Neither dorsal nor ventral antennae could be detected, though the latter 
may possibly lie hidden amongst the spines. The oviferon is well 
developed, and is a cup-shaped organ into which the trunk of the 
rotifer is inserted, supported by side buttresses, and with a central 
process to which the eggs are attached. 'I'hefoot is extremely small, 
so that the ovifera lie together at the centre of the cluster. The eggs 
are longer and more slender than usual, with one end narrower than 
the other. No gelatinous tubes are present, but like M. semibullata , 
the animals secrete a mucous thread by which the cluster is occasion- 
ally suspended from the water plants.

This rotifer is not unlike B. Collinsi, possessing as it does, eight 
dorsal spines and a large ruby eye. It is, however, relatively broader, 
the distance between the spines of the posterior edge being greater. 
Also the spurs in the foot are absent. The lateral edges of the lorica 
are finely serrated, three of the teeth on each side of the shoulders 
being especially conspicuous. In all other respects its anatomy 
appears to follow that of D. Collinsi.

This new species is evidently a link between N. clavulatus and 
N. brachionus , since in its general contour it resembles the former 
rotifer, whilst its corona is similar to that of the latter. The corona 
bears three styligerous prominences between the two wreaths, each 
surmounted by a fan-like arrangement of styles. The trophi are of 
the malleate type, and the digestive and glandular systems are similar 
to those of N. clavulatus. The nervous system is represented by a 
large ganglion with a crimson eye seated on its ventral side and 
sending nerve-threads to the large dorsal antenna , and to the two 
conspicuous ventral antennae, situated on either side of the ventral 
surface below the middle line. The ovary is ribbon-shaped, and 
curved like a horse-shoe. The lateral canal on either side can be 
traced into a large contractile vesicle.
