examples figured by Billings. The Harpides is also a diminu- 
tive species, judging from the fragment we have of it.” 
The specific conclusion to which I was led from the study of 
the above-mentioned fossils was that they represented the 
‘« Levis” formation of the Canadian geologists, although admit- 
ting the possibility that they might be found, on further inves- 
tigation, to mark a new or distinct division of that formation; 
and this conclusion I communicated to Dr. Selwyn. 
In a highly interesting and important paper, entitled ‘‘ Pre- 
liminary Report on some Graptolites from the Lower Palwozote 
Rocks on the South Side of the St. Lawrence from Cape Rossier 
to Tartigo River, from the North Shore of the Island of Or- 
leans, One Mile above Cape Rouge, and from the Cove Fields, 
Quebec,” published in the ‘‘'Transactions of the Royal Society 
of Canada for 1886,” Prof. Charles Lapworth, to whom the 
graptolitic species from the several localities named were sub- 
mitted, at the request of Dr. Selwyn, for identification and 
study, has reported upon the graptolites collected at St. 
John’s Market, Quebec, but makes no mention of the occur- 
rence at that locality of any of the other species already spoken 
of in this paper. It would appear from this that he was not 
aware of the occurrence there of the Trilobites, Brachiopods, 
etc., submitted to me by Dr. Selwyn; and this view is sustained 
by the fact that, on page 6 of his Report, he says: ‘‘There is 
nothing in the Cove Fields and St. John’s Market fauna that 
reminds us in the slightest degree of the fauna of Puint Levis. 
The fossils are the fossils of the Marsouin River fauna [7. e., ac- 
cording to Professor Lapworth, a fauna ‘Trentomian’ in 
character, under which designation he would also include the 
Norman’s Kill fauna] or second Ordovician [7. e., Lower Silu- 
rian| fauna, and have not a species in common with the first 
Ordovician fauna, the typical fauna of the rocks of Point Levis.” 
And further, on page 9: ‘*'The so-called Quebec rocks, of the 
town of Quebec, as typified by the fossils forwarded from the 
localities of the Cove Fields and St. John’s Market, are not of 
Quebec age at all. ‘They are probably the newest rocks repre- 
sented in the collection, and possibly shade upwards from the 
Marsouin Graptolitic shales of Orleans Island and Cape Rouge. 
They appear, however, to be of greater antiquity than the Utica 
slates of Lake St. John, answering to the basement zone of the 
British Bala, instead of to the middle zone, which seems to be 
the place of the St. John shales.” 
The only species cited by Prof. Lapworth from the St. John’s 
market locality, are Diplograptus rugosus? Emmons and JD. 
foliaceus? Murchison, and both of these, it will be observed, 
are only provisionally identified. If the horizon of these species
