 By R. von Lendenfeld, Ph.D. 



Plates XL., XLL, XLIL, XLIII. 



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

 Hydromeduste from different Australasiatic localities, which I 

 obtained after my papers on the Hydromedusse were read, will 

 he described, and a few erroneous statements corrected. 



They are the following : — 



I. SUBOKDO HYDROPOLYPIN^E. 



1. FAMILY. HYDRIDE. 

 1. GENUS. HYDRA. Liune. 



2. HYDRA FUSCA. Limie\ 



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

 medusse, because the specimens referred to it are identical with 

 H. oligactis. Pallas. 



5. FAMILY. BLASTOPOLYPID^. 



4a (70). GENUS. MONOSKLERA. 



10b (231). M. PUS1LLA. Nov. Spec. 



An interesting representative of a new Genus from Port 

 Phillip. 



6. GENUS. LAFGEA. 

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



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

 very similar to Lafcea pai-asitica Ciamician.
