JProtJiallus of Gleiehinia rupestris, with antheridia, was shown 

 by Dr. Moore. This formed a very pretty object viewed with a 

 \ in. objective, the long narrow prothallus being of a beautiful 

 vivid green colour, contrasting well with the brown antheridia. 



Test of a new Species of Euglypha, exhibited. — Mr. Archer 

 showed some examples of the test of a Ehizopod a priori to be 

 referred to Euglypha as a new species. He regretted ho had not 

 observed the living examples. It was somewhat irregular in 

 figure, but of a generally broadly subfusiform figure, truncated 

 in front, and somewhat drawn out posteriorly and bluntly rounded, 

 quite hyaline, the facetted appearance very difficult to make out. 

 There is no other Euglypha attenuated behind, all the species 

 being broadly and pretty equally rounded. Of course, without 

 seeing the living animal, one could not feel positive as to the cor- 

 rect location o£ this form in the genus Euglypha ; but there could, 

 probably, be very little doubt about it. The test, however, 

 appeared to be of, seemingly, a more yielding character than that 

 of an ordinary member of this genus, say E. compressa or 

 E. alveolata. Mr. Archer would meantime name this form 

 Euglypha sacciformis.
