Head 4; depth 5.5; eye 3.25; snout 3.75; D. 8; scales 36, 10 in series 

 from dorsal to ventral fin; longest dorsal ray 1.34 in head ; pectoral 1.5; 

 ventral 2, reaching anal. Teeth 4-4, slightly hooked, grinding surface 

 narrow. 



Body rather terete and slender; snout bluntish; mouth small and 

 slightly oblique; lower jaw the shorter, slightly included; posterior end 

 of maxillary scarcely reaching vertical from the front of orbit. Eighteen 

 scales between nape and dorsal fin, the scales in this region being smaller 

 and more crowded than ou sides and posterior dorsal region, much resem- 

 bling Pimephales notatus in this respect ; lateral line incomplete, not extend- 

 ing beyond the fourth scale on each side. Origin of the first ray of dorsal 

 fin midway between the base of the caudal fin and the tip of the snout; 

 the longest (anterior) dorsal rays nearly three times the length of the 

 posterior ones, the tips of the former extending considerably beyond the 

 tips of the latter when the fin is deflexed. Color olivaceous, darker above, 

 very pale below ; a dark band about f diameter of eye around snout and 

 m side to base of caudal fin; on the snout this band is confined to the 

 ipperjaw; between this band and the darker color on the dorsal region 



a lighter band of about the same width; a dark vertebral line present, 

 Iso a similar one from base of anal to caudal fin. In some specimens the 

 iteral line is absent on the first scales and appears at intervals on about 

 scales, but it is occasionally absent altogether. It is less developed 



this species than in any other of the genus. 



Close to JV. cayuya, from which it differs in the reduced size of the scales 



jfore the dorsal, the more slender body, the sharper snout, the slightly 

 irger and more oblique mouth, and the more incomplete lateral line. It 



also a larger fish than JV. cayuga. 



Known only from Gull Lake, near Muskoka Lake, Ontario, where 24 

 ipecirnens were obtained by Dr. Meek in September, 1899. They vary in 

 length from 1.31 to 2.91 inches. (Named for Muskoka Lake.)

lightly concave from latter point to base of caudal ; ventral outline evenly 



mnded to end of anal base; deepest part of body just anterior to inser-
