Australian Rotifera. By James Murray. 165 



described till later parts. As far as possible, these have been 

 explained by notes in parentheses. 



Historical Sketch. — This notice of works on Australian Eotifera 

 makes no claim to be complete. I have not yet had time to seek 

 carefully through the Australian Societies' publications for recent 

 years. It is a note of such works as I have seen or heard of, and 

 is chiefly concerned with the Bdelloids. These have received scant 

 attention in Australia, as usual everywhere and always. 



Schmarda, 1859 (5)* found Pterodina patina in New South 

 Wales. Thirty years later, Thorpe (11) in his first list of Queens- 

 land Rotifers, makes the first mention of a Bdelloid (Actinurus). 

 Whitelegge's list, 1889 (16), contains 110 species (6 Bdelloids). 

 Thorpe's second list of Queensland Eotifers, .1889 (1£), includes 



4 Bdelloids, and in another paper in the same year (13) he notes 



5 Ehizota, a Brachionus and Pcdalion. Also in 1889 (2) Hudson 

 and Gosse describe 3 new Ehizota, and mention a fourth. Anderson 

 and Shephard, 1892 (1), in their list of Victorian Eotifers, note 

 4 Bdelloids. Strickland, 1894 (10). also notes 4 Bdelloids. 



Papers by Thorpe, 1891 (U); Shephard, 1896 (6'), 1897(7), 

 1899 (8); Shephard and Strickland, 1899 (9); Eousselet, 1899 (3) 

 and 1900 (4), deal with Ehizota only. Thorpe, 1893 (15) notes an 

 Asplanchna and Asplanchnopus. 



The Bdelloids in all these works number only 9 species — 

 Philodina roseola, citrina, mcgalotrocha, aculeata ; Rotifer vulgaris, 

 macroceros, citrinus, tardus, neptunius. 



The Rotifer citrinus in the above list is not recorded by anybody, 

 but Strickland's notes on a Rotifer sp. ? (10), which he thinks may 

 be R. macrurus, seem to me to indicate R. citrinus. 



List of Species. 



Ploima. 



In the water supply of Sydney, and in ponds in the public 

 parks, a few species other than Bdelloids were noted. As most of 

 them are already in Whitelegge's list for the same district, they 

 are omitted from this list. I only note a few which are not in 

 Whitelegge's paper. 



Triarthra brachiata Eouss. 



Notops minor Eouss. 



Binocharis inornata Hilzendorf. 



Metopidia acuminata Ehr. 



M. rhomboides Gosse. 



Biaschiza gibba (Ehr.). 



Brachionus ureeolaris Ehr. 



Pedalion sp.
