  This 
  goiuis 
  is 
  cluiractorizod 
  by 
  a 
  thin-otl<2:o(l 
  lower 
  lip 
  projecting 
  

   fonvard 
  horizontally, 
  not 
  curved 
  or 
  folded 
  downward; 
  the 
  teeth 
  in 
  the 
  

   lower 
  lip 
  are 
  setiform 
  or 
  ciliform, 
  partly 
  embedded 
  or 
  conspicuous; 
  

   teeth 
  in 
  upper 
  lip 
  similar. 
  The 
  outer 
  row 
  of 
  teeth 
  in 
  both 
  lips 
  is 
  

   usually 
  more 
  piominent, 
  with 
  simple 
  tips, 
  and 
  if 
  inner 
  rows 
  occur 
  these 
  

   are 
  either 
  bifid 
  or 
  trifitl, 
  at 
  least 
  on 
  adults 
  (apparently 
  the 
  teeth 
  in 
  

   certain 
  species 
  of 
  this 
  genus 
  become 
  bifid 
  or 
  even 
  trifid 
  in 
  large 
  adults); 
  

   a 
  symphyseal 
  knob 
  present 
  at 
  tip 
  of 
  lower 
  jaw; 
  scales 
  cycloid; 
  the 
  

   preorbital 
  has 
  the 
  front 
  edge 
  straight 
  or 
  nearly 
  so 
  without 
  a 
  con- 
  

   spicuous 
  concavity; 
  maxillary 
  and 
  premaxillary 
  not 
  bent 
  downward 
  

   posteriorly, 
  but 
  in 
  line 
  with 
  the 
  front 
  edge 
  of 
  preorbital; 
  nostrils 
  in 
  

   line 
  with 
  the 
  upper 
  edge 
  of 
  the 
  orbit, 
  widely 
  spaced, 
  the 
  anterior 
  is 
  

   closer 
  to 
  groove 
  behind 
  upper 
  lip 
  than 
  to 
  posterior 
  nostril; 
  adipose 
  

   e^yelid 
  present; 
  upi)er 
  lip 
  usually 
  not 
  so 
  wide 
  as 
  distance 
  between 
  

   nostrils; 
  teeth 
  probably 
  absent 
  on 
  vomer, 
  palatines, 
  and 
  tongue; 
  

   posterior 
  edge 
  of 
  preorbital 
  narrower 
  than 
  space 
  between 
  nostrils; 
  

   margin 
  of 
  lower 
  jaw 
  angular; 
  gill 
  membranes 
  extending 
  far 
  forward, 
  

   not 
  broadly 
  connected 
  across 
  isthmus. 
  

  

  In 
  this 
  genus 
  I 
  find 
  that 
  in 
  small 
  specimens 
  of 
  certain 
  species 
  the 
  

   teeth 
  have 
  simple 
  tips, 
  but 
  later 
  the 
  inner 
  teeth 
  have 
  bifid 
  tips 
  and 
  in 
  

   the 
  largest 
  adults 
  some 
  possess 
  trifid 
  tips. 
  The 
  teeth 
  of 
  the 
  outer 
  row 
  

   usually 
  have 
  simple 
  tips, 
  but 
  in 
  some 
  large 
  specimens 
  these 
  are 
  bifid 
  

   too. 
  

  

  I 
  have 
  examined 
  too 
  many 
  collections 
  of 
  the 
  numerous 
  species 
  

   referable 
  to 
  this 
  genus 
  to 
  list 
  them 
  here. 
  The 
  localities 
  represented 
  

   are: 
  Europe, 
  both 
  coasts 
  of 
  Africa, 
  both 
  coasts 
  of 
  North 
  and 
  South 
  

   America, 
  West 
  Indies, 
  Hawaiian 
  Islands, 
  Australia, 
  Oceania, 
  Japan, 
  

   coast 
  of 
  Asia, 
  in 
  temperate 
  and 
  tropical 
  seas.

  This 
  genus 
  is 
  characterized 
  by 
  a 
  moderately 
  thin 
  lower 
  lip 
  i)rojecting 
  

   horizontally 
  forward, 
  with 
  a 
  single 
  row 
  of 
  small, 
  close-set, 
  incisorliko 
  

   t<'eth 
  rather 
  finnly 
  set; 
  teeth 
  in 
  upper 
  jaw 
  similar 
  and 
  in 
  one 
  row; 
  all 
  

   teeth 
  with 
  simple 
  tips; 
  no 
  iiuier 
  rows 
  of 
  teeth 
  in 
  either 
  jaw; 
  a.symphy.s- 
  

   eal 
  knob 
  at 
  inside 
  tip 
  of 
  lower 
  jaw; 
  scales 
  cyoloid; 
  front 
  edge 
  of 
  pre- 
  

   orbital 
  straight, 
  no 
  concave 
  notch 
  ; 
  maxillary 
  and 
  premaxillary 
  not 
  bent 
  

   downward 
  but 
  nearly 
  straight, 
  in 
  line 
  with 
  front 
  edge 
  of 
  preoibital; 
  

   maxillary 
  not 
  exposed 
  posteriorly; 
  nostrils 
  on 
  level 
  of 
  upper 
  edge 
  of 
  

   orbit 
  rather 
  close 
  together, 
  the 
  anterior 
  much 
  farthcT 
  from 
  groove 
  

   behind 
  upper 
  lip 
  than 
  from 
  posterior 
  nostril, 
  no 
  adipose 
  e^'elid; 
  

   narrow 
  band 
  of 
  teeth 
  on
