Plate X.

[Read before the Wellington Philosophical Society, 3rd August, 1892.]

The animalcule known as Floscularia coronetta is rare in England. It is worth recording that a Floscularia almost identical with the English form was found by me in water at the back of the Hutt Parsonage. The drawing (Plate X.) accurately represents the New Zealand form. The only differences between this and the English rotiferon is that the arms in my specimens are longer than those in Hudson's and Gosse's drawings, and the knob at the end of the arms is not circular, as in their drawings, but oval. The animal is rare here, as well as in England.
