TSE VICTORIAN NATURALIST. 53 



in a sheltered spot, an aneroid reading was taken in the bed of 

 the stream beside the bridge, and the depth of the valley found 

 to be about 150 ft. The road up the other side of the valley was 

 then followed, and in a cutting iron-stained sands passing up into 

 fawn-coloured sands and quartzites were again observed over- 

 lying the irregular surface of the Older Volcanic rock. When 

 the top of the hill was reached we found ourselves once more on 

 the level of the plateau. A detour was then made to the east- 

 ward, and at a locality marked on the geological map a search 

 was made for graptolites. A fair number of specimens were 

 found, though the variety of forms proved to be very small. 

 They were pronounced to be of Upper Silurian age, but their 

 identity has not yet been established. A start was then made for 

 home, and after a five-mile tramp from here we reached the 

 Essendon railway station, having safely escaped collision with the 

 numerous bicyclists, and with shoulders sore from the weight of 

 our spoils. In conclusion, it may be mentioned that the Essendon 

 station is 146 feet above sea level, that at St. Albans 218 feet ; 

 and the aneroid gave the plateau at Green Gully and at the 

 Keilor Church as 254 feet, and the bed of the creek at the bridge 

 100 feet above the sea. — T. S. Hall. 



NOTES ON THE BIRD FAUNA OF THE BOX HILL 

 DISTRICT. 



By Robert Hall. 

 {Read before Field Naturalists' Club of Victoria, 12th April, 1897.) 

 In continuation of my notes on the bird fauna of the Box Hill 

 district read before the Club some months ago, and published in 

 the last volume of the Victorian Naturalist (vol. xii., pp. 127- 

 143), I wish to bring under your notice the birds to which the 

 group-name of " Warblers " can be applied. These, in my dis- 

 trict, number no less than ten of the twenty-two Australian 

 species, though one of them here included is structurally not a 

 true warbler ; but many field observers will doubtless agree with 

 me in considering the Blue Wren, Jfahtrus cyaneus, Ellis, almost 

 the finest warbler we have, from a vocal point of view. 



The Emu Wren, Stipiturus malachurus, Lath., has lately been 

 excluded from the list of " Warblers," but is included here, being 

 of similar habit, &c, to the last-mentioned species. 



A third species, the Reed Warbler, Calamoherpe Australis, 

 Gould, seems also to have come under an act of separation. It 

 is a fine warbler, and, although during day and night always to 

 be found in the reed-beds, is generally referred to as one of the 

 Sylviinae, or inhabitants of the woods. All along the eastern 

 coast of Australia this species may be found, while a second
