“This was an extremely curious fusion, or firm hanging- 
together (seen, however, only on one occasion) of two in- 
dividuals. The capsules only were here fused together by 
their margins, whilst the two body-masses remained free, and 
without any connexion. This latter was, however, brought 
about by a peculiar indirect way, by a commissure of clear 
yellow hyaline substance proceeding from one individual to 
the other, of which substance mention was made above as a 
pigment sometimes occurring in the contents. This com- 
missure originated on both sides, with a broad basis, taking 
up almost the one-half of the circumference of the inner 
body, giving the appearance as if it flowed out therefrom, 
and it formed at the place of union an isthmus (or bridge), 
passing through the hyaline capsule-substance. The question 
becomes (says the author) what significance is to be attributed 
to this remarkable object—whether it represents an individual 
just about to undergo self-fission, or an act of impregnation, 
described for other Rhizopoda under the name of Conjugation 
or Zygosis.” [Although meantime the author was not in a 
position to prove either the one or the other for want of 
further observation on the object, he gives his adhesion 
rather to the interpretation of the case he describes as one of 
zygosis, from his having observed the young forms of the 
animal, as previously mentioned, which are distinguished by 
the want of the outer hyaline capsule. From these and other 
reasons (the above described nature of the nucleus) the author 
thinks he is justified in attributing to this form “a sexual 
reproduction, or rather a development of a young brood in 
the interior of the mother-body, and not a propagation by 
fisson.’’| 
The foregoing recapitulation (expressed in the third 
person) presents the account given by Greeff of his type- 
form nearly in full. To make the data more complete, by 
which readers of the present communication can the better 
realize the generic idea of Amphizonella, in which my own 
new form seems to fit, I add in the same manner, but slightly 
contracted, all he has to say of the next form, called 
AMPHIZONELLA DIGITATA (Greeff.)! 
As a second representative of the same genus as the fore- 
going (i.e. A. violacea) the author points to the form named 
A, digitata, presenting, as he describes, the same characters of 
structure and movements—* that is, an universally closed
