pleurse, by the presence of asmall point on each side at 
the back of the pygidium, etc. This species he calls O. 
Torrelli. 
With these two species of Olenellus, Dr. Moberg found a 
small Lingula?, two Hyolithes and a small Obolella?, and 
he supposes their geological age to be intermediate between 
that of O. (H.) Kjerulfi and O. (M.) Michwitzi. 
He has found in loose blocks of Cambrian sandstone a 
brachiopod of which the arched valve is said to resemble 
the shell of Ancylus. It is marked within by a set of radi- 
ating ridges like the supposed operculum of Hyolithellus 
micans and Dr. Moberg revives Dr. Hall’s genus Discinella, 
referring his species to it. As it has 14 radiating furrows 
in place of the 9 or 10 that are found on the form from 
Troy, N.Y., described by Hall, he considers it specifically 
distinct, calling it D. Aolsti. 
He very significantly remarks that in the material in 
which his Discenella was found, one ‘‘ very seldom finds any 
fossil which is plainly the living chamber of a pteropod of 
the type which Billings described under the name of Hyoli- 
thellus; and on the other hand one does not find the 
Discina-like fossil in the material where the reed-shaped or 
Hyolithus-like fossil is plentiful.” 
Dr. Moberg describes two species of Kutorgina; one 
doubtfully as such, having a very peculiar interior. This 
probably is of some other genus. Other genera described 
are Acrothele, Obolella?, Scenella??, Dentalium?, Hy- 
olithes, Volborthella ?.

MEMPHREMAGOG A CoLD WATER LAKE. 
By A. T. Drummonp. 
Lake Memphremagog is the Loch Lomond of Canada, but, 
being less easy of access from the great cities, does not 
attract the tourist as does the Scottish lake. It is, how- 
ever, not less beautiful. From the summit of Owl’s Head 
there isa view that for beauty and breadth is probably
