which I have seen, contained the characteristic species of the 

 Tetragraptus friiticosiis zone. I cannot help feeling that the 

 same zone will be found at Maldon, though the highly meta- 

 morphic character of the rocks will make the discovery of fossils 

 dithcult. My last excursion before leaving Castlemaine was 

 made with a view of carefully searching the railway cuttings on 

 the Maldon side of Muckleford Creek. The first likely-looking 

 spot after leaving Maldon, however, was found only nine and 

 three-quarter miles from Castlemaine. Graptolites were found 

 on the first trial, but unfortunately were so decomposed that I 

 could not identify them. Numerous small crustaceans, possibly 

 Linguiocaris, also occurred. This was the only place where fossils 

 were obtained, though the country near Fentiman's Reef would, 

 I think, repay further search. 



TuE Graptolites of other Localities. 



The careful way in which the localities of specimens were 

 recorded on the maps, by the officers of the old survey, and the 

 references to those localities by Professor Sir Fredk. McCoy, in 

 his " Prodromus of the Palfeontology of Victoria," enable us to 

 make some interesting comparisons, and, at the same time, cause 

 us to wish that we had further elucidations of the hieroglyphics 

 on the maps. The fauna of the lowest Castlemaine zone, which 

 I have observed, agrees with the beds of Bendigo in -a very 

 marked manner. The Bendigo beds which I have examined 

 most closely are in Derwent Gully, a little below where the 

 Carshalton anticline crosses it, and at Ironbark, just west of the 

 Victoria Quarfz Mine, as well as less thoroughly at many other 

 spots. Mr. Wm. Nicholas, F.G.S., has given me a small number 

 of slabs of slate from near the Old Sarnia Reef at the south of 

 the field, and all three localities agree very closely in their fauna. 

 The agreement of an outcrop at Daylesford with this zone has 

 already been indicated. Besides Bendigo, Professor McCoy 

 recoi'ds T. fruticosus from Spring Plains (Bb. 45, Bb. 46, |S. 13 

 N.E.), the Upper Loddon on the strike of Chewton and Fryers 

 (Ba. 76, :J-S. 9 S.W.), and a couple of miles east of Gisborne (Ba. 

 71, |S. 6 S.W.) These localities then contain beds at or near 

 the same horizon, though doubtless it will be possiljle for sub- 

 divisions to be made later.
