South Australia, and has also been recorded from New Zealand. 

 This distribution would seem to indicate that it occurs throughout 

 Australasia, and completes its cosmopolitan occurrence. 



Plumatella sp. — Other undescribed species have been known 

 for some time from New South Wales. 



Alcyonella sp. — Whitelegge has recorded a species whose stato- 

 blasts resemble those of Plumatella fruticosa in shape, and are 

 much narrower than those of A, fungosa. 



We have now represented in Australia six genera (includino- 

 Alcyonella), comprising six named species, and several unnamed 

 forms; and of these, three are definitely known as endemic species 

 — Plumatella Aplinii, Lophopus Lendenfeldi, and Fredericella 

 australiensis. 



Dendy has noted the occurrence of a species of Fredericella at 

 Christchurch, New Zealand, which he identified as F. sultana, 

 remarking on the occurrence of the same species in Australia. 

 He noted, however, that his specimen differed from that figured 

 by Allman for i^. sulta7ia "in being more slender and in the 

 suppression (complete or partial 1) of the ridge-like keel "'; also 

 that the epistome (whether due to contraction or not) was 

 bluntly rounded at the apex. I am inclined to regard this form 

 of epistome as being the natural condition of such in the extended 

 condition, inasmuch as the same is found in the species described 

 in this paper; and the New Zealand form agrees with this species 

 in the characters given by Dendy as differentiated from F. 

 sultana. Dendy has unfortunately not had the opportunity 

 of examining the statoblasts, and has not made any remarks 

 about dissepiments, both of which structures would be of much 

 assistance in determining the New Zealand species. The number 

 of tentacles is said to be "about twenty-two," and this character, 

 evidently noted in the entire individual, is the only one which 

 would prevent one, under our present knowledge of the species, 

 from suggesting that the New Zealand species may be none other 

 than F. australiensis.
