ventrals. Its origin is about equidistant from tip of snout and base of caudal. The specimen has 

 only a faint lateral band. 



14. Notropis cooglei n. sp. 



Spot-tailed minnow 



The authors are aware of the complexity of the group of fishes assigned to the genus Notropis 

 and of the inadequate definitions of many of the species. Under the circumstances, they naturally 

 hesitate to add another name. It has been impossible, however, after examining available literature 

 and making comparisons in the National Museum with supposedly related forms, to identify the 

 specimens at hand with any known species. As no other course appears to be open, we propose 

 for them a new name and describe the specimens as follows: 



Diagnosis. — Body deep, compressed, depth 3.55 to 4.05 in standard length; snout pointed, 

 as long as eye; mouth terminal, oblique; pharyngeal teeth 4-4 or 1, 4-4, 1, hooked; dorsal rays 9 



Fig. 3.— Notropis cooglei n. sp. From a paratype 



or 10; origin of fin a little behind ventrals; anal rays 10 or 11; scale formula 6 or 7-37 to 42-4 or 5, 

 from 15 to 18 in advance of dorsal; exposed part of scales on sides notably deeper than long; lateral 

 line strongly decurved; an evident dark caudal spot present. 



Description of type. — Body deep, compressed; the back elevated, the depth 3.65 in length; head 

 4.15; snout short, 3.33 in head; eye 3.75; mouth rather large, oblique; maxillary not quite reaching 

 front of eye, 3.75 in head; interorbital convex, 2.5; scales notably deeper than long on sides, 38 in 

 lateral line, 7 between lateral line and origin of dorsal, 4 between lateral line and origin of anal; 

 lateral line complete, decurved, far below axis of body; origin of dorsal a little behind insertion 

 of ventrals or midway between tip of snout and base of caudal, margin of fin nearly straight, the 

 anterior rays not reaching the tips of the posterior ones when deflexed; caudal fin deeply forked, 

 both lobes pointed and of equal length; origin of anal at vertical from end of dorsal base and a 

 little nearer base of caudal than margin of opercle, outer margin of fin slightly concave; ventral 

 fins reaching slightly beyond origin of anal; pectorals pointed, 1.15 in head. 



Color. — Bluish silvery above, becoming pale silvery underneath; sides posteriorly with a 

 diffuse plumbeous band; an evident black caudal spot present; dorsal fin pale, with numerous, 

 dusky punctulations, giving the fin a generally smoky appearance, particularly distally; caudal 

 fin pale, with somewhat fewer dusky punctulations than the dorsal; the other fins yellowish in life 

 almost white in spirits. 



Variability. — The specimens at hand show a rather high degree of uniformity of the various 

 proportional measurements taken, as well as in fin and scale counts. In 17 specimens, varying in
