  in 
  

   sivicola), 
  and 
  vomerine 
  teeth 
  in 
  a 
  triangular 
  instead 
  of 
  a 
  Y-shaped 
  

   patch. 
  The 
  Yokohama 
  specimen 
  of 
  N. 
  sivicola 
  is 
  much 
  faded, 
  and 
  

   there 
  are 
  no 
  traces 
  of 
  darker 
  cross-bands 
  on 
  body 
  or 
  fins. 
  

  

  Examples 
  from 
  Suruga 
  and 
  Sagami 
  Bays, 
  Japan, 
  identified 
  by 
  

   Jordan 
  and 
  Starks 
  as 
  Watasea 
  sivicola, 
  agree 
  very 
  closely 
  with 
  our 
  

   examples 
  of 
  N. 
  fasciatus, 
  but 
  their 
  drawing 
  fails 
  to 
  show 
  the 
  banded 
  

   appearance 
  of 
  our 
  examples. 
  Their 
  statement 
  " 
  greater 
  distance 
  from 
  

   snout 
  to 
  vent" 
  should 
  read 
  "lesser 
  distance."

  This 
  genus 
  differs 
  from 
  NeohytJiites 
  in 
  the 
  relatively 
  weaker, 
  more 
  

   porous 
  character 
  of 
  the 
  bones 
  of 
  the 
  head; 
  more 
  deciduous 
  scales; 
  

   margin 
  of 
  preopercle 
  armed 
  with 
  three 
  small 
  sharp 
  spines; 
  ventrals 
  

   reduced; 
  pyloric 
  coeca 
  small 
  or 
  rudimentary, 
  in 
  reduced 
  number; 
  

   lower 
  pectoral 
  rays 
  detached, 
  not 
  connected 
  b}^ 
  membrane; 
  pseudo- 
  

   branchise 
  very 
  small 
  (said 
  to 
  be 
  absent 
  in 
  some 
  species).
