Descriptions of Two New Species of Ammonites. 445 
Dawson quotes as the Indian name for the Queen Charlotte 
Islands, in his report on these islands, published in the 
Report of Progress of the Geological Survey of Canada for 
1878.79.' The shell itself appears to belong to the sub- 
group Dentati-regulares of the Dentati. of Pictet’s classifi- 
cation of the Ammonites in the ‘“‘ Paléontologie Suisse,” ? 
and to that section of the genus Hoplites which Zittel calls 
the group of Ammonites interruptus? In many of its char- 
acters it is very similar to Hoplites sinuosus, but it seems to 
have fewer and more distant ribs than that species and a 
different sutural line. Thus the type and only known 
specimen of H. Haidaquensis has twenty-two ribs on the 
outer volution, while that of H. sinuosis, which is almost 
exactly the same size, is said to have thirty-four. The 
sutural line of H. Haidaquensis seems to be more like that 
of H. crassicostatus, as figured by d’Orbigay,‘ in which the 
first and second lateral saddles are represented as broader 
than high, whereas the corresponding saddles of H. sinwosus 
are represented as higher than broad. 
The genus Hoplites also was proposed by Neumayr in 
1875, and is regarded as eminently characteristic of the 
Cretaceous epoch. H. Haidaguensis and H. Canadensis 
(nobis),° from the Clearwater shales and Peace River sand- 
stones of the district of Athabasca, are typical and charac- 
teristic Canadian species of this genus. H. McConnelli® 
(nobis), from the Clearwater shales of the Athabasca, ap- 
pears to be rather an aberrant member of that section of 
the genus which Zittel calls the “ group of Ammonites crypto- 
ceras.” It is also most probable that the fossil from Comox, 
Vancouver Island, which Meek doubtfully referred to his 
genus Placenticeras, under the name P. Vancouverense,' is 
also referable to Hoplites.
