HALIPHTSEMA. 37 



tered in tlie protoplasm are an immense number of 

 vesicular bodies averaging TyVoth inch in diameter, the 

 walls of which are thick and their contents granular or 

 else hyaline. Mr. Lankester suggests that these may 

 be called " vesicular nuclei." At the basal portion of 

 the core were egg-like bodies of protoplasm of much 

 larger size than the vesicular nuclei, varying from the 

 TiWth t the -scToth of an inch in diameter. In no 

 part of the body-substance could he find " evidence of 

 any axial cavity comparable to the enteron of higher 

 animals, nor the slightest trace of a breaking up of the 

 protoplasm into areas or units corresponding to cells, 

 with the exception of the egg-like bodies of the ante- 

 terior region ;" and the whole organisation points to 

 its relationship to the Foraminifera. 



Dr. K. Mobius is a third witness. He has confirmed 

 the observations of Kent and Lankester from the 

 examination of living specimens procured at the 

 Mauritius, and placed the genus among the Forami- 

 nifera. 



Mr. H. B. Brady, in his recent observations of classi- 

 fication of the Foraminifera in " Notes on some of the 

 Keticularian Rhizopoda of the ' Challenger ' Expedi- 

 tion " (' Quart. Jour. Mic. Sci.,' N. S., vol. xxi, 1880, 

 p. 13), has placed Haliphysema together with my genera 

 Technitella and Marsipella in the Family Astrorhizidce ; 

 and here it appears to me, according to our present 

 knowledge, is its most proper position. 



Although, however, Halipliijsema would seem to have 

 with our present knowledge no proper locus standi in 

 the present volume, it is right that it should be left 

 here in deference to what were Dr. Bowerbank's views 

 to the time of his death.
