Willemocs-Suhm writes: “The bottom fauna of the Arafura Sea is rather poor; 
there are no large shells nor Crustacea. Corals and fishes seem to be richly developed, 
and to have an Indian facies. Among the animals obtained I found a Gephyrean, which 
i- of great interest tx me, and the anatomy of which I closely examined. Its total 
length was 62'5 mm., width 23 mm., length of proboscis 12*5 mm., length of ovaria
