. The same; an example showing a pseudopodium expanded into a clavate form 
and enclosing some of the larger semi-opaque granules, like those in the interven- 
ing spaces of the conjoined psoudopodia of the three associated examples shown in 
Fig. 7 . - : 
The same; showing an example in which the body has undergone a-transverse 
self-fission, and in each portion a nucleus with its nucleolus is present, the upper 
segment giving off branched pseudopodia in the usual manner. 
. Difflugia carinata (sp. nov.), x 200. 
All the figures x 400, except fig. 12 x 200.

Polpys, seen from above, three expanded; from the side of the retracted polyps; 
which is seen in the lower part of the figure, between the two expanded 
polyps, will be found the lateral fold-like prolongation of the tube referred to 
in the text. 
. Polyps in different stages of expansion and retraction; at e the lateral fold-like 
prolongation is seen. 
. Mouth, with circular lip and four tentacles studded with spicules. 
. A section through tube and polyp, the latter fully retracted. 
. Lenticular spicules from the tentacles. 
. Fusiform spicules, plain and warty, from ectodermic layer between base of tenta- 
cles and edge of hard tube. 
. Warty fusiform spicules. 
. The same, gradually becoming coalesced, and forming a rough irregular network 
at one spot; in another becoming solidified.
