Cumshewa Inlet, belongs to that section of the genus Olco- 
stephanus for which M. Pavlow has since proposed the sub- 
genus Virgatites.' 
Hopuites HarpAQqueEnsis. (Sp. nov.) 
Plate VII, figs. 2,2 a & 2 6. 
Shell small, strongly costate and widely umbilicated, 
the umbilicus, as measured from suture to suture, occupy- 
ing about one-third of the entire diameter. Volutions 
about three, though the nucleus is not preserved in the 
only specimen collected, increasing rather rapidly in size 
and slightly embracing: the outer one moderately convex, 
a little broader than high, the outline of a transverse sec- 
tion being subpentagonal if made through one of the ribs, 
or not far from circular if in the centre of one of the grooves 
between them: aperture nearly circular but shallowly emar- 
ginate by the encroachment of the preceding volution. 
Surface marked by large and prominent, simple and 
nearly straight, transverse ribs, which are separated by 
rather broad concave grooves. The ribs, which are equal 
in length, are most elevated on the outer or peripheral por- 
tion of the last volution, and in the median line of the peri- 
phery there is a single angular notch on each rib which 
scarcely interrupts the continuity of the rib. 
Sutural line not clearly defined, but apparently. not very 
complicated nor much branched. ‘The first and second 
lateral saddles appear to be much broader than high, and 
doubly incised rather than ramose at the summits. The 
first lateral lobe seems to be trifurcate above and unusually 
small, though apparently much larger than any of the 
others except the siphonal lobe. 
Maximum diameter of the only specimen collected, 
twenty nine millimetres: greatest breadth of the same, 
twelve mm. 
The specific name suggested for this little Ammonite is a 
modification of the word Hai-da-kwe-a, which Dr. G, M.
