very short, blunt, shorter than eye. Dusky ; a dusky lateral band through 

 eye, ending in a faint black spot at base of caudal; a black speck above each 

 pore of lateral line; chin black. Length 1| inches. Western New York, 

 (Cayuga Lake; Meek) to Northern Illinois ; rather scarce. (, without; 

 )evff, chin.)

405. NOTROPIS CAYUGA, Meek. 



Head 4; depth 4|; eye 3. Scales 36, 14 before dorsal. Teeth 4-4. 

 Allied to N. heterodon, from which it may be best known by the absence 

 of black on the chin. Lateral line wanting on some scales ; mouth very 

 small, anterior, the maxillary not reaching the eye; jaws subequal; eye 

 large, equal to snout. Scales above dark-edged, the outlines very sharply 

 denned ; chin not black ; a black stripe through snout and eye, a dusky 

 lateral shade and a small caudal spot. Length 2i inches. Cayuga Lake 

 and northern New York, westward to Assiniboina, South Dakota, 

 Nebraska, Kansas, and Arkansas, (Arkansas River at Wichita, Kansas). 

 Not rare, but hitherto usually confounded with N. heterodon.

Represented southwestward by 



405a. NOTROPIS CATUGA ATROCAUDALIS, Evermann. 



Head 4| ; depth 4 ; eye 3. D. 8 ; A. 7; scales 7-36-4, 13 before dorsal. 

 Snout somewhat longer ; lateral line complete. Body moderately elongate; 

 head short and bluntly conic ; snout slightly shorter than eye ; caudal 

 peduncle short and deep; origin of dorsal slightly behind ventrals; anal 

 small. Olivaceous, dotted above, not crosshatched ; a black lateral 

 band half width of eye, ending in a black caudal spot, this band extend- 

 ing through eye and snout. Rio Neches, Palestine, Texas. Also in Rio 

 Comal at New Braunfels, Texas, (ater, black; cauda, tail.)

*The following is the description giveu of Notropis lieterolepis : D. 9 ; A. 9. Scales 5-35-4, 15 

 scales before the dorsal. Teeth 4-4. Dorsal inserted equidistant between base of upper caudal 

 rays and anterior margin of eye, behind last ray of dorsal ; scales loosely imbricated, almost em- 

 bedded in front of dorsal ; scales along the median line with a deep notch near middle of posterior 

 margin ; the line nearly straight; a few black specks along base of anal, a dark line from anal 

 to caudal ; a dark band from tip of snout along sides to caudal ; a conspicuous black curved Hue 

 at base of each tcale of lateral line ; all the scales above lateral band dotted with black; a nar- 

 row vertebral line from occiput to dorsal, a broad dusky band on back between dorsal and caudal, 

 between this and lateral band a lighter band ; scales of back with dark markings ; series of min- 

 ute black dots along each ray of dorsal, anal, and anterior portion of pectoral ; dorsal and caudal 

 quite dark. Eigenmann. 



Dr. Eigenmann has omitted to describe the mouth of this species. According to Dr. G. A. 

 Boulenger, who has kindly examined the type in the British Museum, the mouth is quite small, 

 moderately oblique, the lower jaw not included ; premaxillary extending to below anterior nos- 

 tril ; chin not black. Eye very large, longer than the short, convex snout. Only one specimen 

 (35 mm. long) known. Apparently not different from Notropis cayuga. (erepds, various ; ACJU'S, 

 scale.)
