Specimen 23.—Plate 1, fig. 6, shows a young coenobium with 
eight gonidia that are mostly about 27 », one being about 25 p 
in diameter. 
Specimen 24.—Plate 3, fig. 19, shows another young coenobium 
with seven gonidia, of which six are about 28 » and one about 
24 » in diameter. 
From the same pond that yielded specimens 8 and 9 (Plate 
4, fig. 24, and Plate 1, fig. 5) the following specimens were 
obtained: 
Specimen 25.—Plate 2, fig. 18, shows an asexual coenobium 
with eight gonidia in process of division. The specimen is very 
much flattened by the cover glass. The reproductive body at 
the right in the upper row and the first and third ones in the 
lower row are in the 4-celled stage. The others are 2-celled. 
They measure about 90 » wide. . 
Specimen 26—Plate 5, fig. 33, shows an anomalous case in 
which one of the eight reproductive bodies is smaller than the 
others. It measures 28 » wide; the others being 46 to 50 pz. 
From another pond, J, on October 13, a collection was made 
from which the following specimens were selected: 
Specimen 27.—Plate 3, fig. 17, gives a side view of a typical 
coenobium with nine gonidia of which the larger ones, about 46 
p» wide, form two characteristic quartets and a smaller one, 35 
p wide, occupies one of the places of a third quartet. 
Specimen 28.—Plate 3, fig. 15, shows an asexual coenobium 
with five asexual daughters and three gonidia. It is tilted ap- 
proximately 12° away from the observer. The daughters are 
the anterior quartet and the left, distant (out of focus) member. 
of the posterior quartet. The mother coenobium is only very 
slightly compressed by the cover glass, but the daughters are 
flattened parallel with the coenobium wall. Each of the daugh- 
ters contains eight gonidia, which are about 12 » in diameter. 
The gonidia of the mother are about 85 » in diameter. 
SMALLER FORM OF THE SPECIES 
From a small pool, B, in Pasay, about a quarter mile from 
the ponds, there was taken, in company with a species of Volvoz, 
what appears to be a small form of Merrillosphaera carteri with 
smaller gonidia. I shall assume that it is such and describe the 
specimens that are figured. 
Specimen 29.—A mature asexual coenobium with eight asexual 
daughters is shown considerably flattened in Plate 3, fig. 20. It 
presents a posterior view, and near the posterior pole there is
