Cottus gulosus (in part) Jordan & Evermann, Fishes N. & Mid. Amer., pt. 11, p. 1944, 1898. 
A widely distributed and somewhat variable species. Found throughout the basin. Specimens 
from Stanislaus River, Parrot Ferry, American River near Placerville, Feather River at Oroville, War- 
ner Creek, Battle Creek at the government hatchery, McCloud River at Baird, and Sacramento River at 
Sims, have teeth on the palatines which are wanting in specimens from other places, and in some of the 
specimens from the places just mentioned. The patch of prickles behind pectoral fins is universally 
present. The opercular spines are variously developed; one is always present at lower end of sub- 
opercle; and one is always present at upper corner of preopercle. The two lower preopercular spines 
may or may not be developed; usually they are mere rounded projections and covered by the skin. 
When present the second preopercular spine projects downward; this is especially noticeable in the 
specimens from Warner Creek. The dorsal fins are continuous or very slightly joined. The size of the 
eye is somewhat variable.

vertical at front of pupil, its length 2.5 in head; teeth in jaws and on vomer, none on palatines; those 
on sides of jaws weak, extending on upper jaw only about half way to corner of mouth; anterior nos- 
trils in short tubes; the posterior nostrils without tubes, smaller than the mucous pores; mucous pores 
arranged as in klamathensis, two pairs above front of eyes, a single median pore posteriorly between 
orbits and a circle of pores behind each eye; other pores posteriorly on head; interorbital narrow, 
about one-half of orbit, the bony septum about one-third; top of head behind eye very slightly con- 
cave; opercular spines small, sharp; lower spines of preopercle wanting; lower spine of subopercle 
sharp, smaller than upper spine of preopercle, which is curved upward; tip of opercle flat, rounded; 
spinous dorsal low, its spines about 6. Height of soft rays, which are equal to snout and half of eye, 
about the same as in klamathensis, the two fins broadly joined for from one-third to two-thirds the height
