it digs its holes between and under the stones, the small (here) 
white sand halls dug up by it lying spread all over, very conspicuous 
among the black stones. Farther out, where the volcanic stones 
are much less numerous, and where a few centimeters of water 
may remain, covering the sand at low tide, the community of the 
Edwardsia's occurs, as at Saparoea and the Kei Islands, but here 
also were observed, in places, groups of fine Sabellids, their red 
tentacle crowns looking like beautiful flowers. 
The r/za/ass/a-meadows occupying the outer part of the flat were, 
as usual, inhabited by a very rich and varied fauna — Holothurians, 
Asterids, Molluscs (a. o. a small green Åkera-\\)^Q form, in colour 
80 closely resembling the Thalassia leaves, that it was very hard 
to discover) 5 but a feature which I have not observed in other 
places was the considerable number of mostly small specimens of 
Echinothrix calamaris (also some Salmacis) lying free among the 
leaves; otherwise these sea-urchins are, at daytime, mostly found 
under stones, where they hide themselves, together with the young 
Diadema's. The Tripneustes, which is more generally found moving 
free about also at daytime, covers itself with small stones, pieces 
of Thalassia leaves, algæ etc. and thus procures a concealment 
(perhaps also from the light). The number of small fishes occurring 
in these T/za/ass/a-meadows — mainly in the deeper part, where 
the leaves still float free also at low tide — is astonishingly great. 
A haul with a seine, for which I engaged the native fishermen, 
brought an overwhelming mass of mainly small forms or young 
fish — Teuthis, Zanclus, Mullus, Hemiramphus, Åulostoma etc. — 
a true orgy of colours! Using a seine in such a locality, where not 
only the dense Thalassia-grov/ih, but also stones and coral blocks 
will catch the net, presents considerable difficulties, of course; they 
are, however, easily overcome, the fishermen simply diving down 
and lifting the net over the hindrance, where it may have caught 
hold, all the while they are shouting and pulsing in the water with 
sticks in order to frighten the fishes away from the place, where 
the net is to be lifted. The same way of using a seine I have 
also observed in the West Indies. 
Most noteworthy among all the fishes of Banda is undoubtedly 
the “laweri”, the famous fish with the large luminous organ situated 
under the eyes, several specimens of which (the “laweri batoe ,
