7. HIPPOGLOSSOIDES ELASSODON. 
[Plate V.] 
Hippogtossoides elassodon Jordan and Gilbert, Proc. U.S. Nat. Mus., 1880, 278 (Seattle, 
Tacoma, Washington Territory). Jordan & Gilbert, Proc. U. S. Nat. 
Mus., 1880, 454 (Puget Sound) and elsewhere. Bean, Proc. U.S. Nat. 
Mus., 1881, 242 (Puget Sound, St. Paul, Humboldt Harbor, Shumagins, 
Tliulink, Unalashka, St. Michael’s). Jordan and Gilbert, Syn. Fish. N. A., 
p. 826, 1882. Bean, Proc. U.S. Nat. Mus., 1883, p. 20 (Cualasbka). Jor- 
dan, Nat. Hist. Aquat. Anim., 1884, 188, pl. 52. 
Habitat.—North Pacific, south to-Puget Sound. 
This is a rather abundant shore fish in Puget Sound, and it seems to 
be still more common northward, being, in Alaska, a food-fish of some 
importance. 
Genus VII.—PSETTICHTHYS. 
Psettichthys Girard, Proc. Ac. Nat. Sci. Phila., 1854, 140 (melanosiictus). 
TyPE: Psettichthys melanostictus Girard. 
This genus contains but a single species, found on the coast of Cali- 
fornia. Itis nearly related to Hippoglossoides, but possesses the peculiar 
accessory dorsal branch to the lateral line, characteristic of so many of 
the Pacific coast flounders. 
ANALYSIS OF SPECIES OF PSETTICHTHYS. 
a. Body elliptical; mouth rather small; maxillary 23 in head; teeth large, sharp, 
uniserial ; eyes very small, 5 in head, separated by a broad, flat, scaly interspace; 
gill-rakers slender, X + 14; scales very small, ctenoid, adherent; accessory lateral 
line lone; first rays of dorsal exserted, the longest 3 in head; head 4; depth 24; 
D. 85, m! 60, Lat. 1. 112; vertebra 11-+29=40; color dark yen feos every- 
where finely speckled with darker ¢.2-.- 22. .234.-223 82. 2255-6 MELANOSTICTUS, 8.

Hippoglossoides melanostictus, Jordan and Gilbert, Syn. Fish. N. A., 1882, p. 828. 
Habitat.—Pacific coast of North America, from Alaska south to Mon- 
tery. 
This is one of the commoner flounders of the Pacific coast, being 
everywhere known by the name of “Sole.” It lives near the shore, and 
reaches a length of about twenty inches. 
In color this species is quite unlike the species of Hippoglossoides, 
hut in most other respects the two groups are closely allied.
