Two rare monstrilloid copepods from the coastal waters of Bombay

Redescriptions of two species of monstrilloid copepod of the genus Cymbasoma I.C. Thompson, namely C. tropica (Wolfenden), a new record for Indian waters and C. longispinosum (Bourne) earlier described from Vizhiiyam, South Kerala Coast are given here based on specimens obtained from the plankton of the Bombay Coast.
