PLATE XLVIII. 



BIOMYXA VAGANS. 250 diameters. 



Fig. 1. Large individual, containing many minute contractile vesicles together with a number of 

 Ciosteriunis. The larger circular spaces are vacant and were produced by the closing of meshes of the 

 protoplasmic net. The arrows indicate the course of the protoplasmic currents. From sphagnum, of 

 Absecom, New Jersey, collected in the autumn of 1874 and preserved in a glass case during the winter. 

 Observed March, 1875. 



Figs. 2, 8. Two successive views of a small individual, found with the former, and supposed to 

 bo a detached fragment. 



Figs. 4-6. Three successive views of an individual. Observed in the same sphagnum as the 

 former. 



Figs. 7-9. Three successive views of another individual. Also from the same sphagnum. 



Figs. 10-14. Five successive views of an individual. From sphagnum of Broad Mountain, Penn- 

 sylvania, September, 1870'. 



Figs. 15-17. Three successive views of an individual. From sphagnum of Atco, N. J., April, 1877. 



Figs. 18-20. Three successive views of an individual. It contained a distinct granular nucleus, 

 and is suspected to pertain to the same organism as the former specimens. Found with the preceding 

 in sphagnum of Atco, N. J. 



Fig. 21. Supposed to be a condition of Biomysa. It contains a nucleus, several contractile vesi- 

 cles, and numerous darkly defined granules. 



Figs. 22-25. Four successive views of another individual of the same kind. As first seen, fig. 2, 

 the creature discharged a large mass of excrementitious matter. 



The subjects of tigs. 21-25 were found, with many others of the same kind, together with multi- 

 tudes of minute desmids, in a clear gelatinoid substance, adherent to the glass case in which was pre- 

 served a 'arge bed of sphagnum, collected in the autumn at Absecom, N. J. April, 1877.
