the vent in both sexes, reaching in males to or nearly to the front of anal. Pecto- 
rals usually with 21 rays, the lower 7 simple, thickened, exserted, 2 or 3 of them 
‘often as long as or longer than the branched rays above, the fin thus appearing 
‘notched or lobed. The longest rays extend well beyond front of anal, and are con- 
“tained 1} to 1} times in head. Caudal fin very sharply and deeply forked, especially 
in male specimens, where the median rays are but half the length of the longest 
‘ones. The caudal varies in length from five-sixths length of head (in males) to two- 
‘thirds length (in females), and contains 11 rays, the lowermost (corresponding to 
‘the uppermost developed ray) shortened and unbranched, as in Triglops. 
Coloration similar in the two sexes. Light-brownish above (in spirits), the back 
“erossed with the usual four saddle-shaped blotches; the first one broad, under the 
‘first seven or eight dorsal spines; the second narrow, under the fifth to the tenth 
rays of second dorsal; the third and fourth very narrow, under last dorsal rays and 
‘on back of caudal peduncle. Between the second and third bars are two or three 
‘similar fainter ones equally dividing the interspace. The bars are continued to 
“below the lateral line, where they immediately fork, giving rise thus to a series of 
‘vertical dark blotches mostly arranged in pairs; the interspaces between some of 
‘the anterior pairs are provided each with a bright silvery spot. Under side of head 
‘and body whitish, the breast and anterior part of belly more or less silvery. Lining of 
sopercle jet-black, the color descending onto the uppermost branchiostegal rays. An 
‘ill-defined dark blotch below eye, from which runs a narrow streak along preorbital 
‘to front of snout, where it crosses upper lip. Lower lip black, except laterally. No 
distinct markings on basal portion of pectorals; a small faint spot at base of its 
upper rays, and a number of very faint bars sometimes visible in females. Males 
‘with two conspicuous jet-black bars crossing terminal half of the lower thickened 
‘pectoral rays. Tips of the narrow caudal lobes jet-black; no other markings visible. 
' Several specimens, from 115 to 245 mm. long, from stations 3213, 3214, and 3222, 
‘south of Sannak and north of Unimak Islands, at depths of 38 to 50 fathoms.

‘ The elongation of the lower exserted pectoral rays and the “serrations” (i. e., 
‘minute spinous scales) on the fin rays are characters which Prionistius shares with 
‘other related forms. The slenderness of the body, the emarginatiou of the caudal 
‘fin, and the elongate dorsal and anal fins are also present in Klanura forficata, where 
‘the two former characters are carried to an extreme. The characteristic features of 
| Prionistius are the naked breast and the absence of the usual series of enlarged 
“plates along base of dorsal fin. 
| Four specimens, 77 to 87 mm. long, were secured at stations 3214, 3218, and 3223, 
‘south of Sannak and north of Unimak Islands, Alaska, at 38 to 56 fathoms. The 
‘ventral fins seem to be not more advanced in position than in the other species. 
‘In other respects our specimens agree well with Dr. Bean’s admirably full description.

(75. Hemilepidotus jordani Bean. 
) Taken abundantly in most iocalities visited, with hand lines at Unimak Island, 
‘Amak Island, and Unalaska Island, and with beam trawl both north and south of 
jthe Alaskan Peninsula and the Aleutian Islands, at stations 3213, 3214, 3215, 3217, 
13220, 3222, 3259, 3262, 3266, 3281, 3291, 3292, 3294, 3322, and 3333, at depths of 19 to 50 
fathoms. The fin rays range higher than in the types, as shown by the counts in 
seven specimens.
