contracted specimen from Slipper Island the breadth was greater 
than the height. In some specimens the column was provided with 
indistinct Hongitudinal furrows corresponding to the insertions |of 
the mesenteries.

pharynx region (fig. 28) and the reproduction region (tig. 29). Fig. 28 spec. from Slipper 
Isl. Fig. 29 from North Cajie. Inner side upwards. 
In the lower half of the column I have observed cinclides in 
sections. The column is not provided with verrucae, the margin is 
rather distinet but there is no fossa. Though the mesenteries are

is provided with tentacles. The actinopharynx is long and provided
