30 Excursion to Lake Covangamite and District. [voT"^'"xxxv 



the lake, where fresh water from the springs makes marshy 

 ground and enters the lake by soakage and shallow surface 

 film almost without current, holes made by hooves of cattle, 

 &c., contained water covered with Azolla filicidoides and Lemna 

 minor. Other plants of the vicinity were Isoetes fluviatilis, 

 Nasturtium officinale, Cotula {coronopifolia ?), Cyperus, sp. ?, 

 the introduced flat-weed, Hypochceris radicata, and Triglochin 

 striata. Among or attached to some of these were sterile 

 filaments of Spirogyra, Zygnema, Mougeotia, CEdogonium, Volvox 

 globator, Closteriiim Ehrenbergii, Closterium cymthea, several 

 species of Navicula, and Arcella vulgaris, &c. On the eastern 

 side of Corangamite the shelly beaches overlying basalt extend 

 inland, interspersed with Salicornia australis, &c., which lead on 

 to the dry-land grasses. Among the rocks, and within reach 

 of salt spray, Senecio lautus and thistles grew sparingly with 

 Chenopodimn album, and the flat-weed was plentiful beyond 

 high-water mark. 



The results of the excursion are on the whole very satisfactory, 

 and it is hoped that further investigations will be carried out 

 before long at a different season of the year. Intending visitors 

 to the Red Rock district can obtain at the Tourist Bureau a large 

 scale map of the locality, which will be more serviceable than the 

 small sketch map herewith. — J. Shephard. 



TWO SNAKES NEW TO VICTORIA, 



With a List of the Victorian Species. 



By J. A. Kershaw, F.E.S., Curator of the National Museum, 



Melbourne. 



{Read before the Field Naturalists' Club of Victoria, 14th Jan., 1918.) 



Two species of snakes not previously recorded from Victoria 

 have been recently added to the National Museum collection, 

 both of which were captured in the Mallee, in the north- 

 western portion of the State. 



These I have been able to identify as Rhynchelaps australis, 

 Krefft, and Denisonia nigrostriatu, Krefft. The former was 

 described from specimens obtained in the neighbourhood of 

 Port Curtis, Queensland, and on the Clarence River, northern 

 New South Wales, and the latter has been recorded from Rock- 

 hampton, Queensland. 



Rhynchelaps australis, Krefft. 



This is a small species measuring 11 inches long, of a bright 

 red colour, with a series of narrow cross-bands of whitish, 

 black-edged scales, extending half round the body. These 

 bands, of which there are 55 altogether, each occupy one row
