seum  of  Trinidad  (Assuncion)  I  saw  a  rattle¬ 
snake,  belonging  to  the  type  of  Northern 
Brasil,  and  some  Lachesis,  of  which  a  few  were 
like  N.  Neuwiedii  and  others  more  like  the  spe¬ 
cies  inapropriately  called  L.  cutiara.  There 
were  also  several  species  of  Elaps. 
PISCES :  On  the  upper  Paraná  we  only 
saw  a  few  fishes  which  were  caught  on  hooks 
during  our  excursions.  Besides  a  fine  Suruby 
there  were  a  few  dourados,  pacús  and  matrin - 
chem.  A  live  specimen  of  Lepidosiren  para¬ 
doxus  was  seen  near  Assuncion  where  it  is 
not  uncommon.  Its  native  name  is  Piram¬ 
boia. 
CRUSTACEA  :  Just  below  the  Salto 
de  Guayra,  or  “das  Sete  Quedas”  we  found 
some  Phyllopoda  in  active  parthenogenic  repro¬ 
duction,  in  two  pools  of  rainwater.  They 
belonged  to  the  genus  Eulimnadia  ;  the  spe¬ 
cies  may  be  brasiliensis  SARS  ;  at  any  rate 
the  differences  seemed  too  slight  to  distinguish 
a  new  species  in  this  somewhat  variable 
group.  Their  shells  were  covered  with  minu¬ 
te  threadlike  algae  and  the  usual  infusoria 
found  on  aquatic  animals.  Phyllopoda  were 
again  found  in  shallow  places  of  lake  Ipaca- 
rahy  and  determined  as  Estheria  His- 
lopi  BAIRD.  In  the  plankton  of  the  same  lake 
we  found  three  kinds  of  Cladocera ,  previ¬ 
ously  observed  by  ANIDITS,  and  determined 
by  DADAY  as  Diaphanosoma  brachyura 
LIEVIN,  Ceriodaphnia  cornuta  SARS,  and 
Bosmina  longirostris  LEYDIG.  There  was 
also  a  Copepod,  Diaptomus  conifer  SARS,  ac¬ 
cording  to  DADAY.  All  these  species  are 
also  found  in  Europe. 
INSECTA  :  To  the  entomological  notes 
given  above,  I  would  add  that,  in  Iguassu  we 
received  a  fine  Fulgora  (vulgo Jequitiranaboia)i 
of  the  species  found  in  São  Paulo  and  Rio; 
also  a  fine  specimen  of  Anoplocems  armilla- 
tus,  ( Prionidae ),  one  of  the  largest  beetles 
known.  In  BERTONI’S  collection  I  found  a 
specimen  of  Cuterebra  Schrnalzi ,  first  des¬ 
cribed  by  me  from  specimens  collected  in 
Santa  Catharina. 
The  shores  of  the  upper  Paraná  are  en¬ 
tirely  covered  with  woods.  At  the  riverside 
there  are  many  Cecropias,  a  series  of  large 
ficus  and  numerous  leguminosae.  Bamboos 
are  plentiful  and  a  giant  species  often  grows 
higher  than  the  surrounding  trees.  Larger 
and  smaller  creepers  form  real  curtains 
hiding  the  roots  and  stems  of  the  trees. 
At  the  waters  edge  there  is  often  a  conti- 
nous  fringe  of  Eichhornia  tufts.  They  are  some¬ 
times  swept  away  by  the  currents  and  form 
tloating  islands,  known  as  Camalotes.  In 
some  places  grasses  take  their  place.  Where 
there  are  cliffs  Cuphea  melvilla  may  be  found 
beneath,  while  the  rocks  are  covered  by  cactus 
and  bromeliaceous  plants. 
In  the  midst  of  all  this  foliage  few  blos¬ 
soms  are  seen.  We  noted  a  few  flowering 
Cassia  and  Inga  trees  and  Bignoniaceae  with 
white,  yellow,  pink  and  purple  blossoms. 
On  the  rocks  at  and  in  the  Iguassu  falls 
we  only  saw  a  large  and  conspicuous  Graminea. 
At  the  mouth  of  the  Iguassu  and  lower 
down,  a  Croton  with  long  inflorescences 
was  very  abundant  on  the  riverside;  it  alter¬ 
nated  with  Sapindaceae  and  Saramby.  Green 
bamboos  and  dead  Chusquea  stems  were 
also  plentiful.  This  vegetation  continued  till 
near  Encarnación,  being  only  interrupted  by 
artificial  clearings. 
A  creeper  looking  like  Mesechites  sul- 
phurea  was  fcund  near  Porto  Bandeira  and 
seen  again  at  Encarnación,  together  with 
another  apocynaceous  plant  with  white  flo¬ 
wers;  these  had  a  long  and  narrow  tube  and 
opened  only  at  night. 
In  the  campo  near  Encarnación  1  saw 
several  plants  new  to  me,  for  instance  two 
Verbenae,  one  of  which  had  red  flowers 
another  interesting  Verbenacea,  a  conspicuous 
blue  Labiata  and  an  Ipomoea  (  ?  malva- 
cea).  An  Eryngium  was  plentiful,  also  Mimo¬ 
sa  pudica,  an  Angelonia  and  other  plants  be¬ 
longing  to  to  the  Scrophulariciceae. 
The  flora  was  the  same  till  Assuncion. 
There  we  found  also  Ipomoea  fistulosa  in 
moist  places,  while  in  the  water  I  noticed
