des Chlorophylls bei Thieren. Arch. Anat. Phys. 1882, pp. 125-150, 
pi. 
The import and relationship of the chlorophyllaceous corpuscles, which 
impart a characteristic green hue to Hydra , Spongilla , and various 
Infusoria , such as Stentor polymorplius and Paramcecium bursarium, are fully 
discussed, and maintained by Brandt to represent an independent endo- 
parasitic group of unicellular Algae, for which he proposes the new generic 
titlo of Zoochlorella. A like significance is applied to the “yellow cor- 
puscles” of various Jiadiolaria, and which are distinguished by the generic 
name of Zooxanthella.

This volume does not embody the results of original investigation, 
but is an excellent compilation, based upon the published works and 
separate papers of other specialists, whoso figures and classificatory sys- 
tems are reproduced throughout the treatise. In this manner, Hmckel’s 
system and illustrations are chiefly associated with the Monera ; those of 
Greeff, E. Schulze, and Biitschli with the Amcebina ; Hertwig and Lesser, 
Carpenter, and Brady with the Foraminifera ; Hertwig and Lesser and 
Haeckel with Radiolaria ; Schneider with the Gregarina ; and Stein 
and Saville-Kent with the Infusoria.

New types described : — Wagneria mereschkowslcii, g. & sp. nn. of 
Protista , somewhat between Ilccclcelina and Glathrulina ; a colourless 
form of Labyrinthula , found within the dead cells of Pylaicella and other 
Phaeosporous Algae ; a Moneron, Gobiella borealis , g. & sp. nil., closely 
allied to Vampyrella and the following Flagellata : — Multicilia marina , 
g. & sp. nn., having a protoplasmic body of variable contour, desti- 
tute of nucleus or contractile vesicle, and possessing several flagella ; 
Exuviaclla marina , g. & sp. nn., having an ovum-shaped body, flattened 
horizontally on its upper surface, diversified by one or two round, shield- 
like markings, and bearing two flagella ; and Drepanidium boreale , sp. n., 
with a spherical body, prolonged anteriorly into a curved beak, which gives 
origin to a simple flagellum.

A careful investigation of the circumstances connected with the per- 
ception of light and colour by the lowest organisms has resulted in his 
attributing their sensitiveness of light to three principal modes or pro- 
cesses, viz., 1. Directly by modification of the interchange of gases,
