428 Canadian Record of Science. 
representatives of the genus Goniograptus appear to be very 
nearly co-specific, and so identical are they, especially in 
their early or young stage, that it is not thought that a 
new specific designation is required. Should later investi- 
gations and the finding of additional material, both in 
Australia and Canada yield new facts, separating these 
widely separated forms (geographically speaking), other 
than those noted above—then I would suggest the varietal 
or specific designation Goniograptus Selwyni to include such 
forms as are included in the above description of the 
forms, merely adding that I have much pleasure in coupling 
Dr. Selwyn’s name with this interesting species, from the 
fact that to him “must be awarded the merit of finding 
the first graptotite (1856) which determined the age of 
the gold-reef-bearing slates of Victoria.” (See preface of 
Decade II, Pal. Victoria, 1875, p. 5). 
Locality and Formation: Fifteen hundred and sixty paces 
East of Lower Levis—Quebec ferry, in the black shales of 
the ‘‘Tetragraptus zone” met these in the I.C.R cutting, 
Levis, Quebec. 
Levis Formation (Cambro-Silurian or Ordovician) Col- 
lectors: Messrs. J. C. Weston and L. M. Lambe, 1886 and 
1887. 
Note—The affinities of this species with the forms 
described by Prof. Hall as Graptolithus Richardsoni, and 
G. ramulus are apparent, but the compound nature of the 
branching celluliferous stipes readily differentiate them. 
The figures (figs. 4 and 4a) of Decade I, Pal. Victoria— 
appear to answer weil to Hall’s G. ramulus which would 
evidently fall under some new generic designation whilst 
Prof. Hall’s specific name would include both forms. The 
remarkable identity of species occurring at localities so 
widely remote, geographically speaking, is pecularly note- 
worthy, Dr. Selwyn having collected many species precisely 
identical with Canadian forms.
