Several species of Myriapoda were collected by Mr. W. J. M'Caw, 

 among them being Scutigera maculata, Henicops maculatus, 

 Cormocephalus esulcatus, C. westwoodii, and Necrophloephagus 

 antipodum. 



Of land planarians Mr. Kershaw reports that six species were 

 collected. One of these, a small specimen found under a log on 

 the side of a hill, was unknown to him, but, on being forwarded 

 to Mr. T. Steel, F.L.S., of Sydney, who is devoting his attention 

 to this group, it was identified as Geoplana venti-opunctata, Dendy. 

 Tins prettry little species has also been recorded from Ferntree 

 Gully, where it was taken plentifully by Dr. Dendy on the Club's 

 excursion to that place in March, 1891. Several specimens of 

 Geoplana siigdeni, Dendy, were found crawling along the open 

 tracks, and one was taken on a tree trunk about 18 inches from 

 the ground. The following is a full list of the species taken : — 

 Geoplana ventropunctata, Dendy, G. sugdeni, G. mediolineata, 

 G. alba, G. spenceri, and G. frosti. 



Regarding the geology of the excursion Mr. A. E. Kitson, 

 F.G.S., furnishes the following notes : — 



The locality about Warburton possesses interesting geological 

 features. The rocks represented are Silurian sediments, com- 

 prising marine claystones, mudstones and sandstones ; Lower 

 Devonian grano-diorite, Upper Mesozoic or Lower Cainozoic 

 dacite and volcanic ash ; a series of clays, sandy clays and 

 clayey gold-bearing sands of probably Lower Cainozoic age and 

 of fluvio-lacustrine origin ; remnants of the Yarra River terraces 

 of pebbly gravels of Upper Cainozoic age ; and Recent alluvium 

 and hill wash. 



The Silurian strata can be seen in railway cuttings between 

 Yarra Junction and Warburton, and up the Yarra, a short walk 

 above this township. The beds are probably the same as those 

 of the Melbourne area, and reappear here owing to the folding 

 of the strata by earth movements. Those beds have been 

 grouped together by Professor Gregory, D.Sc, F.R.S., and called 

 the Melbourne Series or Melbournian — see "The Heathcotian — a 

 Pre-Ordovician Series — and its Distribution in Victoria," Proc. 

 Roy. Soc. Vict., Vol. xv. (N.S.), part ii., 1902 (1903). Where 

 noticed here they have a strike of about N., and dip to E. at 

 high angles. 



The grano-diorite occurs close behind the railway line at 

 Warburton, and extends back for many miles, forming the 

 mountainous country in Beenak and Tonimbuk. It has been
