pcndulits, from Scoresby ; fasciated branch of Acacia suavcolcns, 

 bearing flowers, collected near Mount Eliza, on Langvsarriii 

 excursion. 



By Mr. J. Searle. — Ova. larva, and cercaria stages in the 

 life-history of Bilhazia — a fluke parasite affecting human 

 beings ; fossil jawlione (human) found near Swan Hill, Victoria.

EXCURSION TO LAXCWARRIX AXD FRAXKSTOX. 



Owi.xti to rough, boisterous weather, Monday, 4th June, the 

 King's Birthday holiday, was unfortunately quite unsuited for 

 a held excursion ; however, nine members journeyed to Lang- 

 warrin l)y train, and were met at the station by Mr. J. S. Mann, 

 a member resident in the district. Going south to a lane, we 

 followed it in a westerly direction to the Hastings road. The 

 uncleared land here carried Eucalyptus ainygdaliiia. Common 

 i\'pi>ermint, and E. cinerca multiflora, Alealy Stringybark, 

 with Casuariiia subci'osa. Black Sheoak, and Exocarpos cupressi- 

 Joniiis, th" Xative (Tierry or Cherry Ballart, with a varied 

 undergrowth, among which Hakca acicularis and H. nodosa 

 were in llower, and two Cassythas or Dodder-Laurels, C. 

 glabella and ('. puhcsceiis, were seen parasitic on the native 

 shrul)s. On the Hastings road we found on a Pep])ermint the 

 two Mistletoes, Loranllius celastroidcs and L. pcndulus. Aerial 

 roots were noticed on L. celastroidcs, but were absent from 

 L. pcndulus. Continuing southward along the Hastings road, 

 and the three-chain road that goes to Moorooduc station and 

 to Dromana, we found both mistletoes abundant, and aerial 

 roots on all samples which were dchnitely identified as L. 

 celastroidcs, \)\ii never on one definitely recogniza])le as the 

 other species. In consequence of the aerial roots and leafy 

 branches arising from them, L. celastroidcs spreads along the 

 tr(;e on wliicli it is growing, and presents an appearance of 

 starting from many points, whereas the other species is 

 localized at one point of attachment, which commonly ap])ears 

 in the case of a large plant of the mistletoe as the swollen end 

 of a branch, though closer examination reveals usually the 

 weak growth of the host plant beyond the point at which the 

 mistletoe is attached. There may be, of course, many in- 

 dependent clumps of either or both species on the one tree. 

 A spjcimen of L. celastroidcs is exhibited to-night cut into 

 sections to show the invasion of the tissues of the host |)lant 

 by the outgrowths from the aerial roots, and others which 

 clearly show that the aerial roots are produced quite early in
