38 BULLETIN OF THE BUREAU OF FISHERIES. 



pectorals, and above and behind it a band of larger scales filling the area subtended by the posterior 

 half of the curved portion of the lateral line, all of these scales arranged in more or less definite series, 

 those of the posterior band in regular rows extending obliquely downward and backward from the 

 scales of the lateral line ; body elsewhere naked; head naked; scattered pores on top of head, preopercle 

 and preorbital; a series of 4 on mandible, the anterior near symphysis, but distinct from its fellow. 



Dorsals narrowly joined at base, the last spine less than half the height of the first ray and about 

 one-third the longest spine, the membrane joining first ray of second dorsal immediately above the 

 base; dorsal spines slender and greatly elevated, with deeply incised membranes, the tips in both 

 males and females provided each with a cleft membranous flap; third and fourth spines longest, 1.5 

 in head (in females 2.2); dorsal rays long and slender, the longest 1.6 in head; anal rays thickened, 

 the membrane incised; pectoral reaching to below ninth dorsal ray, the rays all simple, the lower 8 

 thickened, their membranes deeply incised; ventrals reaching to front of anal, or in females little 

 more than halfway to anal; caudal gently rounded; anal papilla long, reaching nearly to front of anal, 

 the vent immediately behind the base of the ventral fins. 



Color in life: Light olive above, tinged with salmon or pinkish; five or six crossbars downward 

 from back, somewhat irregular in size and shape, but usually narrowest at dorsal base, widening 

 downward to become confluent with their fellows, and then more or less broken and interrupted to 

 form marblings along the sides of the body; the first dark bar is tmder the spinous dorsal, the remainder 

 under the soft dorsal; the darker area comes frequently to bound roundish spots of the ground color 

 along dorsal outline, these spots extending less than half way to lateral line; dark bars most intense 

 immediately below the dorsal band of plates; both dark and light areas above lateral line marked 

 with light blue spots and streaks of various shapes and sizes, some of these at times forming a line 

 separating the dark and light crossbars on back; below lateral line are about 7 narrow vertical streaks 

 of brownish or yellowish brown, which narrow downward and reach almost to base of anal; they are 

 very irregular in size, number, and position, and may inclose round spots of light blue; under side 

 of breast and belly white ; a dark bar vertically downward from eye and a number of narrower radiating 

 streaks of light blue bordered with darker; a dark blotch on the membranes between the last two 

 dorsal spines, wanting in females; spinous dorsal translucent, the distal portions of spines yellowish 

 or brownish, the fin with many bright carmine spots or streaks; soft dorsal with g broad oblique bars 

 of brov\Tiish yellow or bro-wnish green with light blue intervals; anal fin dusky or bluish at base, becoming 

 light yellow toward margin; caudal with orange crossbars becoming light yellow toward tips of rays; 

 ventrals whitish in females, blue-black in males; pectoral with a wide pinkish or grange blotch on 

 basal portion of upper half or two-thirds of fin; in males, the lower thickened rays are largely dark 

 blue, the distal portion of upper ray with two or more irregular cross series of brown spots; in the 

 largest male (the type of the species), the lower pectoral rays, the ventral, the anal, and the lower 

 part of the caudal fin very dark, almost black. 



Specimens were taken at stations 4777, 4778, and 4779, on Petrel Bank, Bering Sea, at depths of 

 43 to 54 fathoms. 



In 10 specimens, including the type, 5 have dorsal ix, 28, anal 22; 2 have dorsal ix, 28, anal 23; 

 2 have dorsal ix, 29, anal 23; i has dorsal x, 28, anal 23. All have 16 rays in the pectoral fin. 



Rastiinus scutiger (Bean). 



Taken at stations 4784, off Attu Island, 135 fathoms, and 4790, off Bering Island, 64 fathoms. 



In well-preserved specimens it can be seen that delicate folds of the integument pass downward 

 frorn the posterior margins of the plates of lateral line, and usually disappear among the scales; a few 

 may reach the belly and join their fellows on the median line, and a few others may reach base of 

 anal fin. 



In our material the head is 25 to 27 hundredths of the length, the snout 8 to 9, and the orbit 11 

 to 12 hundredths. The Droportions are the same in material previously reported on (Gilbert, Report 

 U. S. Fish Commission, 1893, p. 415) from station 3339, south of tlie Alaskan Peninsula. In the type 

 the eye is said to be twice as long as snout and two-fifths the length of the head.
