very fat. As a pniifisli it ranks \('r,\ lu^li, being seareely inferior to 

 the eulachou. The Ilypomesus olirhis of Kauitscliatka lias been shown 

 by Dr. Bean to be a different species, si)awninj2: in flesh waters. 



62. Thaleichthys pacificus (Kicliurdsou) Grd. — Ealaclion ; IlooJaldn ; CatnUe-Jinh ; 



Grea.ie-fnli ; Smell. 



Froni Oregon northward, ascending- the livers in spring in enormous 

 numbers, but not for a great distance. It is especially numerous in 

 Frazer's River and Nass River, and very many ascend the Columbia. 

 The run m Frazer's River takes place in May. They are exceedingly 

 fat, and when dry are said to burn like a candle. On Nass River is a 

 factory for the manufacture of eulachon oil, intended as a substitute 

 for cod-liver oil. The fact that eulachon oil is semisolid or lard-like at 

 ordinary temperature is a seiious hindrance to its salability for this pur 

 ])ose. When fresh, the eulachon is one of the very finest of pan-fishes, 

 and many of them are sent to the markets of Victoria. Pickled eu- 

 lachons are sent to San Francisco. It reaches a length of a little less 

 than a foot. 



63. Osmerus thaleichthys Ayres. — Smelt. 



From Monterey northward ; rather common, but not in such great num- 

 bers as rhe surf-smelt and the eulachon. It is smaller and less valu- 

 able than these. Little distinctive is known of its habits. Those brought 

 into market are usuallj^ soft, and are less salable than the spurious 

 "smelt," -AfAerino/j.s'fs', with which they are often mixed. It is rarely 

 luore than 6 inches in length. 



64. Osmerus atteiiiiatiis Lockiugton. — SmcK. 



Everywhere found with the preceding and scarcely less common. 

 Nothing distinctive is known of its habits, and it may ])Ossibly turn out 

 to be the female of the same species. 



Family ALEFIDOSAl RID.E. 



65. Alepidosaurus borealis Gill. — Iland-snw Fish. 



Puget Sound and northward, in deep water; cast on shore by storms. 

 A head from Puget Sound in the Museum of the California Academy of 

 Sciences, and another from the Aleutian Islands in the Museum of the 

 Alaska Commercial Company. 



Family PAEALEPIDiE. 



G6. Sudis rmgens Jordan & GilbRil. 



Known only from one specimen, about 8 inches in length, from t lu- 

 st omach of a 3Ierlucms, itself in the stomach of an Ornjnm a(al(>n;ia. in 

 Santa Barbara Channel. 



67. Paralepis coruscaas J. & G. 



One specimen obtained at Port Townsend, Wash. It is very close to 

 FaraUpis borealis Keinh. from Greenland, if not identical with it.
