NO. I FORMATIONS OF BEAVERFOOT-BRISCO-STANFORD RANGE 33 



Canyon (Allan). It may be that when the formations of the B. B. S. 

 Range are studied and areally mapped, that the Glenogle shales with 

 their included graptolite fauna will be found further to the south. 

 I looked for it in the Sinclair section on Sinclair Mountain but failed 

 to find its characteristic graptolite faunule. In a collection made by 

 L. D. Burling for the Geological Survey of Canada in a railway cut 

 just west of Glenogle station, Dr. Rudolf Ruedemann identified the 

 following species : 



Loganograptus logani tniit. tardus Ruedemann 



Didymograptus scrratulus Hall 



Didyniograptus sagitticaulis Gurley 



Didymograptus sp. nov. aff. D. forcipiformis Ruedemann 



Didymograptus sp. nov. aff. D. Uliformis Tullberg 



Didyniograptus spinosus Ruedemann 



Cryptograptus tricornis (Carruthers) 



Climacograpttis antiquus Lapworth 



Diplograptus cf. teretiusculus Hisinger 



Lasiograptus sp. nov. 



Glossograpttis horridus Ruedemann 



His comments on this faunule are as follows : 



There may be also two or more other species of Diplograptus in the material 

 but they are not well enough preserved to distinguished them readily. 



This fauna is a new association of forms indicating a horizon between the 

 Deep Kill and Normanskill shales. This is especially well shown by the presence 

 of such Normanskill types as Didymograptus sagitticaulis and D. scrratulus. 

 together with a later mutation of Loganograptus logani. Two of the species 

 here noted were so far known only from the Ashkill quarry faunule (at Mt. 

 Moreno near Hudson, New York; see Graptolites of New York, Mem. 11, p. 25) 

 namely: Didymograptus spinosus and Did. forcipiformis. (The Glenogle type 

 is somewhat coarser.) 



The faunas published by Lapworth from Kicking Horse Pass (1886) and 

 Dease River (1889), contain the most common forms of the present fauna, as 

 Cryptogr. tricornis, Climacogr. antiquus (equals C. caelatus of Lapworth's 

 list), Glossogr. horridus (equals G. ciliatus of Lapworth's list), Diplogr. 

 cuglyphus (variety of D. teretiusculus') and D. teretiusculus, Didymogr, sagit- 

 ticaulis (equals Sagittarius) ; and therefore belong to the same general horizon 

 as the one collected by Burling. 



The locality mentioned by Dr. Lapworth as Kicking Horse Pass 

 should be lower Kicking Horse Canyon, as the collection was made 

 near Glenogle station. 



Other localities of the Glenogle graptolite shale probably occur in 

 the folded and faulted shales, but as far as known no one has 

 attempted to make a systematic survey of the numerous exposures in 

 the canyon and the tributary gulches. The Sinclair shale graptolitic 

 faunule (of the Sinclair Canyon section) occurs 3.5 miles (5.6 km.)
