 (Plate LX, figs. 1-4.) 



Corycta radiata 

 BROWN in Scot. Natur. 1912, p. 109, pi. v, ff. 1-4. 



Test small, sac-like, composed of a transparent and 

 colourless chitinoid pellicle, bordered by a very thin, 

 flexible, transparent membrane ; the crown of the test 

 furnished at the margin with two concentric, circular 

 ridges and also seven or eight radial ones ; plasma not 

 completely filling the test, greyish, granular ; nucleus 

 single, containing a central nucleole; contractile 

 vacuoles one or more ; pseudopodia not observed.

Genus 15 c. PARMULINA Penard, 1902. 



Parmulina PENARD Faune Rhiz. Leman (1902), pp. 206- 

 207; and (amended) in Arch. Protist. XVII (1909), p. 

 286. 



Animal amoeba-like but invested with an ovoid test 

 of chitinous membrane covered with foreign particles ; 

 aperture uncovered but capable of being closed ; 

 plasma similar to that of an Amoeba, containing a 

 single nucleus and one or more contractile vesicles. 



This genus is very closely allied to Uiplocldamys and 

 somewhat similar to Microcori/cia. As first described 

 by Penard in 1902, the test of P. cyathus was defined 

 as hemispherical, but in 1909 the description was
