of the continent, Pan fosteus jordani, Coregonus nnlUamsoui^ 8(tlnio mylciss, Cafofttomns 
catosfonms, Salvelinus namaycush, Lota maculosa. (Rhinichthys dulcis is recorded from 
the Pacific Slope. 1 obtained none.) 
Forty-two species were found in the Winnipeg system. They are:

Eight of these species were found in the Saskatchewan and not in the Red River. 
They are:

I Couesius dissiinilis. 
Coregoims 'willianisoiii. 
I Sal 1110 inykiss. 
Etlieostonia iowie. 
Cottus ouyclius. 
Sixteen species were taken in the Red River of the Xorth and not in the Saskatch- 
ewan. Many of these will probably be found in the Saskatchewan when its lower 
waters are examined: 
Acipenser sturio. 
Ictiobus cyprinella. 
Moxostoma aureolum. 
Moxostoina anisurnm. 
Notropis lieterolt'iiis. 
Notropis reticnlatus.

Carpiodes velifer. 
Catostomus griseus. 
Catostomus commersoni.

I Notropis deliciosus.

taken in the Missouri are 
Notropis atberinoides. 
Rhiniebthys dulcis. 
Couesius dissimilis. 
Platygobio gracilis. 
Hiodou alosoides. 
Coregoims tvilliamsoni.

follows : 
Tbymallus signifer ontariensis.* 
Eucalia iucoustans. 
Stizostediou canadense griseum. 
Cottus bairdi puuctulatus.* 
Lota lota maculosa. 
Of these, but two s\)ecies {RhUiichthys dulcis &\\di Platygobio gracilis) are found 
both at Poplar and at Craig. Thirteen of the species taken in the Missouri are found 
in the Saskatchewan basin. 
The species of the Saskatchewan, with the exception of the new species, have all 
been taken in the Mississiiipi basin. The Saskatchewan basin, therefore, can not be 
sejiarated from the Mississippi basin by any positive characters. 
Not found in tlie Winnipeg system.
