arranged. One of the hindmost four is a gonidium of about 
49 » diameter. The others have segmented into four and eight 
cells. This points to the undivided gonidium being probably 
full-grown. The number of somatic cells was estimated to be 
about 1,000. 
Specimen 36.—The smallest coenobium with large gonidia 
is one measuring 213 by 220 » and presenting an anterior view. 
Its somatic cells were estimated to be 730. It contains eight 
gonidia that are about 42 » in diameter. 
An undated slide of material from near the same source as 
the preceding small form bears three that are figured herewith. 
They are: 
Specimen 37.—An asexual coenobium with eight gonidia that 
are all divided, two into 2 cells and the others into 8, 16, or 32 
cells, is shown in Plate 5, fig. 35. In the picture the coenobium 
measures 400 by 425 ». On the slide it measures only 328 by 
840 ». I would think the magnification to be wrongly stated 
but for the fact that the reproductive bodies are about the same 
size as shown in the picture. 
Specimen 38—An asexual coenobium with eight gonidia, 
shown in Plate 3, fig. 21, has about 1,600 somatic cells. 
Specimen 39.—The smallest specimen shown is the one shown 
in Plate 8, fig. 22. It measured 138 by 144 », and was estimated 
to have about 500 somatic cells. It has seven gonidia of about 
19 to 22 u. The apparent angularity of the cells in the photo- 
graph is an optical effect that is more marked on those that are 
out of focus, and probably due in part to the shadows of the 
cells of the farther side of the coenobium. 
A similar small form of the species was present in Pond Q 
in 1915. Some material taken from there on October 2 was 
stained with Bismarck brown, mounted in Venetian turpentine, 
and photographed. They all show considerable shrinkage and 
have shrunken further since the photographs were made. 
Specimen 40.—An asexual coenobium with eight gonidia of 
about 35 to 40 » diameter is shown in Plate 4, fig. 28. 
Specimen 41.—An asexual] coenobium with eight symmetrically 
arranged gonidia of about 57 » diameter is shown in Plate 4, 
fig. 27. In the photograph the coenobium measures 230 » wide 
and 220 » long. In 1921 the specimen had shrunken further to 
206 » wide and 191 » long. Most of the shrinkage occurs in the 
membranes. Each gonidium is contained in the outer side of 
a gelatinous capsule that is very thin on the outer side and s0 
thick in other directions as to crowd the neighbor capsules so
