412 Transactions. 



There is a general agreement in the fossils of Dr. Shakspear's collection 

 and the one before me, but owing to an unfortunate accident I have not 

 been able to define the contents of the beds exactly. 



None of the specimens were labelled when I received them, but those 

 from each locality were in separate parcels. There was, however, some 

 confusion in the localities. In one instance counterparts were attributed 

 to separate localities, and in two other instances I think that confusion 

 has taken place, though I am unable to distinguish the matrix. The 

 association, however, is not exactly what we know to occur in Victorian 

 strata, unless the two specimens be rejected. 



Arranged in descending order, the three localities are placed as follows : 

 (1) Tramway locality ; (2) Golden Ridge ; (3) Butcher's Gully. 



The following species have been identified : — 



(1.) From the Tramway Locality. 



Didymograptus extensus J. Hall. 



caduceus Salter. 



bifidus J. Hall. 



Phyllograptus angustifolius J. Hall (?). 

 Loganograptus logani J. Hall (?). 



In Victoria D. bifidus is not associated with the large variety or form 

 of D. caduceus which occurs in these beds. I therefore regard the single 

 specimen of D. bifidus, which has no other fossil on the same slab with it, 

 as wrongly included. There is, so far as I can see, no difference in the 

 matrix, nor, for the matter of that, is there much between that of the 

 three localities. The specimen doubtfully referred to Loganograptus logani 

 is very imperfect, but it is probably that species. Its associates, except 

 D. bifidus, do not forbid it. 



(2.) From Lowest Adit of Golden Ridge Mine. 



Didymograptus mundus T. 8. H. var. 



caduceus Salter. 



Tetragraptus serra Brong. 

 Dichograptus octobrachiatus J. Hall. 

 Goniograptus cf. crinitus T. S. H. 



- cf. laxus T. S. H. 

 Phyllograptus angustifolius J. Hall. 

 Diplograptus sp. 



The counterpart of the slab that contains I). octobrachiatus and the two 

 species of Goniograptus was included in the collection from the tramway- 

 line, so that their horizon is not quite certain. It is this clear case of 

 confused association that strengthens my idea that two other cases occur 

 as detailed below. D. mundus is closely allied to D. nitidus. 



(3.) From Butcher's Gully. 



Didymograptus extensus J. Hall (probably introduced). 

 caduceus Salter (probably introduced). 



- bifidus J. Hall. 

 Tetragraptus serra Brong. (?) 



- harti T. S. H. 



pendens Elles. 



Phyllograptus cf. typus J. Hall.
