17 Notropis jordani Eigenmaim & Eigeuinaun. 
Notfopis aUieohis E. & E., Aui. Nat., Feb., 1893 ; not N. albeoliis Jor(Ian=X. megalops. 
A .single .specimen, 73 min. long, obtained at Medicine Hat. This species is most closely 
related to N. maculatus aiid-W lieterodoii. In color it differs strikingiy from the latter, agree- 
ing in this respect witli maculatus, except that it lacks a caudal spot and is less profusely 
spotted. The lateral line is macli less complete than in helerolepis, and better developed than 
in macnlaius. Head, 4; depth, D. 94; A. 84; scales, 4-35-4; 15 scales before the dorsal; 
teeth, 4-4, 1, 2. Two of the teeth feebly hooked, the two others with narrow imperfect grind- 
ing surfaces. The teeth on the rightside are evidently abnormal, being arranged in three rows. 
Elongate compressed, more slender than heierolepis. Head much as in heierolepis, less convex 
above. Jaws equal; month oblique, the preni.axiliary on the level or lower margin of the 
pupil. Maxillary extending to anterior margin of orbit. Snout pointed, not decurved. 
Eye 3f in head, 1^ in interorbital. Fins all small ; origin of the dorsal over ventral, eijuidis- 
tant from base of middle caudal rays and nares, highest ray extending a little past end of the 
last ray when the fin is depressed, equal to head less snout; anal similar to dorsal, its highest 
ray equal to snout and eye; ventral e(iual to highest anal ray; pectorals longer, equal to head 
leas opercle. Scales closely imbricated, the exposed edges little higher than long. Lateral 
lino decurved, the tubes developed on less than 10 scales (some of those of the ndddle of the 
body are removed). General color silvery, no distinct markings. Ventral surface entirely 
white, a plumbeous lateral band overlaid with silver^'. A dark vmrtebral line from occiput 
to caudal. Sides with a few dark sjiecks, dorsal surface 'more densely specked, the margins 
of the scales darker. 
18 . Notropis heterolepi.s Eigennmnn & Eigenmaim. A specimen, 35 mm. long, taken at Qu’ApJielle. 
This species is evidently closely related to X4 heierodon, N. anogeiiiis, etc. It differs from them 
strikingly in having tubes developed in but one or two scales of the lateral line, while all 
the scales along the lateral line on one side and all but one or two on the other are deeply notched 
on their ])osterior margins. Head, 4; depth, 4J; D. 94; scales, 5-3.5-4 ; 15 scales in front of 
dorsal. Teeth feeble, 4-4 ; grinding surface well developed on three teeth. Head subcouical, 
little compressed, the snout rounded, little oljtuse; the lower jaw included. Mouth little 
oblique, the premaxillary below the level of the lower margin of inipil. Maxillary almost 
reaching eye. Eye large, 1 in snout, 3| in head, Ij in interorbital. Dorsal inserted equidis- 
tant from base of upper caudal rays and anterior margin of eye, behind the last ray of the 
ventrals. Tips of the lirst rays much jn-ojecting beyond tips of last when depressed, the 
longest ray about equal to head less snout. Anal similar to dorsal, the longest ray about If 
in head; ventrals reaching vent, equal to highest anal ray; pectorals equal to length of head 
less opercles. Scales loosely imbricated, almost imbedded in front of the dorsal. Scales along 
the median lino (lateral line) with o. deep notch near the middle of the posterior margins, 
the line nearly straight. A few black specks along base of anal ; a dark line along lower 
margin of tail from anal to caudal. A dark band from tip of snout .along the sides to the 
caudal; on the tail the band coincides in position with the scales of the lateral line. On the 
body it is placed a little higher. A conspicuous black curved line at the base of each scale of 
the lateral lino. All the scales above the lateral band dotted with black. A narrow vertebral 
line from occiput to dorsal, a broad dusky band on the back Ijetween the dorsal and caud.al, 
between which and the lateral band is a lighter band. Scales of the Ijack with dark margins. 
Series of minute black dots .along each ray of the dorsal, anal, and outer portion of pectoral; 
the dorsal and caudal ([uite dusky. 
19 . Notropi.s (Miniiilus) reticulatus Eigenmaim & Eigenmaun.' Brandon, Qu’Appelle. Thissxiecies 
is closely related to N. speciruHcuhts, fretensis, nUidits, and topela, and may prove identical 
with one or the other. It approaches nearest X. fretensis and topeka. From the former it 
differs chiefly in the larger scales in front of the dorsal, and from the latter in the naked breast. 
Head, 4; depth, 4-44; D. 9| or 104 (i or ii, 84) ; A. 94 (ii, 74) ; scales, 4 or 5-34-3 or 4 ; 12-14 
scales in front of the dorsal ; teeth, 4-4, hooked, with evident grinding surface. Head pointed, 
broad above and slightly convex. Snout decurved, pointed, the lower jaw included. IMouth 
oblique, the jiremaxillary on a level with the lower margin of the pupil or somewhat lower. 
*A larger series of spccimeus collected by Mr. A. J. Wooliiiaii in the headwaters of the lied Kiver make it probable 
that this sxiecies is N. deliciosus.
