PLATE XXXVI. 



EUGLYPHA CILIATA. 



Fig. 1. Broader lateral view of an individual. The sarcode partially occupying the shell, with 

 pseudopods projected, presenting a nucleus in the fundus, several contractile vesicles just below, and a 

 quantity of food yet lower. Fig. 2. Transverse section of the shell of the same. 700 diameters. 

 Sphagnum, Absecom, May, 1875. 



Fig. 3. An individual observed in the act of discharging an operculum which had closed the mouth 

 of the shell. Some dirt still occupies the neck of the latter. Found with the preceding. 



Fig. 4. Au individual also found with the former. The sarcode fills the shell, and contains side 

 by side the nucleus and a large vacuole. 



Fig. 5. Au individual, in which the sarcode, together with a thick laminated operculum, fills the 

 shell. Fig. 6. Section of the shell. 350 diameters. Sphagnum, Absecom, October, 1874. 



Fig. 7. Small individual, in which the sarcode is retracted from the mouth and nearly fills the 

 shell. Surrounding the position of the nucleus it exhibited a multitude of detached plates like those 

 composing the shell. 500 diameters. Sphagnum, Vineland,N. J., September, 1876. 



Fig. 8. Individual with sarcode filling the shell, which is closed by an operculum. Sphagnum, 

 Vineland, N. J., April, 1877. 500 diameters. 



Fig. 9. Individual, with sarcode nearly filling the shell. Scales at mouth of latter much thick- 

 ened. Fig. 10. Transverse section of the same shell with the mouth. Sphagnum, Swarthmore, Dela- 

 ware County, Pennsylvania, October, 1874. 



Figs. 11-13. Three views of an empty shell. Found with the former. 



Fig. 14. Small individual, from spring on Darby Creek, Delaware County, March, 1876. 



Fig. 15. Transverse or inferior view of a shell, with the mouth. 1,000 diameters 



Fig. 16. Hirsute variety of the shell. 500 diameters. Sphagnum of Absecom, N. J., October, 1874, 



Fig. 17. Another specimen of the same kind. Same locality. 



Fig. 18. A third specimen ; hirsute at the fundus. Same gathering as the preceding two. 



Fig. 19. Shell hirsute on the narrower sides. 700 diameters. Breadth of shell 0.052 mm. by 

 0.026 mm. Sphagnum, Absecom, N. J., October, 1874. 



Fig. 20. Hirsute shell. Fig. 21. Outline of the narrower side. 500 diameters. Sphagnum of 

 Absecom, September, 1874. 



Fig. 22. Fundus of an individual, in which the nucleus appeared to be enclosed in a membranous 

 cyst. 500 diameters. Sphagnum, Absecom, October, 1874. 



Fig. 23. A shell, entirely devoid of spines or hairs. 750 diameters. Absecom, October, 1874. 

 Breadth of the shell nearly double in one direction of the other.
