Loc. South coast of Devon, Budleigh-Salterton. 
Obs. Of this Rhizopod I have only found two specimens, one a 
little broader and shorter than the other. It strictly agrees with 
Euglypha alveolata, as may be seen by my figure of the latter 
(Annals, ser. 2. vol. xviii. pl. 5. fig. 25), in the essential features 
of the genus, but differs from it specifically in its compressed 
form (after which it has been designated), its sutural edge, re- 
striction of the hairs to this line, and in the figure of the scales. 
Euglypha alveolata. P\. Il. fig. 17. 
The accompanying figure of this species is to show that it may 
possess at least twelve hairs scattered over the posterior part of 
the test, or in a variable number down to their complete ab- 
sence ; also to show that the body-scales of the specimens here 
found are circular and overlap each other, giving the area an hexa- 
gonal form, and not an oval one, as that of the scales of the 
specimens found in the island of Bombay, to the illustration of 
which I have just referred; further, that the pointed ends of 
the scales around the aperture present serrated edges under a 
high power, that is, under a 3th-of-an-inch object-glass.

Cyphoderia margaritacea, Schlum. PI. II. fig. 18. 
This, although extremely common here (south coast of Devon), 
I have never met with in the island of Bombay. It has been 
figured to show how far it agrees and how far it differs from 
Euglypha. The test varies in form occasionally by the presence 
of a diverticulum posteriorly, which is more or less extended, as 
in Difflugia acuminata, and which I have never seen in Euglypha. 
During progression, the test is inclined, corresponding with the 
oblique direction of the aperture, which, in all the testaceous 
Rhizopoda when in motion, is brought into parallelism with the 
plane on which they may be creeping, and thus determines the 
position of the test under these circumstances. The scales of 
the body are more or less regularly hexagonal and in juxta- 
position, but not denticulated (as in Huglypha) at the aperture, 
which, in Cyphoderia margaritacea, presents a beaded edge, e. 
But it is not until we come to the pseudopodia that we find any 
very marked difference between this genus and Huglypha, and 
here only in their length, branched condition, the rapidity with 
which they are projected (more resembling those of Trinema 
acinus, Duj.=Euglypha pleurostoma, Cart.), and the peculiar
