University. No. 16. — Note on the occurrence of a Flagellate Infusorian 

 as an ìntra-cellular Parasite. By Professor Ha swell, M. A., D.Sc. The 

 parasites described were found infesting a large number of the unicellular 

 glands of the parenchyma of an undescribed rhabdocoele turbellarian from 

 a pond in one of the Sydney Parks ; they were present in sufficient numbers 

 to give a dull yellowish-green colour to the hosts ; by dint of crushing the 

 turbellarian the infusorians were set free from the interior of the cells and 

 their form and movements more easily studied ; within the cells the orga- 

 nisms were rarely at rest , incessantly creeping round and round the inte- 

 rior. — Mr. Hedley exhibited living specimens oî Panda atomatus, Gray, 

 drawing attention to the marked difference in sculpture between the em- 

 bryonic and adult shells, a feature of much importance from a systematic 

 standpoint. Also living specimens, lately procured from Scone by Dr. Cox, 

 of an Helicarion presumed to be leucospira, Pfeiffer, a long lost species which 

 has not been heard of since it was originally described in 1856 as coming 

 from »Australia«: a specimen of Cystopelta petterdi , collected by Mr. J. D. 

 Cox, at Mt. Wilson, the most northerly locality from which this mollusc 

 has yet been obtained : and examples of Helicarion thomsoni, Ancey, recei- 

 ved from Dr. Thomson of New Bedford, U.S.A., and collected at Géo- 

 graphe Bay , West Australia , by an American whaler , this novelty being 

 interesting as the first of the genus known from that colony. — Mr. Brazier 

 exhibited typical specimens, received from the author, of Diplomorpha dela- 

 touri, Hartman, and he contrasted them with a new member of this genus, 

 of which he showed specimens, from Siegond Island, Santo Espiritu, New 

 Hebrides: also examples of Fupa fallax from new Bedford, U.S.A., its 

 distinctness from the Australian P. pacifica, Pfr., with which some writers 

 have confounded it, being pointed out. — Mr. Froggatt exhibited speci- 

 mens of a rare sawfly, Philomastix glaber, Froggatt, and of its larvae, which 

 were found feeding on one of the wild brambles , Ruhus moluccanus ; they 

 were obtained by him recently at Mt. Vincent, Maitland, N.S.W., when on 

 a collecting trip for the Technological Museum, Sydney ; the species was 

 originally recorded from the Richmond River. Also a collection of Coleo- 

 ptera, chiefly lamellicorns, among them some rare species of Bolboceras, sent 

 to Mr. H. Maiden by Mr. Chisholm of Torren's Creek, one of the head 

 waters of the Flinders River, North Queensland. Also two male specimens 

 of a rare fossorial wasp , Thynnus brenchleyi , Smith, from the same locality, 

 together with a specimen of the other sex, Avhich may turn out to be the 

 hitherto unknown female of this species , previously recorded only from 

 Champion Bay, W.A., and Narrabri , N.S.W. — Mr. Rainbow showed a 

 spider, in all probability a new species of the endemic and widely distribu- 

 ted genus Stephanopis, from Bungendore. — Mr. Trebeck exhibited a 

 specimen of a flying fish, Dactylopterus orienfalis, from Port Jackson.
