 Leidy, 207, pi. xxxv., tigs. 2, 3, 6, 11, 12, 13, U, 15. This 

 is very common and may be obtained in abundance on 

 Sphagnum, in the Waterloo Swamps. 



Trinema, Dujardin. 

 Enchelys, Ehr., Infus., 1838, 132, Taf. ix., fig. 4 ; Leidy,

 It is very abundant near Shea's Creek and in the Waterloo

 localities given in this list. 



Heterophrys, Archer. 



19 Heterophrys sp. 1 I have on several occasions seen a species 



closely allied to, if not identical with, one figured by Leidy 

 on pi. xlvi., tigs. 7, 8, 9, 13. It existed in a pool of water 

 off Bunnerong Road, which is unfortunately now quite dry. 

 In the same place I found also a colourless gregarious 

 species resembling Raphidiophrys elegans, but much spialler 

 and destitute of silicious spicules. The pseudopodia are 

 highly sensitive and the creature retracts them somewhat 

 suddenly if disturbed. It also readily assumes an ameboid 

 form if subjected to pressure. I hope to re-examnie both 



Raphidiophrys, Archer. 



20 R. elegans, Hertwig and Lesser, Archiv. fiir Mik. Anat x^, 



1874; Leidy, F. Rhiz. N. Amer., 250, pi. xhi., figs. 1-b. 

 This species is not common. I have seen it from two 

 localities only, near Shea's Creek and in the stone quarry 

 Moore Park.
