  In 
  the 
  last 
  Report 
  of 
  the 
  Zoological 
  Gardens 
  at 
  Giza, 
  near 
  Cairo, 
  by 
  

   the 
  Director, 
  Capt. 
  Stanley 
  S. 
  Flower, 
  there 
  are 
  some 
  interesting 
  notes 
  

   relating 
  to 
  the 
  prisoners 
  of 
  the 
  aquarium. 
  

  

  Fam. 
  Morjiyridje, 
  Gnathomenus 
  cyprinoides 
  (Anooma). 
  — 
  Though 
  in 
  

   a 
  state 
  of 
  nature 
  their 
  habits 
  are 
  apparently 
  nocturnal, 
  in 
  captivity 
  

   they 
  soon 
  learn 
  to 
  feed 
  by 
  daylight, 
  and 
  eagerly 
  devour 
  the 
  finely 
  

   chopped-up 
  earthworms 
  on 
  which 
  they 
  are 
  fed 
  daily. 
  

  

  Fam. 
  Characinidjs. 
  Hydrocyon 
  forskali 
  (Kelb-el-Bahr, 
  or 
  Dog 
  of 
  the 
  

   River). 
  — 
  The 
  Kelb-el-Bahr 
  is 
  very 
  active 
  and 
  voracious, 
  feeding 
  only 
  

   on 
  live 
  fisb, 
  such 
  as 
  Alestes, 
  which 
  it 
  pursues 
  and 
  captures 
  with 
  

   lightning-like 
  agility, 
  and 
  either 
  swallows 
  whole 
  or 
  bites 
  right 
  in 
  half, 
  

   swallowing 
  the 
  half 
  seized. 
  It 
  is 
  found 
  necessary 
  to 
  keep 
  a 
  lamp 
  

   burning 
  near 
  their 
  tanks 
  all 
  night, 
  as 
  if 
  left 
  in 
  complete 
  darkness 
  they 
  

   damage 
  themselves 
  swimming 
  violently 
  against 
  the 
  walls 
  of 
  the 
  tank, 
  

   but 
  with 
  a 
  glimmer 
  of 
  light 
  they 
  avoid 
  this. 
  

  

  Fam. 
  Silurid^:, 
  Clarias 
  lazera 
  (Armoot). 
  — 
  These 
  fishes 
  are 
  fed 
  on 
  

   raw 
  meat, 
  and 
  eat 
  large 
  quantities 
  of 
  it. 
  After 
  a 
  meal 
  the 
  distended 
  

   stomach 
  quite 
  alters 
  the 
  general 
  appearance 
  and 
  shape 
  of 
  the 
  fish. 
  

   With 
  a 
  sufficiency 
  of 
  food 
  a 
  crowd 
  of 
  individuals 
  will 
  live 
  amicably 
  

   together, 
  but 
  hunger 
  leads 
  to 
  internecine 
  warfare. 
  

  

  Fam. 
  Serranid^e, 
  Lates 
  niloticus 
  (Ishr, 
  or 
  Great 
  Nile 
  Perch). 
  — 
  One 
  

   of 
  the 
  most 
  noticeable 
  points 
  about 
  the 
  Ishr 
  is 
  its 
  gleaming 
  eyes, 
  which 
  

   in 
  some 
  lights 
  glow 
  red 
  like 
  dull 
  signal 
  lamps 
  ; 
  another 
  is 
  its 
  power 
  of 
  

   rapidly 
  changing 
  its 
  colour, 
  and 
  the 
  appearance 
  and 
  disappearance 
  of 
  

   dark 
  markings 
  all 
  over 
  the 
  sides 
  of 
  the 
  body 
  ; 
  further 
  observations 
  are 
  

   wanted 
  concerning 
  when 
  and 
  how 
  this 
  is 
  carried 
  out. 
  

  

  Mammals 
  in 
  captivity 
  seem 
  to 
  have 
  a 
  considerable 
  mortality. 
  

   Twenty 
  accidental 
  deaths 
  include 
  nine 
  Jackal 
  puppies 
  eaten 
  by 
  their 
  

   mothers, 
  a 
  Lion 
  cub 
  which 
  choked 
  itself 
  eating 
  a 
  piece 
  of 
  meat, 
  an 
  

   Angora 
  Goat 
  which 
  fell 
  into 
  a 
  canal 
  and 
  drowned, 
  and 
  several 
  animals 
  

   and 
  birds 
  which 
  met 
  their 
  deaths 
  fighting 
  their 
  companions 
  in 
  the 
  

   same 
  cages. 
  

  

  Among 
  other 
  deaths, 
  six 
  of 
  nine 
  Lemurs 
  died 
  of 
  dysentery 
  (ulcera- 
  

   tive 
  colitis) 
  between 
  Jan. 
  11th 
  and 
  Feb. 
  26th, 
  one 
  died 
  from 
  the 
  result
