tripterus marmoratus Bean. Several small specimens were secured at stations 3224, 3257, 3258, and 3311, inBering Sea, north of Unalaska Island; depths, 70to 121 fathoms. They agree withthe types in having but 14 dorsal spines, the first four of which are not noticeably dif-ferentiated. The second dorsal contains 11 or 12 rays, and the anal fin 13. The lasttwo rays of the anal fin are approximated at base, but do not evidently constitutea divided ray. 48. Psychrolutes zebra Bean. Taken abundantly in shallow water south of the Alaskan Peninsula, thence westto and through Uuimak Pass, along the northern shore of Unalaska Island, and inBristol Bay. The depths range from 31 to 121 fathoms, at stations 3213, 3215, 3216,3217, 3219, 3222, 3223, 3224, 3225, 3257, 3258, 32.59, 3263, 3265, 3272, 3310, 3311, 3313,3322, and 3334.
