NOTES AND MEMORANDA. 
Eecently I observed a pair of conjoined individuals of Euglypha 
alveolata, which in their procedure appeared to coincide with the mode 
of multiplication of Chlamydoplirys stercorea as described by Cienkowski. 
One of the Euglyphce wsiS one-seventh of a millimetre long (0-14 mm. 
long, 0-068 mm. in the short diameter), and had four long spines 
diverging from the fundus of the test. This was replete with the 
contents, including the usual large nucleus; and it presented no 
perceptible interval between the mass of sarcode and the interior 
surface of the test. The sarcode was mingled throughout with 
particles of food, and also included a large Navicula. The food 
was not collected in balls contained in vacuoles, but was diffused 
through the sarcode from the mouth to the fundus of the test, impart- 
ing to it a brownish hue. The globular nucleus measures of a 
millimetre. 
Closely adherent to the mouth of the larger or parent Euglypha 
was the smaller or younger one, little more than half the size of the 
parent (measuring 0 • 08 mm. long and 0 ' 06 mm. wide). The young 
Euglypha had the fundus somewhat abruptly narrowed and acute, and 
projecting from it the same number of spines as in the parent test. 
The peculiar structure of the test was apparent, but appeared less 
extended or unfolded. The contents filled the test, and consisted of 
clear, colourless, finely granular protoplasm, without any mixture of 
food, and without a nucleus. 
Such was the appearance of the conjoined Euglyphce parent and 
offspring at the commencement of the observation at 6J o’clock in the 
morning. 
Closely watching the pair, the young Euglypha was noticed slowly 
to enlarge, and the brownish matter of the parent sarcode gently flowed 
into and became gradually diffused with the previously clear, colourless 
sarcode of the child. The fundus of the latter extended and became 
obtusely rounded, like that of the parent. The large nucleus of this 
disappeared or became so completely obscured as not to be visible. 
For some time there was no further very perceptible change within 
either test. 
An hour from the commencement of the observation the young 
Euglypha had nearly acquired the size, shape, and appearance of the 
parent, and it measured 0 • 112 mm. long and 0*064 mm. broad. Now 
commenced an active circulation, a cyclosis, of the contents of the two 
tests, resulting in a thorough admixture. The sarcode flowed con- 
tinuously from the parent on one side through the mouths into the child, 
and back again on the other side. Both tests were replete with one 
continuous mass of brown granular sarcode without nucleus or con- 
tractile vesicles, but with the Navicula which remained within the 
parent. During the circulation of the sarcode, two of the spines with 
the circular scale at their base became detached from the young 
Euglypha. The circulation ceased. At 74 o’clock I first observed 
the appearance of a contractile vesicle, 0-016 mm. in diameter, at 
the fundus of both animals. The vesicle collapsed and reappeared in 
two, three, or four, each again successively collapsing. With the 
appearance of the contracting vesicles the contiguous sarcode began
