of fisbes, all of which were received in excellent condition. Although 

 Captain Nichols made no special efl'ort to obtain all the species oc- 

 curring in the region traversed, he succeeded in making some very 

 important additions to our knowledge of the fauna. Eippoglossoides 

 Jordani, Pscttichthys melanosticfus, and Xiplmter mucosus have not pre- 

 viously been known to occur north of Puget Sound. Gymnacantlius 

 galeatus was recorded with certainty only from Unalashka. Sebastodes 

 'paucisinnis has had San Francisco as its northern limit. A new spe- 

 cies of Gobius was obtained in Departure Bay, and a scaled genus of 

 CrijptacantMdcc in Kingcombe Inlet, and at Wrangel. This goes to 

 show what uiight be brought to light by a systematic search of the 

 "waters of Alaska. 



It is due to Captain Nichols to say that no better-preserved lot of 

 fishes has been received from any other collector. 



1. Hippoglossus vulgaris Fleming. 



29147 (120) juv. Sitka, Alaska, Sept. 13, 1881. 

 Length of specimen, 11 f inches. D. 103 ; A. 79, the last ray in each 

 of these tius is double. The usual plumpness characteristic of Alaskan 

 halibut is maintaiued. 



2. Hippoglossoides Jordan! Lockiugton. 



29810 (90). Safety Cove, British Columbia, Aug. 4, 1881. 



Length 14 inches. D. 99; A. 77, the last four rays of each of these 

 fins being split. Teeth of upper jaw in two rows, the outer row having 

 stronger teeth. Lower jaw with one row of teeth. 



Taken in 16 fathoms of water. Not previously known to occur north 

 of Puget Sound. 



3. Psettichthys melanostictus Glrard. 



29809 (107). Wrangel, Alaska, Aug. 16, 1881. 

 Length 12^ inches. D. 81; A. 59. The first known instance of its 

 capture in Alaska. 



4. Limanda aspera (Pallas) Bean. 



29146 (110). Wrangel, Alaska, Sept. 13, 1881. 

 A single exami)le, 6^ inches long. On the eyed side are numerous 

 small black blotches, involving the dorsal, anal, and caudal as well as 

 the body. This species has the lemon color on the posterior part of the 

 blind side just as in L. fcrruginea. I have again compared aspera with 

 ferruginea, and find that they are certainly congeneric. 



5. PoUachius chalcogramnius (Pallas) Jordan & Gilbert. 



29126 (82). Head of Kingcombe Inlet, Brit. Col., Aug. 2, 1881. 



29127 (87). Head of Kingcombe Inlet, Brit. Col., Aug. 2, 1881. 



29128 (104). Wrangel, Alaska, Aug. 17, 1881.
