in 1921, very convex. So it appears that the convexity shown 
in the figures is probably largely a result of shrinkage. Plate 
4, fig. 31, shows something of the thick capsular membranes 
around the daughters. 
MIXED REPRODUCTIVE BODIES 
Rarely (twice) coenobia were found that contained an anom- 
alous mixture of reproductive bodies. One such from Pond 
F was found associated with a nearly typical form of this species. 
It will be described next. 
Specimen 45.—Plate 8, fig. 28, shows a coenobium containing 
thirty-five reproductive bodies of three kinds. It measured in 
1916, 435 by 440 » with a thickness of ‘about 300 ». Now, in 
1921, its thickness is less and its dimensions are greater. The 
number of somatic cells was estimated to be about 4,360. Four 
of the reproductive bodies are asexual daughters. In one of 
these eight gonidia can be counted: In the others only six or 
seven can be seen, though there is some obscurity. Fourteen 
of the reproductive bodies are cells about 42 » wide, and seven- 
teen are smaller cells about 26 to 32 » wide. The former are 
vacuolate cells that I have supposed to be gonidia, and the latter 
are set down in my notes as oogonia. This assumption may be 
wrong. As before stated, this specimen is to be regarded as an 
anomaly. :

Carter’s description (’59, pp. 2 to 5 and 18 to 19, pl. 1, figs. 1, 
3, 4, 7, 8, and 10), given under the name of Volvoz globator, 
will now be recast in the terminology used in the present paper. 
His figures of this species are reproduced herewith in Plates 7 
and 8 on larger scales to make their dimensions directly com- 
parable with the micrographs of the Philippine material. His 
measurements were given in fractions of an inch. 
The form of the adult coenobium was described by Carter as 
spherical, or nearly so. The size, he stated, equals 770 ». A 
nearly mature asexual coenobium which he figured (Plate 7, 
fig. 42) measured, according to the scale given, about 744 p» 
broad by 765 » long. An oosporic coenobium which he figured 
(Plate 8, fig. 46) and stated to be the largest he had seen and 
about 608 » in diameter, measures 606 by 616 ». An antheridial 
coenobium shown in his fig. 8 (Plate 8, fig. 48) was stated to 
be about 270 » and the figure measures about 283 by 287 ». 
The diameter of the daughters before birth is shown to be at
