416 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



99. Fundulus lineatus (Garruau). Northeastern Wyoming (as Zygonectes lineatus 

 type, Garman, 1881). 



100. Fundulus macdonaldi (Meek). Jones Creek, Dixon, Mo. ; Osage River, Marsh- - 



field, Mo. (as Zygonectcs macdonaldi types, Meek, 1891). 



101. Fundulus floripinnis (Cope). South Platte River near Denver (Haplochilus 



florijnnnis type, Cope, 1874) ; Denver, Colo, (as Haplochilus floripinnis, Cope 

 & Yarrow, 1876); South Platte River at Denver (as Zy g on ectes floripinnis, 

 Jordan, 1891). 



102. Fundulus sciadicus Cope. " Nebraska or Platte River" (type, Cope, 1865); 



Floyd River at Lemars; Platte and Elkhorn rivers at Fremont (Meek, 1891). 

 Numerous specimens of this species were obtained. It was found at the 

 following places: Ponds at Niobrara, Creighton, and Long Pine; Creighton 

 Creek, Niobrara; Long Pine Creek, Long Pme; Dismal and Middle Loup 

 rivers, Dunning; Loup River, Ravenna; Prairie Creek, Scotland, and Rock 

 Creek, Mitchell. Specimens have recently been sent to the Commission from 

 Dover, McCook County, S. Dak., by Mr. Fred. S. Butler. The center of 

 abundance for this region seems to be in northeastern Nebraska and south- 

 eastern South Dakota, the largest number of specimens having been 

 obtained about Scotland, Niobrara, and Long Pine. It was also common at 

 Dunning, and probably occurs in all suitable waters of Nebraska and South 

 Dakota. It seems to prefer the small grassy ponds and lakes, but it also 

 finds a congenial home in the sluggish grassy creeks so common in this region. 

 In the small, isolated pools along the creeks among the Chara, Potamogeton, 

 and Myriophyllum, in which they abound, these little "top minnows" could 

 usually be found in large numbers swimming about at the surface. Usually 

 the vegetation was so abundant that it was difficult to secure any of these 

 fish with the seine. A dip net or a very short seine generally gave the best 

 results. The largest specimens secured are 2J inches long, and may be 

 described as follows : Head 3§ ; depth 4 ; eye 4 ; snout 3^ ; interorbital width 

 li times eye. D. 10; A. 12; scales 35-10. Body short and stout ; head flat, 

 snout pointed, the lower jaw slightly projecting; caudal peduncle com- 

 pressed and deep, its least depth nearly ecpial to snout and eye. Teeth in 

 each jaw in about 3 series, those of the outer enlarged and somewhat curved 

 inward. Fins all small; the pectorals about as long as depth of caudal 

 peduncle; -ventrals much shorter; origin of dorsal behind that of anal and 

 nearer tip of caudal than to occiput. Color in life, rosy olivaceous, pro- 

 fusely covered with line brownish punctulations; middle line of back, 

 darker ; in spirits, uniform olivaceous or brownish, paler below ; dark line 

 on back evident. 



103. Eucalia inconstans (Kirtland). Brook Stickleback. Poplar River, Poplar, 



Mont. (Eigenmann, 1894). The brook stickleback was found only in Crow 

 Creek, near Chamberlain, and in the ponds and creek at Long Pine. Mr. 

 Fred S. Butler, of Dover, S. Dak., has kindly sent us specimens from that 

 place. Over 50 specimens were secured, all but 4 of them from Long Pine. 

 In the small grassy ponds at the head of Long Pine Creek it is very abun- 

 dant. The largest specimens are 2 inches in total length. Head 3^; depth 

 3i; eye 3f ; snout 3£. D. iv or v-i, 10 or 11; A. i, 9 or 10. In 31 examples 

 counted the dorsal was 1V-1, 10 in 12 ; I v-l, 9 in 2 ; I v-i, 11 in 1 ; v-i, 10 in 10 ; 

 V-I, 9 in 4, and v-i, 11 in 2. In the same examples the anal was i, 9 in 16 

 and i, 10 in the remaining 15. Body smooth throughout. Ventrals very 

 short, wide apart, innominate bone covered by the skin about 1J times 

 length of ventrals. Color, dark brown above, pale below. 



104. Percopsis guttatus Agassiz. Trout Perch. Kansas (as P. hammondii type. Gill, 



1864); Kansas River near Fort Riley (as P. hammondi, Cope, 1865); Big 

 Sioux River at Sioux City; Boyer River at Arion, Iowa (Meek, 1892); 

 Floyd River at Lemars, and East Okoboji Lake (Meek, 1894).
