  On 
  some 
  new 
  Genera

  Fossil 
  Fishes.

  Amongst 
  the 
  fossil 
  Fishes 
  of 
  the 
  Neocomian 
  strata 
  of 
  Comes, 
  near 
  

   Gorizia, 
  Professor 
  Kner 
  has 
  recently 
  discovered 
  the 
  types 
  of 
  two 
  

   new 
  genera. 
  One 
  of 
  them, 
  Amiurus 
  pretiosus, 
  is 
  characterized 
  by 
  

   the 
  presence 
  of 
  an 
  intercalar 
  caudal 
  vertebra, 
  and 
  is 
  therefore 
  nearly 
  

   related 
  to 
  the 
  genus 
  Amia, 
  which 
  still 
  exists 
  in 
  North 
  America. 
  The 
  

   other, 
  Scombroclupea 
  pinnata, 
  has 
  the 
  conformation 
  of 
  the 
  mouth, 
  

   the 
  characters 
  of 
  the 
  scales, 
  and 
  the 
  ventral 
  carinas 
  characteristic 
  of 
  

   the 
  family 
  of 
  the 
  Clupeidce, 
  while 
  the 
  presence 
  of 
  "pinnulae" 
  be- 
  

   hind 
  the 
  anal 
  fin 
  shows 
  its 
  close 
  relationship 
  to 
  the 
  Scomberoidce. 
  A 
  

   Gadoid 
  related 
  to 
  the 
  genus 
  Brosmius 
  has 
  also 
  been 
  found, 
  with 
  other 
  

   fossil 
  Fishes, 
  in 
  the 
  Tertiaries 
  of 
  Pod 
  Sused 
  (Croatia).

  On 
  the 
  Terrestrial 
  Faun^j 
  of 
  the 
  Vienna 
  Basin.

  Prof. 
  Suess.

  The 
  careful 
  study 
  of 
  the 
  aquatic 
  faunas 
  within 
  this 
  Basin 
  has 
  

   enabled 
  the 
  author 
  to 
  show 
  that 
  local 
  freshwater 
  deposits 
  have 
  been 
  

   followed 
  first 
  by 
  marine, 
  then 
  by 
  brackish 
  deposits, 
  and 
  that 
  the 
  

   whole 
  series 
  has 
  been 
  ended 
  by 
  the 
  deposition 
  of 
  lacustrine 
  sedi- 
  

   ments. 
  The 
  remains 
  of 
  Mastodons, 
  Dinotheria, 
  and 
  other 
  Mam- 
  

   mals, 
  as 
  Horses, 
  Pigs, 
  and 
  Tapirs, 
  buried 
  in 
  the 
  first 
  three 
  of 
  the 
  

   above-named 
  deposits, 
  are 
  indicative 
  of 
  an 
  unchanged 
  association 
  of 
  

   genera, 
  and 
  even 
  species, 
  during 
  the 
  whole 
  period. 
  The 
  terrestrial 
  

   fauna 
  of 
  the 
  lacustrine 
  epoch, 
  although 
  of 
  the 
  same 
  general 
  character 
  

   as 
  that 
  of 
  the 
  preceding 
  periods, 
  is 
  yet 
  characterized 
  by 
  notable 
  specific 
  

   differences. 
  The 
  first 
  of 
  these 
  terrestrial 
  faunae 
  is 
  identical 
  with 
  

   those 
  of 
  Sansons, 
  Georgensgemiind, 
  Oeningen, 
  &c. 
  ; 
  it 
  may 
  have 
  be- 
  

   gun 
  simultaneously 
  with 
  the 
  formation 
  of 
  the 
  strata 
  of 
  the 
  Vienna 
  

   Basin, 
  and 
  so 
  have 
  ended 
  with 
  the 
  great 
  upheaval 
  of 
  the 
  Tertiaries, 
  

   the 
  traces 
  of 
  which 
  are 
  visible 
  in 
  Switzerland. 
  The 
  second 
  terres- 
  

   trial 
  fauna 
  of 
  the 
  Vienna 
  Basin 
  corresponds 
  with 
  those 
  of 
  Eppels- 
  

   heim, 
  Athens, 
  &c. 
  A 
  fauna 
  of 
  still 
  later 
  date 
  than 
  this, 
  evidences 
  

   of 
  which 
  occur 
  in 
  the 
  Val 
  d'Arno, 
  near 
  Florence, 
  has 
  not 
  yet 
  been 
  

   traced 
  within 
  the 
  area 
  of 
  the 
  Vienna 
  Basin 
  ; 
  nor 
  is 
  its 
  existence 
  there 
  

   very 
  probable, 
  as 
  stratigraphical 
  facts 
  prove 
  that 
  the 
  extent 
  of 
  dry 
  

   land 
  which 
  then 
  existed 
  in 
  that 
  area 
  was 
  too 
  considerable 
  to 
  have 
  

   left 
  any 
  space 
  for 
  notable 
  aqueous 
  deposits. 
  The 
  last 
  terrestrial 
  

   fauna 
  of 
  the 
  Vienna 
  Basin, 
  characterized 
  by 
  the 
  remains 
  of 
  Elephas 
  

   primigenius 
  and 
  Rhinoceros 
  tichorhinus, 
  as 
  well 
  as 
  (in 
  contempora- 
  

   neous 
  sediments) 
  Reindeer 
  and 
  Musk-ox, 
  is 
  of 
  "Diluvial" 
  age.
