Squamulina scopula”) at Budleigh-Salterton, and made the 
following observations :—“ On cutting off the branched head 
with a pair of scissors across the main stem, and placing it in 
a watch-glass, the truncated end soon after threw out a bunch 
of obliquely branching and anastomosing filaments or pseudo- 
podia, to the extent of a sixtieth of an inch long, allround, which 
continued retracting and extending themselves and exhibit- 
ing the granule-circulation, after the manner of the sarcode 
of the Foraminifera, for six hours, when the whole were gradu- 
ally withdrawn and did not reappear. Thus the Foramini- 
ferous character of Squamulina scopula and its branched 
variety is proved. I could not see any filaments projected 
from the head in any of the specimens; nor would it be easy 
to do so, as these probably entwine themselves about the 
spicules which are always raised up from the bottom of the 
water; but the truncated end of the stem lay on the watch- 
glass, over which it was easy to see the extended filaments 
with a one-inch compound power” *. 
Mr. Carter has also met with what he regards as another 
form of the same genus at Budleigh-Salterton. To this he 
has given the name Squamulina varians. It consists of a 
little rounded dome, commonly semiglobular, but varying 
much in shape, attached by its flat side to the fucus or other 
object on which it grows, having a test composed of colourless 
grains of quartz and sponge-spicules incorporated in a chiti- 
nous substance, with a slight admixture of calcareous parti- 
cles. The dome is furnished with an extended margin, 
projecting beyond the body of the test, and terminating in a 
thin edge, the basis of attachment of the organism being thus 
greater than the size of the dome itself. A single rounded 
aperture is situated either at the base or summit, or anywhere 
between the two, and this aperture is somewhat funnel-shaped, 
widening outwards. Size seldom exeeeding 1-30th of an inch 
in diameter. 
It is this Sguamulina varians which comes nearest in gene- 
ral form to Sguamulina levis, Schultze; but, besides other 
differences, while the test of Carter’s so-called Squamulina 
is arenaceous, that of the type of the genus is calcareous. 
Squamulina vartans is in general form very like the base 
of H. Tumanowiczit before the development of the column 
and clavate head ; but unless it be the immature stage of that 
or of an allied species, it cannot take its position with them 
in Haliphysema. 
But we have to consider the position of the type with refer-
