THE VOYAGE OF H.M.S. CHALLENGED 
Api S. 81' W., Banda S. 45° 30' W., and the left peak of Rozengain 8. 47 15' E. At 
1.30 p.m. the ship was steered in for the anchorage, passing between Pnlo Pisang and 
Tangong Boerong, and at 2.15 p.m. anchored in 7 fathoms, with the right extremity of 
Pulo Neira N. 35° E., Fort Nassau N. 5° W., and the left extremity of Gunung Api 
Island N. 86° W. 
The deposit at 2800 fathoms in the Banda Sea was a blue mud, without any traces 
of carbonate of lime or shells of pelagic Foraminifera. The deposits at lesser depths in 
the same region usually contained many Foraminifera in the surface layers, while the 
deeper layers, which were of a blue colour, contained very few. Glauconite was present 
in all the deposits, together with the usual mineral particles derived from continental 
land. In the trawling in 360 fathoms, close to the island of Banda, a Spirula, with the 
soft tissues preserved, was taken — the only one obtained during the cruise. It had 
possibly been disgorged from the stomach of some animal, perhaps a fish, as the epidermis 
was partially digested, as is the case in most specimens known.
