Amoeba terricola , Penard (335). — Description of the integument of Cochlio- 
podium pellucidum , Faur£-Fremiet (138). — Modifications in form and 
constitution of the shell (“ house f> ) of Difflugia , Reukauf (374).

of various Lagenidce, as characters indicating senescence, Cushman (96). 
Form- variation in the shells of different Peridinida described and com- 
pared, Entz (122). 
Observations on the comparative form and morphology of the Radio- 
larian (Tripylarian) skeleton, in relation to function and environment ; 
developmental considerations, Haoker (169 & 170).

(b) Nucleus and cytoplasm: — 
Structure of living protoplasm, as exemplified by various Protozoa, 
Gineste (158). — On the minute structure of protoplasm, as seen among 
Protozoa ; hyaloplasm, the primary plasm, consists of “ tagmas ” or 
granular substance, and an intertagmal lipoid substance, the “ Arboit- 
substanz ” ; there is a specific living substance, and the tagmas play a 
directive role in relation to the metabolism, Schneider (415).
