and Globigerinae, an occasional Codonella, afew Thalassiothrix nitzschioides, 
a few Chaetoceras-horns, a very small Coscinodiscus, a small Ostracod, one 
half of a very small Lamellibranchiate-shell, rather many mineral particles ; 
oesophagus-contents of the same sea-bandeng; rather many Pleuro- 
sigma-like Naviculinae, a rather great quantity of Thalassiothrix nitzschioides, 
a few representatives of fine Chaetoceras-species among which Chaetoceras 
secundum, a number of long serrated horns of representatives of bigger 
Chaetoceras-species, a few Bacteriastrum’s, a few Rhizosolenia’s, a rather 
thick Schizophyceae-filament, a few remainders of vegetable tissue (of 
higher Algae?), some Rotalidae, an occasional Miliolid, an occasional Tex- 
tularid, an occasional Codonella, a very small shell-bearing Gastropod, a fair 
number of minute Lamellibranchiates, an occasional small Copepod, a 
Copepod-larva, some mineral particles. 
3. September 3rd 1919; sea-bandeng 93 cM. long exclusive of the 
caudal fin; intestinal tract empty, no recognizable remains of food to be 
found; stomach empty, no recognizable remains of food to be found. 
4. September 11th 1919; sea-bandeng, a little over 80 cM. long, not 
including the caudal fin; contents of the fore part of the oesophagus: a 
small quantity of fragments of vegetable tissue, presumably of higher Aigae 
(Phaeophyceae, Ulvaceae ?). 
5. October 14th 1919; contents of the stomach of a sea-bandeng: a 
fine brown ooze, which under the microscope proves to consist of: a 
very large number of Pleurosigma-like Naviculinae, a few Rotalidae, some 
vegetable detritus (of higher Algae?), some mineral particles; 
intestinal contents of the same sea-bandeng: a fine brown ooze, 
which under the microscope proves to consist of: a large number of shells 
of Pleurosigma-like and also Navicula-like Naviculinae, a fair number of 
Rotalidae, a few fragments of parenchymatous vegetable tissue (higher 
Algae?) an occasional small Copepod, some mineral particles. 
6. October 17th 1919; intestinal contents of a large sea-bandeng: 
some benthos')-Diatoms, a few Foramimifera, some Chaetoceras-horns, 
a minute Coscinodiscus. 
7. October 21st 1919; stomach contents of sea-bandeng; large 
quantities of benthos-Diatoms (Naviculinae) a few empty Raizosolenia- 
Shells, a number of Gammaridea in black dwelling-tubes, some mineral 
particles. 
8. November 10th 1919; sea-bandeng 76 cM. long, not including the 
caudal fin; contents of oesophagus: a quantity of small karyo-enteric Salpae. 
9. November 14th 1919; sea-bandeng; contents of intestine (just 
beyond the stomach): remainders of vegetable tissue in an advanced stage 
of digestion (higher Algae ?). 
How can the above data be summarized? 
1) benthos-Diatoms = Diatoms living on a firm substratum, in contradistinction 
to plankton-Diatoms.
