The male is totally unlike the female, resembling in its general 
characteristics the known males among the Melicertidae. Its form 
is sacculated, the narrowest part being the head, which is fringed 
with a wreath of cilia, and bears two minute red eyes, placed some- 
what close together (fig. 1 b). The body is, as usual, occupied by a 
large sperm-sac, in which the spermatozoa could be distinctly seen, 
as well as two or three large translucent vesicles. There is a large 
penis, but no foot. The spermatozoa have an oval head, with a 
flagellum about three times the length of the head attached to it 
along one side (fig. 1 c). 
In the body of another female Trochosphsera , which was dead, I 
came across a curious organism, which, I have little doubt, is a winter 
egg (fig. 1 d). It was nearly circular in shape, of a flattened appear- 
ance, with a dense central nucleus, which had undergone unequal 
binary division, the whole being covered with long spines. 
Floscularia torquilobata. PI. VI. fig. 2. 
Sp. ch. — Lobes five, broad, without knobs. Dorsal lobe arched 
towards the ventral surface, so that the setae point towards the foot. 
This large and handsome floscule was found, in May 1888, in 
a solitary bush pool on the shore of Gloucester Passage, coast of 
Queensland. It resembles in its general aspect and size F. longi- 
caudata. The dorsal lobe, however, is three times as long as the 
two ventral next in size, and is arched across the mouth of the 
coronal cup, so that the setae point downwards towards the foot, on 
the ventral aspect. In other respects its anatomy follows the usual 
type. Only a single specimen was seen. 
Brachionus furculatus. PI. VI. fig. 3. 
Sp. ch. — Occipital spines six, the outermost ones the longest. 
Two long lateral spines behind ; temporary only. Male loricated. 
This handsome Brachionus I found in a pool near Simon’s Bay, 
Cape of Good Hope, in December 1890. The general shape of the 
lorica resembles the egg of a skate. The antlers, the outermost of 
the six occipital spines, are the longest, being three times as long as 
the innermost, and are fantastically twisted in shape. The inter- 
mediate pair are mere saw-like projections. The animal carries two 
long lateral spines till an early period of adult life, and discards 
them afterwards. I have obtained many specimens which had no 
lateral spines behind, and two specimens with but a single 
spine on one side, and in another specimen there was a distinct 
constriction at the base of one of the lateral spines, apparently the 
commencement of self-amputation. The dorsal and ventral plates of 
the lorica are united at their edges for the upper three-fifths of their 
length. As this point, where the orifices for the lateral antennae are
