134 BULLETIN OF THE UNITED STATES FISH COMMISSION. 
The color of the western form is darker, and the position of the dorsal fin is farther 
back than in the eastern forms examined. The eastern form apparently reaches a 
larger size. 
Specimens of this species were taken by Jordan & Gilbert in the White Eiver and 
its branches about Eureka Springs, Arkansas, in 1884, aud in their list it was included 
with Notropis hoops under the name of JSFotropis scabriceps. The true scabriceps is not 
found in Arkansas and JSf. hoops is a distinct species. 
17. Notropis rubrifrons (Cope). 
Warm Fork, common ; English Greek, scarce. 
18. Hybopsis kentuckiensis (Eafinesqiie). 
Spring Eiver, Myatt and English Creeks, common. 
19. Hybopsis amblops (Kafinesque). 
One specimen from English Creek. 
20. Semotilus atromaculatus (Mitcbill). 
Myatt Creek, Spring Branch, scarce. 
21. Salmo irideus Gibbons. Rainbow Trout. 
One specimen taken in Spring Eiver, below the dam, escaped, no doubt, from the 
hatchery. 
22. Fundulus catenatus (Storer). 
Myatt Creek, abundant. 
23. Zygonectes notatus (Eafinesque). 
Spring Eiver, Myatt and English Creeks, very common. 
24. Lucius vermiculatus (Le Sueur). 
Myatt, one specimen. Very abundant in a bayon of Spring Eiver about three 
miles below Mammoth Spring. 
25. Lucius reticulatus (Le Sueur). 
English Creek, one specimen. Branchiostegal rays 14 and 15. 
Bayou near Spring Eiver, one specimen, 24 inches in length, Length of the head 7^ 
inches. From tip of snout to the eye 4 inches. Dorsal rays 14, anal rays 14, only 
long rays counted. Brauchiostegals 15. Scales in the lateral lineAlO. Cheeks and 
opercles scaly. Sides reticulated, the reticulations forming rather indistinct and 
irregular lateral stripes. This large specimen difiered in color from several smaller 
specimens taken at same time aud in same place. The large specimen was taken in 
a trammel net which was stretched across the bayou near its mouth. The sportsmen 
owning the net informed us that it was not uncommon to take pickerel of this size 
from the bayou. 
The siiecimen from English Creek was compared with the Eastern and Southern 
specimens of L. reticulatus, from which it presented no apiireciably specific or varietal 
differences. I have also examined a specimen of this species from Spring Vallejo, 
Shannon County, Mo., taken by Prof. E. E. Call in 1888. In a paper published by 
Professor Call on “ A Collection of Fishes from the Ozark Eegion,” in the Proceedings 
of the Davenport Academy of Sciences in 1887, the following notes are made under 
the species Usox vermiculatus : “ Sinking Creek, Spring Valley Creek, and Jack’s 
Fork, Shannon County. This species, which is locally called mountain trout, and 
occasionally pike, is abundant in all the larger streams in the mountains of Mis- 
souri.” I have also been told by Professor Call that some of the specimens taken 
were from 18 inches to 2 feet in length.
