Based on the 1956-1989 index compiled by RICHARD FFRENCH
From 1965 the journal has been published biennially. In 1977 for the
first time the title carried both years of the two year span thus: Journal
of The Trinidad and Tobago Field Naturalists' Club 1977 - 1978. However,
the 1979 -1980 issue was wrongly titled 1978 - 1979 so there is no issue
titled 1979 - 1980. In the index the dates given refer to the first of
the two years in the title even though the actual dates of publication
may have slipped into the second year.
