ANATOMY AND PHYSIOLOGY.

Folin (30) describes a branching, tubular, submembranous marine 
Rhizopod belonging to the Pseudarkysice , on which he founds the new 
genus Amphiexis. He also makes a new genus, Litliozoa , for a Rhizopod 
having a pebble-like test formed of a porcellanous paste, including 
foreign particles. 
Kiinstler (57) describes a remarkable Rhizopod, Dumontici oqiheliarum, 
g. & sp. nn., parasitic within the body cavity of various species of the 
Polychsete -Ophelia. The naked protoplasmic body is usually bilobed and 
produced into band-like pseudopodia. The denser endoplasm contains a 
cylindrical cuticular (chitinous) elongated tube which appears to enclose 
the nucleus. Reproduction occurs by the budding off of small vesicles 
from the axial tube, and finally the whole body breaks up into fragments, 
of which each possesses a bud from the axis. Kiinstler regards this ano¬ 
malous Protozoon as allied to the Radiolaria and Foraminifera. 
The construction of the shells of the Milioline Foraminifera is the 
subject of an important memoir by Munier-Chalmas and Schlumberger 
(103). These authors warn us that Foraminifera, externally similar, may 
differ considerably in their internal architecture : for example, B'doculina 
hulloides , d’Orb., from the Eocene of Paris, has nothing in common with 
the analogous living species; hence it is rash to assume the identity of 
Cretaceous and recent forms. After describing the symmetry of con¬ 
struction, the subject of dimorphism is treated. They find that each 
species is represented by two forms (a and b), which only differ inter¬ 
nally ; the form B is always recognizable by a very much smaller initial 
chamber (microsphere), followed or surrounded by more numerous 
chambers than in the corresponding form a. What they term “ initial 
polymorphism” is sometimes met with in the form a, and occurs in the 
post-embryonic period in the grouping of the first chambers, which take a 
bilocular, tnlocular, or quinquelocular arrangement round the mega¬ 
sphere ; this is freely illustrated for Idalina antiqua (d'Orb.). Perilocu- 
lina zitelli, g. & sp. nn. (p. 309), and Lacazina compressa (d’Orb.), are also 
fully described. 
Kiinstler (56) reviews the article by Zacharias (99) on the artificial 
production of very vibratile pseudopodia, recalling cilia or flagella. The 
latter concludes that the Flagellates are directly descended from the 
amoebiform Rhizopods. Although Kiinstler believes Zacharias’ pheno¬ 
mena to be abnormal, he considers cilia to be fine constant pseudopodia, 
but these organs are separated by a long evolution, and the bonds which 
unite them are perhaps less direct than appearances would lead us to 
believe. 
Barfurth confirms (pp. 314-321) the presence, and gives a figure 
(pi. xvi. fig. 13) of glycogen in Opalina ranarum ; Arch. mikr. Anat. xxv. 
Biitschli (12) confirms his previous investigations on glycogen (or 
paraglycogen) in Gregarince , which were recently called into question by 
Frenzel (34) ; he also finds a glycogenous substance in the Infusoria , 
Nyctotherus ovalis and Strombidinm. 
By three experiments Maupas (65) proves that true glycogen occurs in 
Paramcecium aurelia, confirming the discovery of Certes [cf. Zool. Rec. 
xvi. Prot. p. 3].
