Head 4; depth 5.5; eve 3.25; snont 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; lovrer jaw the shorter, slightlj" 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 on sides and posterior dorsal region, much resem- 
bling rimepliales noiatus 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 snont; 
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 olivaceoics, darker above, 
very pale below ; a dark band about f diameter of eye around snout and 
on side to base of caudal fin; on the snout this band is confined to the 
upper jaw; between this band and the darker color on the dorsal region 
is a lighter band of about the same width; a dark vertebral line present, 
also a similar one from base of anal to caudal fin. In some specimens the 
lateral line isaljsent on the first scales and appears at intervals on about 
12 scales, but it is occasionally absent altogether. It is less develoj>ed 
in this species than in any other of the genus. 
Close to Ab cayurja, from which it differs in the reduced size of the scales 
before the dorsal, the more slender body, the sharper snout, the slightly 
larger and more oblique mouth, and the more incomplete lateral line. It 
is also a larger fish than Ab caijiiga. 
Known only from Gull Lake, near Aluskoka Lake, Ontario, where 24 
specimens were obtained by Dr. Aleek in September, 1899. They vary in 
length from 1.31 to 2.91 inches. (Xamed for 5Iuskoka Lake.)
