[Photomicrographs of Copelandosphaera dissipatrix sp. nov. from specimens mounted in glyc- 
erine and Venetian turpentine, taken by W. R. Shaw and E, Cortes at the Bureau of 
Science, Manila.] 
PLATE 1 
Fic. 1. Sexual coenobium, mounted in glycerine, containing about one hun- 
dred twenty-seven oogonidia and seven antheridia. Four of the 
antheridia appear in the photograph, two presenting a surface 
view and two an edge view. xX 100. 
2. A portion of the same specimen showing the two antheridia that 
present a surface view and four of the oogonidia. Most of the 
somatic cells are out of focus in the photograph, though some 
near the ends of the figure, along the line between the dark and 
light protoplasts, are in focus. X about 200. 
3. A portion of the same specimen on a larger scale. The scale at 
the right is a part of a stage micrometer scale with smallest 
divisions of 10 u» that was photographed on the same plate and 
with the same adjustment of apparatus that was used for the 
specimen. X about 405. 
PLATE 2 
Fic. 4. A nearly mature sexual coenobium in glycerine. The oogonidia 
on the lower side are more nearly in focus than those on the 
upper side. Number of oogonidia counted, 130. x 50. 
5. A nearly mature sexual coenobium in glycerine. Number of oogo- 
nidia counted, 112. x 50. ; 
6. An asexual coenobium, the type specimen, in Venetian turpentine. 
This is shown on a larger scale in Plate 3, fig. 13. x 50. 
7, An asexual coenobium in glycerine. It has four daughters in 
about the 1,024-celled stage. x 50. 
8. An asexual coenobium in glycerine. It has fifteen embryonic 
daughters in about the 64-celled stage. The photograph shows 
the open phialopores of those embryos that face them toward 
the observer. x 100. 
9. An asexual coenobium in Venetian turpentine. It has ten daughter 
coenobia. Of these eight contain gonidia and in two no repro- 
ductive cells are yet differentiated. These are probably sexual 
daughters. x 100. 
10. An asexual coenobium in glycerine. It has eight embryonic 
daughters that are in the 256- or 512-celled stage. X 50. 
PLATE 3 
Fig.11. An asexual coenobium in glycerine. It contains ten embryonic 
daughters. X 100. 
12. Part of a sexual coenobium in Venetian turpentine. It shows 
some immature oospores and some flask-shaped unicellular algae 
that are embedded in the membranes of the somatic cells. X 400.
