Ot the Floscularia we have met with : — 



(i) Floscularia coronetta. In water from the Botanical 

 Gardens, and from a pond near Oakleigh. 



(ii) F. ornata. Botanical Gardens, Oakleigh, Brighton, &c. 



(iii) F. cornuta. Botanical Gardens. 



(iv) F. ccmvpanulata. Heidelberg, Brighton. 



(v) F. ambif/ua. Oakleigh. 



[and a species which I take to be new, and have named 



(vi) F.evansonii, (n. sp.) It is a small species, much shorter 

 and stouter in proportion to its size than most Floscules. 

 It has live linear, knobbed lobes, in which it resembles F. 

 coronetta, but it differs from it in having a broad cylindrical 

 corona with a distinct rim, on which the lobes are inserted 

 at some distance from each other. These lobes are short, 

 less in length than the diameter of the corona, and are very 

 motile, often coming right back till they lie in a plane at 

 right angles with the axis of the body, and they remind one 

 in their movements of the tentacles of the Polyzoa. The 

 corona is broadly barrel-shaped, with a distinct projecting 

 rim, and below it the body again expands somewhat befoi-e 

 it tapers to the foot. The breadth of the body is nearly as 

 great as that of the corona, and is one-third of the whole 

 length, while in other species it is usualh" one-sixth or less. 

 The tube is fluffy and irregular in shape. I found several 

 specimens in water obtained on July 6th, 1S91, from a 

 backwater of a stream near Oakleigh. They were tntli to 

 H^th in. in length, and were very bold, expanding freely.

[ (vii) In water obtained from the Botanical Gardens on 

 November 7th, I came across a single specimen of what is 

 apparently a new species of Stephanoceros. It had a three- 

 lobed corona, resembling Floscularia trilobata, but the sette 

 on these lobes were arranged as in Ste[)hanoceros, i.e., diago- 

 nally on the lobes in parallel bands. 'J'here were several ot 

 these bands round the summits of the lobes, and three or four 

 in the centre of the depressions between them. The cilia of
