crossed by narrow, dusky bars, formed by series of dark streaks on the 

 rays; mouth whitish; gill cavity silvery white, with the exception of the 

 lining of the opercle and the outer half of brauchiostegal membranes, 

 which are dusky. This is the Pacific representative of the Atlantic 

 Tii(/h2is ])'mgeU, from which it diifers in the greater slenderness of the 

 body, iiarticnlarly of the caudal peduncle, in the somewhat smaller eye, 

 the more pointed snout, the less fine subdivision of the lateral folds, the 

 less complete investment of the fins with prickly scales, and, above all, 

 in the peculiar coloration of the male. Alaska to Puget Sound ; taken 

 very abundantly by the Albatross at stations located both noi'th and soiith 

 of the Aleutian Islands and in Bristol Bay ; also from about St. Paul Island 

 in 24 to 37 fathoms, off Karluk in 31 fathoms, and off Eobben Island in 

 18 fathoms, and by Mr. Starks in Puget Sound, the depths ranging from 

 lOi to 42 fathoms ; specimens 82 to 140 mm. in length. (Gilbert). (Named 

 for Dr. Tarleton Hoffman Bean.)

Head 3^ to 3i ; depth 5f to 5+. D. XI-21 to 23 ; A. 22 to 24 ; P. 19 (18 on 

 left side iu 2 specimens) ; V. I, 3; C. 12-12-12; lateral line 46 or 47; bran- 

 chiostegals 6. Body very robust, the ujjper profile descending rapidly from 

 front of dorsal in a regular curve to tip of short snout; least depth of 

 caudal peduncle ii to 4f in its length from base of last anal ray. Head of 

 moderate length, its width I* to 2 in its length; maxillary reaching to or 

 nearly to vertical from middle of pupil, 2^ to 2J in head ; mandible slightly 

 projecting. Teeth on jaws and vomer, none on palatines; 2 blunt spines 

 on occiput. Eye very large, 1+ times the interorbital width, and 2^ in 

 head. Preopercle armed with 5 small spinous points, the upper one point- 

 ing upward and backward, the second and third backward, and the lower 

 2 pointing forward; opercle ending in a triangular spine. Branchiostegal 

 membranes broadly united, free from the isthmus posteriorly. The upper 

 part of the body and the top and sides of head, including all of cheek, 

 the lower, anterior, and upper parts of eye, and exposed portion of the 

 maxillary, thickly covered with prickly plates, much larger, more spinous 

 and scale-like than in Trujlops phuidi, and on sides loosely arranged in 

 series. Spines and rays of dorsals, caudal, and pectoral fins covered with 

 series of jnickles nearly to their tips, except the lower thickened rays of 

 pectorals, which are naked; a row of enlarged plate-like scales along the 

 lateral line, becoming very indistinct posteriorly, more numerous and less 

 distinct than in Trvjlops phujeli, 38 in number to opposite the last ray of 

 second dorsal ; a similar series along the base of dorsal fins, ending oppo- 

 site the posterior part of second dorsal ; lower half of body crossed at short 

 intervals by transverse undulating folds of skin, about 180 in number, the 

 edge of each fold with small rough scales causing it to appear sharply and 

 finely serrate, these scales much larger and more spinous than in TrU/lops 

 pingdi, those of successive folds meeting and overlapping; the folds reach-
