33 Cottus asper Richardson. Prickly Bullhead. 
Nine small specimens collected in Lake Washington, June 15. Head nearly or quite naked, hut 
entire body except belly uniformly covered with small prickles. 
34 . Cottus gulosus (Girard) 
A Cottus which we with some hesitation refer to this species is very abundant in fresh and 
brackish waters in Siuslaw River and in the lakes south of Florence, and easily caught on a trawl, or 
with hook and line. Mapleton, Oregon, Siuslaw River, 25 specimens ; Acme, Oregon, South Slough, 1 ; 
Whoahink Lake, 3; TsiltcoosLake, 20; Tahkenitch Lake, 9; Lake Washington, 1 ; Lake Sammamish, 2. 
35 . Cottus punctulatus (Gill). 
One specimen, 2,75 inches long, obtained from the stomach of a bull trout, Alturas Lake, July 16, 
1896. Five from Alturas Lake, July 30, 1896. 
36 . Cottus princeps Gilbert. 
Cottus prince-pa Gilbert, Bull. U. S. F. C. 1897, 12, with figure. 
. Eighteen specimens from Pelican Bay, Upper Klamath Lake. Head 31 ; depth 5 ; D. viiorvm 
20 or 21; A. 16 to 18; eye 5; snout 4; interorbital width 5f. Ventrals i, 4; lateral line scarcely 
complete ; anterior portion of body covered with prickles ; posterior part smooth below. Head rather 
long, pointed ; maxillaries reaching to front of pupil. Color same as in C. leiopomus, which it closely 
resembles, but from which it differs in the more numerous dorsal and anal rays, the shorter snout, 
somewhat broader interorbital, and in having the body covered with prickles. 
37 . Cottus klamathensis Gilbert. 
Cottus klamathensis Gilbert, Bull. U. S. F. C. 1897, 10, with figure. 
Head 3J; depth 4J; eye 3|; snout 3£; D. vii, 19; A. 13 or 14; V. i, 4; interorbital width 5; 
maxillary reaching front of pupil. No teeth on palatines; a single straight preopercular spine, appar 
ently disappearing in older examples; nostril in distinct tubes; body short, stout; head moderately 
broad, wedge-shaped anteriorly ; caudal peduncle short, compressed, its greatest width 2 in eye, least 
depth 1 in eye; gill membranes joined to the isthmus, widely separated; body smooth. Color rather 
light; body with about 10 obscure irregular vertical blotches, but everywhere covered with minuet 
brown spots, a V-shaped bar at base of caudal; spinous dorsal with a dark blotch on its posterior 
portion; soft dorsal profusely covered with fine black specks; caudal faintly barred with dark and 
lighter. A single small example from the lower end of Upper Klamath Lake. 
Fig. 6. — Uranidea tenuis F.verniann & Meek, new species. 
38. Uranidea tenuis, new species. 
• TypeNo. 48229, U. S. N. M. ; cotypes No. 5705, L. S. Jr. Univ. Mus., and No. 434, U. S. F. C. Type 
locality: Lower end of Upper Klamath Lake, near Klamath Falls, Oregon, November 10, 1896. 
Collectors Meek and Alexander. 
Length of type, 3 inches, or 3f inches including caudal. Apparently allied to Uranidea marginata. 
Head 3f ; depth 7; eye 4^; snout 4; V. i, 3; D. vr-i, 17 ; A. 15. Vomer with teeth ; palatines tooth- 
less. Head long, contracted from eyes forward; snout rather long; body much compressed, very 
slender; greatest width of caudal peduncle 2^ in eye; least depth of same slightly^ greater than eye; 
preopercular spine well developed, broad, rather sharp, partly covered by skin, curved upward ; below 
this two other spines, the anterior one blunt, the other sharp, directed toward lower base of pectoral; 
post-temporal spine well developed. Body r smooth, wholly without prickles or scales; lateral line
