latter case they would perhaps represent a parasitic fungusy 

 certainly deviating from all at present known ; in the former 

 I do not know how to interpret them, except as urticating 

 organs, which would exhibit an extremely remarkable agree- 

 ment with the urticating organs of the Coelenterata. Although 

 I am inclined to the latter view, I would leave the decision to 

 further investigations, which should be directed especially to 

 the genesis of these bodies. If it should prove that these 

 structures are really urticating organs belonging to the Vor- 

 ticellan body, this would be of the greatest importance to our 

 knowledge of the structure of the Infusorian body, as these 

 urticating capsules, considering their perfect agreement with 

 those of the Coelenterata, would undoubtedly be developed, 

 like the latter, /row cells.

§ 1. Amongst the most enthusiastic observers and voluminous 

 writers on Foraminifera Dr. Ch. G. Ehrenberg stands pre- 

 eminent. By the end of the year 1838 he had reduced to 

 order the multitudinous specimens of recent and fossil Micro- 

 phytes and Microzoa which he had either gathered, witli Dr. 

 Hemprich, in the East or had received from numerous corre- 

 spondents. Among the results is the Tabular Classification* 

 of his BryoZOA [PolytJialamiaj Gymnocorw, Thallopoda, and 

 Bceleropodia), which, mingling Foraminifera and Polyzoa,
