The fish fiiuiia (tf tilt' whole ic^ioii triivciscd is poor in comiyarisoii with tliat of the 

 streams of tilt- Oliio N'allt'V. I obtained in ail but (m species. al)out LM> pt-r eeiit ol' 

 wliicli were new to science. 'I'liey belonj; to 11 families and In genera. In the Win 

 nipej;' system. /. '., in the whole re;;ion drained by the tiibnfaries of liake Winnijie;:. 

 only.! of the 10 families characterizing the Nearctic n-jiion were oi)tained. and the 

 Pacitic Slope «'oiiiains only two. 



The followin,, notable additions to the knowledjie of th«' Noith American fann;i 

 weie made b\ these explorations: 



1. A species of l'initi>.stfiis { l'.coli(mhit(inis I'. Jonhiiii u\' t\ir Missouri) discovered 

 on the I'acilic Slope. 



L'. \i)t urns fid n(.s found at the base of the Hoekies at (.'raij;", Mont. 



;!. I'our new species of Xotrojiis added to the ea/it ( 'anailian fauna. 



4. Two new species of Atjosia added to the I'acilic fauna. 



■"). A new species of whitetish (6'(>/vy/»h/(.s' coitltcri) disct»vered in the Ivocky Moiin 

 tain streams of a restricted rej;ion in Ihitish C%)lumbia. 



(). The fandlyof I'mopsithv found to have a reiiresentative on the l*aeiti«; Slope m 

 the new genus Coliimhio. 



7. Several species of E'heostoma found in Canada, among them two new species. 



8. One new i'ottus [('. omjclntH) added to the fauna of the Saskatchewan.

 .since secured from the Columbia. 



U. It was discovered that the tins of the fishes of the I'acilic Sloi)e vary from the 

 tins of fishes of the Atlantic Slope in definite directions. 



12. The extent of variation between the species of any given family of fishes on 

 the l*aciiic coast was found to be greater than that between the species of the same 

 family on the, Atlantic Slope. 



1.'). RicliiirdsDiiiKs was ]»roved to be a subgenus of IjeiiciscKn. Its species were 

 found to vary directly witii the locality. Kach locality examined has a variety which 

 in the aggregate differs from the variety of every other locality.
