V. ovata. Cells from four to seven times as long as 

 broad. Sporangia oval, frequently of a golden colour, 

 usually solitary, but sometimes binary ; cells next the spo- 

 rangia inflated.

This is a very distinct species, as also a very beautiful ob- 

 ject under the microscope. There can be no doubt about the 

 synonyme of M. Leon le Clerc. 



16. VESICULIFERA CILIATA Hass. 

 Plate LII. Fig. 2. 



Char. Filaments smaller than those of V. pulchella, termi- 

 nated by long colourless cilia. Cells about three times as 

 long as broad. Sporangia oval, lodged in cells of the same 

 form. 

 Hal. Cheshunt: A. H. H. 



The presence of cilia on the extremities of the filaments 

 renders this a very remarkable species, and one by which it 

 may be readily recognized. There is an evident analogy 

 between the genera Vesiculifera and Bulbocho2te, and through 

 V. ciliata there would appear to be an easy transition from 

 the one to the other. 



17* VESICULIFERA DISSILIENS Hass. 

 Plate L. Fig. 7. 



Char. Filaments of considerable diameter. Cells scarcely so 

 long as broad. Sporangia circular, contained in inflated 

 cells of the same form, and which are usually solitary.
