tion difficult, and specimens are poorly preserved. OncograiJtus 

 upsilon and varieties of Didi/mograj)tus caduceus occur as typical 

 forms, and Bidymoyraytus v-deflexus sp. nov. and TrigonoyraiJfus 

 are also found. Cardiogrojitus tnorsus, nov. sp., is absent, which 

 agrees with the evidence of other localities, and indicates that this 

 form is characteristic of a higher horizon. Oncocirapfus occurs a 

 little to the south on the same strike and in the creek bed half-a-mile 

 to the north, and even north of this. 



The next beds present some difficulty. Separated from the Onco- 

 ^rmptus beds by recent deposits, but only 200 yards from them, 

 typically Middle Castlemaine beds occiir. Vhyllograptiis typiis, J. 

 Hall, and small forms of Didymograptus caduceus, being found 

 in fair numbers in a narrow band of dec-oraposed white slate. These 

 beds also occur to the south, Avhere they are succeeded on the west 

 by Upper Castlemaine beds in the usual order. Along the raihvay 

 the next beds are also Upper Castlemaine. As the evidence of other 

 localities is very strongly against the Middle Castlemaine l>eing 

 within 600 feet of the Oncograptus beds, these Middle Castlemaine 

 beds seem difficult to fit in. Faulting is apparently responsible for' 

 their juxtaposition. More than this statement the evidence does not 

 warrant, but the common occurrence of slickensided faces and the 

 experience of miners shows that faulting is common in these rocks. 

 Between this outcrop and the 74:-mile post Upper Castlemaine l>eds 

 are found, and they are also well represented at the mile post. 

 This zone again repeats, and then no fossils are found until Chew- 

 ton is reached. Further search may reveal some, probably ISIiddle 

 Castlemaine, as such beds are exposed on the hills to the south and 

 to the north (at Burns' Reef). Just past the CheAvton Railway Sta- 

 tion (75 miles) 1). hifidus and P. tyjnis re-appear on the summit 

 of the ChcAvton ge-anticliuje on the strike of Dr. Hall's original 

 Wattle Gully beds, Wattle Gully itself crossing the railway line 

 immediately to the west. Higher beds — Middle Castlemaine — occur 

 along the same strike at Quartz Hill north of the line, but soutli- 

 wards all the beds are either of the same horizon (Lower Castle- 

 maine), or lower, as at Lost Gully (Daphne Reef) and Mount Eureka 

 (The Monk), where Upper Bendigo beds outcrop. The Wattle Gully 

 zone outcrops to the north in Cemetery Gully, and even further 

 north in Dirty Dick's Gully. This is interesting, as the 

 zone lias seemingly never been previously recorded north of 

 Forest Creek. At one spot a large variety of J), hifdus, with 

 branches about 40 mm. in length, is found. The only other Castle- 

 maine locality where it occurs is in Steele's Gully south of the
