Lec. {Diffliigia) spiralis Ehrbg., Fig. 12. 

 Euglypha Duj. 



Shell of round, oblique rows of plates, whose edges 

 cross to make hexagonal areas. Shell spherical to pear- 

 shaped. Spines frequently present. Mouth surrounded 

 by regular teeth. Body differentiated into a finely granu- 

 lar posterior portion and a coarsely granulated anterior 

 portion. Pseudopodia fine and frequently branching. 

 Eiig. alreolafa Duj., Fig. 24. 

 Cyphoderia Schlumbg. 



Shell retort-formed, with an oblique opening, composed 

 of five six-sided plates. Body differentiated into twq di- 

 visions, the anterior containing the vacuole and the pos- 

 terior the nucleus. 

 Cy. am pill I a Ehrbg., Fig. 15. 

 Microgromia H. & L. 



Usually united in colonies. Shell colorless, flask- 

 formed, with short neck. Pseudopodic openings slightly 

 to one side. Body incompletely filling the shell. Base 

 of pseudopodia slightly lateral, with contractile vacuole 

 at its base. Pseudopodia delicate, anastomosing, with 

 streaming granules. Commonly forming colonies. 

 Fig. 21 is, with some doubt, referred to this genus. 

 Pamphagus Bai. (Lecythiiini, H. and L.) 



Much like Microgromia. Shell delicate, flexible, and 

 lying closely upon the body. Body not evidently divided 

 into two regions. Pseudopodia delicate, without granules. 

 Pam. (Lecythium) hyalinnm H. & L., Fig. 30. 

 Diplophrys Barker. 



Shell spherical to ellipsoidal, with two pseudopodic 

 openings, not exactly in the body axis. A nucleus and 

 many contractile vacuoles present. Usually with one 

 large, or with two or more small yellow to red fat glob- 

 ules. Pseudopodia in two groups, delicate, slightly 

 branched, and not anastomosing.
