400 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



12. Nannobrachmm iiamiochir Gilbert. 



Tlic present status <>t" this species aiul its (listinetivc eliaracti'ra have lieeii dia- 

 cussed under the preceding fiiriM. Tlie correlated ditlereuces are so constant in our 

 specimens that they can not l»o ignored, yet are small in amount. They depend 

 neither on age nor sex. From among the original type specimens I select as specilic 

 type No. 1459 of the Lelaud Stanford .Junior Tuiversity Museum, from station S072. 



Specimens in the present collection from stations 3211, a307, 'S.iOS, 3327,332}), 3338, 

 3310, 3312, and 3348, including the entire North Pacific and Bering Sea, at depths of 

 313 to 1,625 fathoms. 



Famxly ARGENTINIDiE. The Smelts. 



13. Mallotus villosus (Miilha). Capeiui. 



Dredged in shallow water at three stations m l.ristol Bay, Alaska; 3235, 3238, and 

 3240, depths 11 to 18 fathoms. 



14. Thaleichthys pacificus Richardson. Eulachon; Candle-fish. 



A single line spccim<sn of the candle-fish was taken near the mouth of the Nushagak 

 River, June 3, 18SI0. 



15. Osmerus deiitex Steiudachner. Rainbotv Herring. 



Occurs abundantly in the Naknek and Nushagak rivers, and forms au important 

 part of the food supply of the natives. At the time of our visit (June 1-3) it was 

 running rather sparingly. Specimens were secured with the seine in both of the 

 above-mentioned rivers, and in the trawl at station 3231, in Bristol Bay, deiith 12 

 fathoms. 



16. Osmerus thaleichthys Ayres. 



Several young si)ecimens, probably to be referred to this species, were taken in 

 the Nushagak River near its mouth. They exhibit the characteristic weak dentition 

 of this form, the teeth being barely perceptible on jaws, vomer, and tongue. The 

 scales number 55 and 58 in the course of the lateral line, and the anal rays 14 and 10. 

 The maxillary is short, scarcely reaching to below middle of eye. O. thaleivMhi/s has 

 not been previously reported from Alaska. 



17. Leuroglossiis stilbius Gilbert. 



One si)ecimen IVoul station 3330, olf the northern shore of Unalaska Island, at the 

 depth of 351 fathoms, and several mutilated examples taken from the stomach of a 

 Macrurus at station 3332, in 400 fathoms. The largest of these is 120 mm. long. 



Family SALMONIDiE. 



18. Coregonus laurettae Bean. 



A young individual, 125 mm. long, was taken at the mouth of the Nushagak River, 

 June 3. The lower jaw is very slightly longer than the upper; the eye is of mod- 

 erate size, 4J in head; the scales are rather large in size, 84 being present along the 

 lateral line; and the gill-rakers are long and numerous, 25 present on horizontal 

 limb. A similar specimen was taken in the Naknek River (sciles 87). 



19. Oncorhynchus goibuscha (Walbaum). Tlmnphack Salmon. 



The humpback salmon was 8<!cn by us at Port Moller, on the northern side oi' the 

 Alaskan peninsula, during two visits which included the first two weeks and the last 

 week of July. During the first part of this month they were running in small num- 

 bers, and as a few scattering ones only had been taken at Unalaska up to .lune 10, it 

 is safe to indicate the 1st of July as the beginning of their appearance on that part 

 of the coast. In the early part of their run they proved a very acceptable table 

 fish, but later they rapidly deteriorated. On our return to Unalaska, .July 31, wo 

 learned that tlu^y had been running for several weeks, and during several visits in 

 the month of August they were found in incredible numbers crowding into the
