line, 70 to 80 transverse rows along lateral line (16 to 18 above lateral 

 line, 69 to 72 transverse rows in F. oregonensis). D. 8; A. 8. In other 

 respects similar to P. oregonensis. Ptychocheilus harfordi is apparently not 

 distinct from P. grandis, being based on a specimen with very small 

 scales. P. grandis is confined to waters of California, F. oregonensis to 

 Washington, Idaho, and Oregon.

Head 4i; depth 4/;; eye 4; snont 3i; maxillary 3f. T). II, 9; A. II, 12 

 or 13; scales 11-58-8; teeth 2, 4-5, 2, somewhat hooked. Body rather 

 slender, slightly elevated and somewhat compressed; head small and 

 pointed, cheek not deep; snout pointed, somewhat longer than eye;- 

 mouth moderate, somewhat oblique, maxillary just reaching vertical at 

 front of orbit: jaws subequal, the lower sometimes slightly i>rojecting; 

 eye large, not as great as snout. Origin of dorsal liu behind base of ven- 

 trals and much nearer base of caudal than tip of snout, the longest ray 1^ 

 in head, greater than base of fin; origin of anal fin under last dorsal ray 

 but 2, its height equal to that of dorsal, its ba.se equal to its longest 

 ray; free edges of dorsal and anal nearly straight; pectoral 1^ to 1^ in 

 head, not reaching insertion of ventrals; ventrals short, li in pectoral, 

 reaching anus; caudal deeply forked; lateral line complete, decnrved. 

 Color in spirits, brownish or olivaceous above, middle of side with a broad 

 dark band involving the lateral line anteriorly and posteriorly, but lying 

 chiefiy above it mesially; middle of side from gill opening to beneath 

 dorsal fin with a broad rosy baud, following closely beneath the lateral 

 line; lower part of sides and under parts silvery, dusted over with fine 

 dark specks; a light yellowivsh band extending backward from upjier pos- 

 terior Itorder of eye nearly halfway to origin of dorsal fin; cheek with a 

 silvery or golden crescent; top of head dark; opercles duskj^ silvery; 

 snout dusky; fins plain, dorsal and caudal somewhat dusky. This species 

 is close to L. hulieatus, but has smaller anal and dorsal fins, a more slender 

 body, smaller and more slender head, and longer, more pointed snout. 

 The extent of variation in proportional measurements and in the niinil)er 

 of anal fin rays appears to be much less than in L. halteatus. It also 

 resembles L. cooperi, but has a much shorter lower jaw and a more pointed 

 snout. Known only from the .Siuslaw Eiver and Tsiltcoos Lake, western 

 Oregon, where it is common, (siuslaivi, of the Siuslaw River.)
