Subgenus ALLOSMUS Jordan. 
Leucichthys manitoulinus Jordan & Evermann, new species. Manitoulin Tullibee. 
Argyrosomus tullibee, Evermann & Smith, Rept. U. S. Fish Comm. 1894, p. 320, pi. 28; in part. 
Type no. 64670, U. S. National Museum, a specimen 1 1 inches long, from Blind River, North Channel, Lake Huron; 
coll., Dr. Seth E. Meek. 
Habitat; North Channel of Lake Huron and probably lakes of Minnesota. 
Head 3.89 in length without caudal; depth 3.4; depth of caudal peduncle 2.5 in head; eye 4.5; 
snout 4; interorbital space 3.25; length of maxillary from tip of snout 2.75; dorsal 12; anal 13; 
branchiostegals 7 or 8; scales 8-71-8; between occiput and dorsal 24; gillrakers 16+29. 
Body somewhat over twice as deep as broad, comparatively elongate, more so than in Leucichthys 
tullibee, symmetrically elliptical; dorsal contour of the head straight; snout rounded, tapering; lower 
jaw slightly longer; maxillary extending to beneath anterior third of the eye, the supplementary bone 
three times as long as broad ; teeth on tongue very minute, none on jaws, vomer, or palatines ; width of 
opercle 4 in head, that of subopercle 7.5, measuring from anterior edge overlapped by opercle; gillrakers 
0.87 diameter of eye in length ; lateral line straight, ascending a little at the anterior end ; scales moderate 
in size, not deciduous, yet easily removed. Dorsal inserted midway between nares and base of caudal, 
its height moderate, the longest ray 1.33 in head; adipose fin smaller than in the true tullibee, being

Huron.) 
contained 4.25 to 6 in head, measured from insertion to free end; anal base one-half length of head and 
equal to its longest ray-, ventral insertion not much posterior to that of dorsal, its longest ray 1.5 in 
head, its scale contained 2.75 in its length; length of pectoral 1.33 in head. 
Color in spirits, dark on dorsal surface of head and body above lateral line, silvery below, all fins 
blackish but darker on the border; general hue suffused with smoky, as usual in fishes from waters 
colored by “muskeeg” or the wash of sphagnum and of peaty substances. 
This species is close to L. tullibee, from which it may be distinguished by the longer head, longer 
snout, more slender body, larger eye, and longer and larger maxillary. 
This description is based on three specimens, the type and two cotypes, at Stanford University, 
all taken by Doctor Meek at Blind River on the north side of the North Channel of Lake Huron 
Another specimen, smaller and more slender, is in the same collection. It is evidently one of the tulli- 
bee group, but it is not identical with the tullibee of the northwestern lakes, differing in the more 
elongate body and tail and in the smaller adipose fin. 
All these characters and every other one shown by the species are approximations toward characters 
shown by Leucichthys harcngus, the common lake herring of the same waters. We were told about the 
Manitoulin Islands that the tullibee was occasionally taken, but we saw no specimens other than 
these three.
