NOTES ON ROTIFERS AND SOME OF THE LIFE IN 
THE CHELMER SWAMP. 
(By W. R. Colledge). 
Ill former years, when the regular seasonal rains 
<'ccurred in February, the Chelnier ISwamp was occupied 
by a large area of water, and the adjacent low-lying 
fields were inundated, and it harboured many forms of 
aquatic life. Owing to the diminished rainfall of the last 
few years, these forms have been greatly reduced. The 
objects of my quest have been chiefly the Rotiferte, other 
forms being noticed as they were found within my net. 
Of the dainty forms of the Floscularidte, Coronetta or- 
nata and campanulata were found. The Melicertedm, 
ccuifera, ringens and annulatus, the second at certain 
times in great profusion. 
The colonial R<>tifers were well represented, the 
■vorld-wide form of t'onochilus Volvox being occasionally 
seen, and in the autumn the rare Megalotrocha Spinoza, 
discovered in China by Surgeon Gunson Thorpe. Fgg- 
shaped colonies of Lacinularia ovalis, and racemovata, 
Megalotrocha .semibulla, in very vigorous motion. Of 
tile Asplanchnidoe, beautiful specimens of the Amphora 
and Intermedia and Asplanchnopus Myrmcho, Sacculus 
Viridis, Syncheta, Stylata, and Tremula. Polyarthra 
Platyptera appears at all times of the year. In the spring 
Triarthra longiseta, and rarely Pedelion minim. Of the 
liytadinas, fine specimens of Notops brachiouus and Cla- 
vnlata, as well as sturdy sjiecimens of Typhilus lacustris. 
Of the Notommadm, Copeus copeus and cerberus, Diglena 
forcipata, Furcularia longiseta, and eqiiales. In the Rat- 
uilidic, bicornis, birostris, carinatus, and elongata; also 
Coelopns porcellns. In the Dinocharidiv, Tetractns, Eu- 
dactylotum. and longicaudatum, Salpina brevispina. In 
the Euchlanidui, Triquetra, and oropha are fre<tiient. The 
■■Cathypnadm are represented by Luna, Leontina, and IJn- 
gulata. The Pterodina by patina and reflexa. Members 
of the Braehionidai are numerous, angularis, Bakerii, Fal- 
catus, militaris. Palm, and Urceolus all being found. Good 
specimens of the bottom feeder Noteus quadricornis. 
Picosoma lenticulare have also been seen at rare intemuils.
