DENDKOSOMA KADIANS, EHRENBEEG.

Fig. 43. — Urnula epistylidis, showing the formation of the 
gemmnla. Copied from Claparede and Lachmann (5) (PI. 10, fig. 3). 
Fig. 44. — Free-swimming gemmnla of Urnula. Copied from Clapai-ede 
and Lachmann (5) (PI. 10, fig. 3). 
Fig. 45. — A portion of the body of an Urnula very mnch enlarged to 
show the spiral marking of the tentacle (C). 
Fig. 46. — A specimen of Trichophrya epistylidis (s^j. .‘') found in 
the Bridgewater canal attached to the stalk of an Epistylis. (From a 
stained preparation.) No microuucleus could be seen. Size 129 5 /i 
X 111 
Fig. 47. — A very young Deiidrosoma with one arm and one micro- 
nucleus, also attached to an Epistylis stalk. Tlie size of this sj)ecimen 
is 6P3 n in gi’eatest length, including the arm. From a stained pre- 
paration. 
Fig. 48. — Another rather older Deiidrosoma with three micronuclei. 
Size 60 IX, -f the arm 60 /i = 12(f fi. From a stained preparation. 
Fig. 49. — Lernaeophrya (sj). ?) from the Bridgewater canal. Drawn 
from a living specimen January, 1909. 
Figs. 50-52. — Three figures drawn to the same scale ( x 1000) to 
show the varying structure of the meganucleus of Dendrosoma. 
Fig. 50. — Section through a part of an arm (Birmingham 
material) in the region where the meganucleus terminates. 
The terminal extremity was in the direction of the upper 
side of the figure, but was not included in the actual 
section. Two micronuclei are seen beyond the mega- 
nucleus. The size of the largest granules was only 0'85 /x. 
Fig. 51. — Section through an arm showing two ineganuclear 
bands. The chromatin granules are smaller than in fig. 
50, but the meganucleus contains peculiar, large, iiregular 
bodies which give the chromatin reaction. 
Fig. 52. — Section through a meganucleus (Bridgewater canal 
material). The largest chromatin granules seen in this 
section are 2'5 p in diameter.
