 This species has been described by Bale (1). The Gonophores 

 have not been found hitherto. A specimen which I obtained from 

 Timaru, New Zealand, bears Gonophores. (Fig. 9.) They ar e 

 pretty large, barrel-shaped and annulated. Transverse ridges run 

 round them like hoops. These are particularly well visible in the 

 distal part and less distinct towards the rounded base, which is 

 sessile on the stem.

I described (2) this species in a former paper and have now 

 obtained a series of small Medusa?, which lead up from the small 

 young Medusae which were produced by the Polypcolonies in my 

 Aquarium to adult Sarsise. I obtained all intermediate stages 

 with the surface net in early spring in Port Jackson. 



The adult Medusa?, filled with ripe generative elements, is about 

 four times the size of the larva at the time of liberation. The 

 shape is the same with the exception of the gastral tubular Gonad. 

 The Medusa is 2i mm. broad and 3 mm. high. The manubrium 

 slightly shorter in proportion than in the larva.
