This Bulletin is a continuation of Bulletin No. 4 issued from this Institute as a
Supplement (for the 1900-1930 period) to the ‘Partial Bibliography of the Indian Ocean’
brought out by the U. S. Program in Biology in 1962. In spite of various handicaps my
colleagues have managed to bring together as many relevant references as possible for
the 1931-1961 period, which did not find a place in the ‘Partial Bibliography’. There
are in all 2682 references of which the greater part comes under fishes (827), crustaceans
(418) and molluscs (293).
The preparation of the Bulletin was undertaken at my suggestion by Messrs. R.
S. Lal Mohan, D.B. James and K.K. Appukuttan who completed the same without
prejudice to their routine work. It is needless to say that they had sacrificed a great
deal of their spare time for this purpose and gives me great pleasure to record my
sincere thanks and appreciation for their high sense of responsibility, co-operative
spirit and devotion to duty. My thanks are also due to other members of the staff who
in various ways helped in the completion of the Bulletin
