The need for a redescription of the little known Chaetognatha Sagitta bombayensis
Lele and Gae (1936) "first described from the Bombay Harbour and subsequently
recorded by Rao and Kelly (1962) from Lawsori's Bay, Waltair, is evident from the
recent review of 'Chaetognaths' by Alvarino (1965). George (1949, 1952)
considered S. bombayensis a synonym of S. robusta Doncaster (1903), but Rao and
Kelly (1962) have drawn attention to a few differences between these two species, at
the same time also recognising three stages of maturity which are inadequately described.
Apparently the types, one mature and two immature specimens, have not
been saved, as Lele and Gae (1936) do not mention of these being deposited in any
recognised collection. Hence, in November 1966 one of us (E.G.S.) made special
plankton collections from the Bombay Harbour using a half-metre ringnet of
No. 20 Swiss Silk Bolting cloth for obtaining topotypes of S. bombayensis to enable
a redescription of the species as well as for a taxonomical reappraisal of it. A
graded series of the specimens obtained has enabled us to recognise five stages of
maturity (including 0-stage) all of which are described and illustrated in this
account. The topotypes are deposited in the research collection of the Central
Marine Fisheries Research Institute, Mandapam Camp.
