ing European Middle Cretaceous species, most of which are eminently 

 characteristic of the Gault : — 



Schloenbachia inflata, Sliy. 

 Hai)loceras Beudanti, Brngt. 

 " planulatum, Sby. 



Lj'toceras Timotheauum, Mayor. 



Thetis (major, var.) affinis. 

 Mytilus lanceolatus, Sljy. 

 Inoceramus concentricus, Par] 

 Actinoceramus sulcatus, Park. 



And probably 

 Camptonectes curvatus, Gein. & Gryphtea vesiculosa, Sby. 



As might be expected, under the circumstances, some of the fossils of 

 the LoAver Shales range downwards into the Upper Neocomian or latest 

 division of the Lower Cretaceous, while others extend upward into the 

 Upper Cretaceous. 



Those species which have the downward range indicated are, — 

 Ancyloceras Remondi, Gabb : Aucella Piochii, Gabb, which latter though 

 rare in the Lower Shales of Skidegate Inlet is abundant in the Upjjer 

 Neocomian of the mainland of British Columbia : Nemodon Fischer i, 

 d'Orbigny, a Eussian Neocomian fossil : and Syncyclonema Meehtni, Wh., 

 which is found also in the upper Neocomian of the valley of the lower 

 Fraser river, B.C. 



Those which range upwards into the Upper Cretaceous are Nautilus 

 Suciensis and Teredo Suciensis, Whiteaves, both of which occur also in 

 the Upjjer Cretaceous of the Sucia Islands, also Nucula {Acila) truncata- 

 Nucida solitaria and Terehratella ohesa of Gabb, which were originalh' 

 described from the Chico Group of California. 



Two species which have been described and figured by Stoliczku in 

 his Cretaceous Fauna of Southern India, viz.. Ammonites Sacya, Forbes, 

 which Neumayr says is a Lytoceras, and Trochactceon cylindraceus, 

 Stoliczka, are abundant in the Lower Shales of Cumshewa and Skide- 

 gate Inlets, the former at four localities, viz., Nos. 1, 3, 4 and 5, the 

 latter so far as known, at Maud Island only, or No. 9. 



Some of the fossils of the Lower Shales occur also in the "Shasta 

 Gi'oup " of California. These are Ammonites Batesi, Trask, which is a 

 Lytoceras: Ammonites Breweri, Gabb, which is a ^(t/^tocems; Ammonites 

 Stoliczkanus, Gabb, which is most likely a Hoplites : Ancyloceras Bemondi, 

 Gabb : Aucella Piochii, Gabb : and pi-obably also Pleuromya jyajryracea, 

 Gabb. 



In a paper "on the Lower Cretaceous Eocks of British Columbia," 

 which was j)ublished in the first volume of the Transactions of the 

 Eoyal Society of Canada, the writer endeavoured to show that the
