The sea had the same appearance as on the previous day, and the nets from the 
surface were covered with slime. All the organisms noted yesterday were observed, 
CtenophonB being more numerous, while Echinoderm larvae and Crustacean larvae were 
very abundant, including the larvae of Gnathophausia zoea (?). Nemerteans were also 
present. 
Willemoes-Suhm writes : “ There was a great abundance of surface animals from 
80 fathoms, among which were the Zoea stages (?) of a Gnathophausia taken in the 
trawl. This would be very important as regards the systematic position of Gnathophausia, 
for the Lophogastridae, to which it is most nearly allied, undergo the Mysid metamorphosis, 
whereas the only Schizopods undergoing the Zoea stage are the Euphausidae, to which 
(Jnnthophnvsia is allied by the presence of accessory eyes on the maxillae ; Gnathophausia 
would therefore represent a very remarkable link between the two families.” 
The Challenger remained at Samboangan from 8.50 p.m. on October 23 till 6 a.m. on 
October 26.

MdioHnu, CristeUaria ), which may have been washed up from the bottom, along with 
part" of the stems of Hydroida and other things. There were besides: — Globigerina, 
(Jrbulina, Iv hinoderm larvae, Sabcllid larvae with siliceous tubes, many Zoea) and 
Nauplii, Ptcropoda and other small shells.
