"Animal  of  Ghssula  oakesi  from  llotuiig  (Oakes).  The  sole  of
the  foot  is  crossed  by  coarse  ridges,  there  is  a  very  distinct
peripodial  margian  (text-fig.  3  A).  The  genitalia  (figs.  8  B,  0,  I))
was  fairly  well  seen  in  one  specimen,  but  more  material  was  sadly
wanted.  The  hermaphrodite  duct  is  conspicuous  from  its  size  and
close  convolution,  bound  closely  together  at  its  junction  with  the
albumen  glai]d.  The  penis  is  very  short  with  a  short  stout  flagel-
lum  terminating  in  three  blunt  knots  ;  it  thus  dift'ers  from  what
1  have  been  able  to  see  in  other  species.  The  vas  deferens  is
given  off  from  near  the  head  of  the  penis,  the  spcrmatheca  was  not
seen."

"  This  species  (G.  oahcsi)  is  the  same  as  the  one  recorded  from
Rotung  as  G.  botelhis,  Bs.,  of  Southern  India  by  3Ir.  H.  B.  Preston
in  the  '  Records  of  the  Indian  Museum,'  vol.  viii.,  Nov.  1915,
p.  539;  it  is  a  bare  record,  in  any  case  remarkable  as  regards
range.  As  I  had  not  noticed  this  South  Indian  species  among  the
large  series  sent  me  from  the  Abor  Hills,  I  was  anxious  to  see  the
shells  which  had  gone  to  Calcutta.  Dr.  Annandale  very  kindly
sent  these  to  me  (October,  1916),  and  I  have  compared  them  with
specimens  of  Glessula  botelhis  in  the  Henry  Blanford  collection
from  the  Nilgiris,  with  the  result  that  I  cannot  conliim  Mr.  Pres-
ton's determination.  This  Abor  Glessula  (oal-esi)  is  decidedly
smaller  than  G.  hotellus,  and  not  so  tumid,  the  whorls  are  closer
wound,  the  outer  lip  is  much  more  thickened  than  in  bvtdlus,  tho
Lirger  shell.  I  have  compared  the  embryonic  whorls  and  made
enlarged  drawings  of  hotellus,  Nilgiris  (PI.  CXLIII.  fig.  1),  of
Mr.  Preston's  specimen  (PL  CXLIII.  fig.  3),  and  of  the  type
specimen  of  oakesi  (PL  CXLIII.  fig.  2)  ;  the  dift'erence  between
the  first  and  the  two  last  is  very  marked,  it  is  unmistakable."
