21,2 Shaw: Copelandosphaera 215 
. nidia are dense and, except one, without spore walls. They 
are about 46 » in diameter. The number present is 130. One 
oospore wall had developed around a reproductive body some- 
what smaller than the others, about 41 » wide, that is of a 
more orange color than the others. . The wall is yellowish and 
wavy and not very thick. The protoplast has not contracted 
within the wall of this spore. 
Specimen 14.—Plate 2, fig. 5, shows a large sexual coenobium 
on the same small scale used for the preceding figure. It 
measures 870 by 973 y»; has its cells spaced about 10.7 #, and 
contains about 25,800 cells. There appear to be two empty 
antheridial sites on the nearer and one on the farther side. 
The oogonidia are about 46 » wide and are all dense and without 
spore walls. They number about 112. 
Specimen 15.—In the same Venetian turpentine preparation 
with the type specimen there is a sexual coenobium that is 
figured in Plate 4, fig. 15. It is very much shrunken. It con- 
tains eighty-one reproductive bodies of which all but ten have 
more- or less-developed, smooth spore walls from which in 
some cases the dense portion of the protoplast has contracted. 
They measure about 42 to 43 ». Some of them are shown on 
a larger scale in Plate 3, fig. 12. 
OBSERVATIONS ON LIVING SPECIMENS 
The paucity of recorded observations in my notes on living 
specimens of this species is due largely to the fact that in most 
collections the species was accompanied by several more-puzz- 
ling species of the same family. Descriptive data from these 
notes will be given to supplement those obtained from material 
in glycerine and Venetian turpentine. 
Specimen 16.—A living specimen in a collection from Pasig, 
August 4,1914. This was an asexual coenobium with ten daugh- 
ters and measured 900 by 950 ». It was observed to have no 
protoplasmic connections between the cells. The surface of 
the coenobium was smooth. The protoplasts of the mother 
measured about 6 » wide and were estimated to number 13,000. 
Measured daughters were 220 by 270 y», 260 by 300 », and 270 
by 300 ». The cells of the daughters were about 4 » in diameter, 
and the gonidia of the daughters about 18 » in diameter. 
Specimen 17.—On August 5, 1914, observations were made on 
living material that had been collected at Pasig the day before. 
“In this respect it differed from Campbellosphaera, which was repre- 
sented in the same collection.
