By counting the number of hooks on a given length of a process before it has split, and afterwards, it is found that there were twice as many before as after on a given length and that the distances between them are half as great. It tlius appears that the hooks themselves do not split, but are arranged in a double row on each side, which, when splitting occurs, becomes divided into a single row on each side of each half of the pi-ocess. Fig. f Three immature statoblasts of L. capensis. Some immature statoblasts were sent by another collector to Dr. Rousselet, who, on hearing that I was describing the species, very kindly lent his preparation of them to me. Among the immature statoblasts are some which have the size and form of the central capsule. The terminal process is added last of all, during the completion of the development of the annulus (fig. 3). Annandale (' Records of the Indian Museum,' 1907, vol. i. part ii. pp. 145-149) describes a new variety of Lophopus.
