 In many specimens the cells are aggregated, forming con- 

 tinuous membranous expansions, with quite the aspect of a

 form, interspersed among the cells in the membraneous 

 variety.

 dolle many years ago to a genus of TTmbellif eras. Dr. Mueller suggests that the 

 synonymous term Bifrons might be substituted for the present genus.
