  propose 
  the 
  new 
  generic 
  name 
  Lamprichthys 
  lor 
  

   Haplochilus 
  tanganicanus, 
  Bouleng., 
  a 
  silvery 
  fish 
  which 
  

   differs 
  from 
  Haplochilichthya 
  in 
  the 
  strongly 
  compressed 
  

   body, 
  the 
  very 
  long 
  anal 
  (in, 
  and 
  the 
  more 
  numerous 
  vertebrae

  The 
  Oligocene 
  and 
  Miocene 
  Prolebias, 
  Sauv., 
  seems 
  to 
  be 
  

   related 
  to 
  Fundulw; 
  it 
  has 
  32 
  to 
  34 
  vertebras

  3. 
  Orestiinje. 
  

  

  The 
  remarkable 
  genus 
  Orestias 
  includes 
  about 
  twelve 
  

   species 
  from 
  elevated 
  lakes 
  in 
  the 
  Andes 
  of 
  Peru, 
  Bolivia, 
  

   and 
  Chile. 
  Externally 
  it 
  differs 
  from 
  Fundulus 
  chiefly 
  in 
  

   the 
  absence 
  of 
  pelvic 
  fins, 
  but 
  the 
  absence 
  of 
  parietalsand 
  the 
  

   forked 
  epipleurals 
  are 
  differences 
  of 
  considerable 
  importance.

  Characodontinje. 
  

  

  Differ 
  from 
  the 
  Fundulinie 
  especially 
  in 
  that 
  they 
  are 
  

   viviparous; 
  the 
  anal 
  tin 
  of 
  the 
  male 
  has 
  the 
  first 
  5 
  or 
  6 
  rays 
  

   short, 
  stiff 
  and 
  subequal,

  less 
  distinct 
  

   notch

  Grirardinichthys, 
  Charu- 
  

   coc/on, 
  with 
  seventeen 
  species, 
  almost 
  peculiar 
  to 
  the 
  system 
  

   of 
  the 
  Rio 
  Lerma 
  in 
  Mexico. 
  

  

  Zoogoneticus 
  has 
  the 
  jaws 
  and 
  teeth 
  of 
  a 
  Fundulus, 
  but 
  

   Charucodon 
  and 
  Glrardinichthys 
  connect 
  it 
  with 
  Goodea, 
  in 
  

   which 
  the 
  mouth 
  is 
  small, 
  the 
  teeth 
  are 
  movable, 
  compressed, 
  

   and 
  bicuspid, 
  and 
  the 
  rami 
  of 
  the 
  lower 
  jaw 
  are 
  loosely 
  

   connected

  5. 
  Jenynsiinjs. 
  

  

  Jenynsia, 
  with 
  three 
  or 
  four 
  species 
  from 
  the 
  La 
  Plata 
  

   and 
  Argentina, 
  has 
  the 
  osteological 
  characters 
  of 
  the 
  Fundu- 
  

   linie, 
  but 
  it 
  has 
  tricuspid 
  teeth 
  and 
  is 
  viviparous; 
  the 
  male 
  

   intromittent 
  organ 
  is 
  so 
  similar 
  to 
  that 
  of 
  Anableps 
  that 
  it 
  

   can 
  hardly 
  have 
  been 
  independently 
  evolved 
  in 
  the 
  two 
  

   genera. 
  As 
  noted 
  by 
  Garman, 
  the 
  males 
  of 
  denynsia 
  are 
  

   " 
  rights 
  and 
  lefts," 
  i. 
  e. 
  the 
  intromittent 
  organ 
  is 
  more 
  easily
