out by Professor McCoy. Fig. 1 1 is apparently G. Thureaiii and 

 fig. 12 is this new species. Etheridge, moreover, amongst 

 other associated forms, quotes PhyUograptus typiis, a genus -which 

 in Victoria does not range as high as the Loganograptus zone 

 and Didymo. Pantoni (McCoy, M.S.). This latter species Professor 

 McCoy* says is identical with Hall's Tetragraptiis fruticosi/s, an 

 identification which is frequently overlooked. Sir Frederick 

 McCoy also records Z. Logani from Newham,f but an examination 

 of the specimens in the National Museum, on Avhich this record 

 was presumably founded, shows that they have the aspect of 

 G. Kjemlfi., and the non-occurrence of Loganograptus Logani at 

 Bb. 29 is also shown by the fact that PhyUograptus typns is also 

 quoted by the Professor from the same locality (Bb. 29). In fact 

 it appears that Bb. 29 is on an outcrop of the Tetragraptiis 

 friiticosus zone. Herrmanj also seems to have considered the 

 two forms as identical at one time, but to have subsequently 

 altered his opinion. Having regard to the cliflerent horizons of 

 the two forms, the importance of distinguishing them will be 

 manifest. 



Above the Loganograptus zone, my detailed observations do 

 not extend. To the westward of Castlemaine, fossils are very 

 scarce, a single specimen of PhyUograptiis was gathered by Dr. 

 Dendy, in my company, on the strike of about 200 yards west of 

 where I have noted the occurrence of the L.oganograptiis zone, 

 and a few specimens of T. caduceiis from the same and other 

 localities are almost the only identifiable fossils I have seen. The 

 difficulties attending their discovery here, have been noted above. 

 In his notes on the Maldon sheet, Ulrich states that the only 

 fossil found in the silurian rocks of that district was a single 

 specimen which he quotes as Hynienocaris verniicauda (Salter). 

 Possibly this is the ubiquitous Lingulocaris McCoyl (Eth., Jun., 

 = LLynienocaris Salteri, McCoy, M.S.). Mr. Norman Taylor also 

 mentions^ that he has found no graptolites in the country 

 immediately south of the Maldon strike. From Daylesford, how- 

 ever', twenty miles south on the same auriferous band, we find 

 graptolites in profusion, and a small collection in the possession 

 of Mr. John Hammerton, of Geelong, the only ones from there
