Abstract of the Proceedings, November 24th, 1909. — Mr. Froggatt 

 exhibited a collection of Thynnidae (Flower- Wasps) comprising 135 named 

 specimens, among them being 14 types and many co-types of the species 

 described by Mr. Rowland Turner in his monograph of the family published 

 in the Society's Proceedings for 1907. These specimens at that time were 

 in Mr. Turner's charge at the British Museum, and were not available for 

 exhibition when the papers were read. — Mr. T. H. Johnston exhibited 

 an extensive series of Entozoa from the Barracouta fish [Tityrsites atun 

 Euphr.) — 1) Tetrarhijnehiis sp. (Sydney; Clarence River; Tasmania; Western 

 Australia), an elongated form 5 — 15 cms. long, with swollen anterior end 

 containing the scolex, somewhat like that of Tetrarhynchus reptans Wag.; 

 infesting the muscles. 2) Tetrarkym^ms sp. (Sydney), a short thick parasite 

 iibout 2 cms. long, also from the muscles; the spherical rostella, and the 

 general body-shape, seem to resemble those of T. rugosus. 3) Tetrarhynchus 

 sp. (Sydney; Clarence River), a very small, actively motile cestode, with long 

 rostella and powerful bothria, this immature parasite occurring commonly in 

 and on the intestinal coats. 4) Tetrarhynchus sp. (Clarence River ; Sydney), 

 a tiny pedunculated cystic form, found on the mesentery and peritoneum. 

 5) SjìarganuìH sp. (Clarence River), a larval Bothrioeephalid, about 1 — 5 cms. 

 long, found in the outer coat of the intestine. 6) IvJithyotaenia sp. (Clarence 

 River), a young form with a well developed apical sucker; this occurs in the 

 intestine. 7) Echiuorhynchus sp. (Clarence River), from the intestinal walls. 

 8) Immature nematodes, regarded by Dr. G. Sweet, of Melbourne, as 

 Ascaris marina Linn. ; these round worms are extremely common in the 

 Barracouta, occurring spirally coiled in great masses along the whole of the 

 mesentery (Sydney; Clarence River; Tasmania; West Australia). With the 

 exception of Ascaris uiarinaÇ?) recorded from Victoria, none of these parasites 

 have been noted before from Australia. The specimens were mainly collected 

 by Dr. Cleland and Messrs. F. H. Taylor, and T. H. Johnston. — 

 3) Contribution to our knowledge of Australian Hirudinea. Part iv. With 

 a Note on a Parasitic Endoproctous Polyzoon. By E. J. God dard, B.A., 

 B.Sc. , Linnean Macleay Fellow of the Society in Zoology. — The paper 

 comprises a detailed account of a leech found in the Brisbane River, which 

 is regarded as indistinguishable from the Jamaican Pontohddla macrothela 

 Schmarda; and descriptions of a species oï Pontohdella from the Hawkesbury 

 Estuary, and one of Geobdeila from British New Guinea. Certain incomplete 

 but abundant structures adherent to examples of the second of these are 

 pronounced to be the stalks of an F^ndoproctous Polyzoon, possibly allied to 

 Loxosoma. Similar structures were erroneously supposed to be the sper- 

 matophores of a leech, by Macdonald.
