of Bombay, it is so restless, and its movements so rapid, that it 

 is difficult to get at its real form. 



Euglypha, Duj. 

 Euglypha spinosa, n. sp. PI. XII. fig. 13. 



Test. Oblong, rather wider in front than behind on the broad 

 side, compressed, wedge-shaped, convex anteriorly and poste- 

 riorly, translucent, covered with subcircular plates, which, over- 

 lapping each other, present a more or less irregularly cancellated 

 appearance (b). Aperture rimous, extending throughout the 

 anterior border. Ventral portion more or less inflated. Sides 

 and posterior extremity narrow, terminating in an angular ridge, 

 which behind, and for two-thirds of its length laterally, supports 

 a row of moveable spines based on fixed tubercles, like those of 

 Cidaris (cccc). Spines clavate, pointed at their free ends (c'). 



Animal. Sarcode containing fragments of incepted food and 

 granules anteriorly (/), behind which it is charged with granules 

 alone (g) ; and posterior to all is the nucleus (h). Pseudopodia 

 and contracting vesicles not seen, but probably the same as in 

 Euglypha alveolata, &c. 



Hab. Heath-bog water. 



Size. Length -rf-rst, breadth -a-^rth of an inch. 



Loc. Budleigh-Salterton, South Devon. 



Obs. I have only seen two or three specimens of this Rhizo- 

 pod; and, it being winter, the animal part in all was passive. 

 Thus the aperture was in all probability much more compressed 

 than during active life. The sarcode was retracted, and there 

 was a kind of diaphragm about halfway between it and the 

 anterior extremity. The most remarkable feature about it, next 

 to its wedge-like shape, is the presence of spines, which, in some 

 instances, lying across each other while the tubercles remained 

 fixed, showed that they were moveable, like those of the Echino- 

 dermata. Widely separated, however, as the latter are from the 

 Pthizopoda, still they have many points of resemblance in their 

 living state, and are frequently and almost exclusively associated 

 in a fossil one. 



Euglypha globosa, n. sp. PL XII. fig. 14. 



Test. Globular, with a short compressed wedge-shaped neck 

 and narrow aperture, which can be closed by the animal (a). 

 Globular portion translucent, covered with uniformly circular 

 scales, which are so arranged as to slightly overlap each other 

 hexagonally, and thus present a cancellated structure of the 

 most regular appearance. Neck studded with minute points, 

 perhaps minute scales. Supernumerary scales within the test 

 (ee).
