the mouth; but they are much more slender and more repeatedly 
branched than in any Difflugia which I have seen. By means 
of these organs the animals pull themselves along, when lying 
upon their side, and they also creep by means of them, with the 
mouth downwards, moving onwards with a slow gliding motion 
like that of a Difflugia. 
Besides the heterogeneous collection of matters which these 
animals swallow, and which can be seen distinctly with all the 
forms and colors through the transparent exterior, there is also in 
most specimens a considerable number of small globules scattered 
without order, whose nature is very doubtful, for as yet there is 
no proof whether they are ova, oil drops, or something else. 
When these creatures have swallowed bits of fibres which 
have been dyed of various colors, the reds, blues, scarlets, &c. 0 
these filaments may be distinctly perceived through the sides 
of the animal, but the spectacle becomes still more curious 
when seen by polarized light, when the particles of quartz, 
ac. contained within these creatures also display their gor- 
animals, a distinct blue color was often seen all over the surface 
of many of the grains of sand in their stomach. The starch 
giving rise to this color was doubtless derived from bits of boiled 
beans and potatoes which had occasionally been introduced ito 
the aquarium as food for other animalecules. Another fact which 
appears to show that the sand, &c. is not swallowed merely t0 
increase the absorbing surface, as Dujardin suggests may be the 
; i d are 
case in Amoeba, is that these particles of san 
bodies are received, is a true stomach, and they therefore mabi- 
festly cannot be considered as polygastric animals. As tot @ po

that they belong to the Infusorial Rhizopoda of Dujardin,
