In this paper a series of new or otherwise interesting species of 

 Hydromediisse from different Australasiatic localities, which I 

 obtained after my papei's on the Hydromedusae were read, will 

 be described, and a few erroneous statements corrected. 



They are the following ; — 



I. SUBORDO HYDROPOLYPIN.E. 



1. FAMILY. HYDRIDE. 

 L GENUS. HYDRA. Liune. 

 2. HYDRA FUSCA. Linn6. 



This species must be struck from the list of Australian H3 dro- 

 medusae, because the specimens referred to it ai'e identical with 

 H. oligactis. Pallas. 



5. FAMILY. BLASTOPOLYPID^. 



4a (70). GENUS. MONOSKLERA. 



10b (231). M. PUSILLA. Nov. Spec. 

 An interesting representative of a new Genus from Port 

 Phillip. 



6. GENUS. LAFCEA. 

 18a (232). L. CYLINDRICA. Nov. Spec. 

 A new Species from the Bay of Islands, New Zealand, which is 

 very similar to Lafoea parasitica Ciamician.
