FAUNA AND FLORA OF NORFOLK : ROTIFERA. 
The usually abundant Triarthra longiseta was almost absent, 
only three specimens being found on the west of Barton. 
The fascinating little Gasteropus minor did just put in an 
appearance at North Barton. Three specimens only. 
The giant Copeus elirenbergii occurred both in Sutton and 
Barton Broads, and I was delighted to find Furcularia cimolius 
(Gosse’s Ratlulas cimolius). 
I have often longed to see this speices, and now that I have 
seen it I am positive that it is a Furcularia, and not a Rattulus. 
Pretty little Furcularia longiseta was rare, but occurred 
in most places, except Barton and Hickling. 
Proales petromyzon occurred associated with Volvox 
£ lobator . 
Proales daphnicola also occurred, and through the kindness 
of Mr. Robert Gurney, I am able to give the names of the 
species of Entomostraca with which it was associated. 
I found it on three different hosts, Daphnia pulex, Sida 
chrystallina, and Eurycercus lamellatus. 
Amongst the Diglena, two specimens of grandis turned up in 
east of Barton. Forcipata and catellina also occurred, and 
my own species, Diglena rostrata, once only far north of 
Sutton. 
We pass on to the loricated free swimmers. The Rattulidce 
were very abundant. 
Eight species of Rattulus occurred, carinata, lophoessa, scipio, 
elongata, ratlus, bicornis, stylata, and bicristata. 
The genus Diurella has been recently revised by Jennings, 
of the U.S. Fishery Commission, assisted by Mr. Rousselet, 
and my friend, Mr. Dixon Nuttall. 
I was able, by sending some samples to the latter, to deter- 
mine tig) is, porcellus, tenuior, wcberi, and intermedia. 
I was delighted to come across three Scandium eudacty- 
lotum in the Fish Pond, and four Stephanops unisetatus in the 
Heater, both of which I had never taken myself before. 
Passing cn to the genus Diaschiza, a genus in which I feel 
very much at home after some years spent on its special 
study, 1 was delighted to find thirteen species represented 
in the Bioads, most of them occurring only in the fish pond,
