Although  examples  of  only  eleven  species,  referable  to  5  genera, 
were  obtained  by  Dr.  Max  Weber,  no  less  than  4  of  these  prove 
to  be  undescribed  —  a  percentage  of  new  forms  which  is  certainly  large. 
Of  the  Sumatra  species  one  only  is  new  i.  e.  Ghaerilus  cavernicola. 
This  was  obtained  from  a  cavern  and  might  well  have  been  overlooked 
by  any  collector.  Of  the  others,  Hormurus  australasiae  is  found  wi- 
dely distributed  over  the  whole  of  the  region  ;  Isometrus  flavimanus 
was  previously  taken  by  Sig.  Beccari,  and  was  characterised  only 
three  years  ago  by  Dr.  Thorell,  while  Palamnœus  spinifer,  if  cor- 
rectly identified,  is  new  to  the  island. 
From  Java  likewise  only  one  new  species  i.  e.  Isometrus  formosus, 
was  brought.  Upon  this  discovery,  however,  Dr.  Max  Weber  is  espe- 
cially to  be  congratulated.  For  it  is  surprising  that  none  of  his  pre- 
decessors at  Buitenzorg  appear  to  have  seen  this  pretty  scorpion, 
which,  judging  from  the  numbers  that  were  brought  to  Europe,  seems 
to  be  tolerably  common.  With  the  exception  of  Ghaerilus  variegatus, 
which  is  apparently  somewhat  rare ,  the  other  Ja  van  species  i.  e.  Scor- 
pio indicus  and  Isometrus  maculatus  are  well-known  forms. 
In  Celebes  the  only  two  species  taken  on  the  mainland  —  at  Luwu 
—  are  new.  These  I  have  called  Hormurus  weberi  and  Ghaerilus  cele- 
bensis.  The  two  —  namely  Isometrus  mucronatus  and  Hormurus  aus- 
tralasiœ  —  collected  on  the  Island  of  Saleyer  are  wide-spread  species.  Both 
of  them  occurred  also  in  Flores,  from  whence  nothing  new  was  obtained.
