32977. (44.) Young. Saint Michaels, October IS, 1877. [D. 83 or 84.] 



Specimen seven inches long. Ground color of body dull white, with a fleshy tint, becoming 

 silvery on the head. The pattern of marking consists of an irregular series of very dark brown, 

 nearly black, blotches of varying size, but usually large and irregular shape, and separated by a 

 network of the Hght ground color on the anterior third of body, except the abdomen,which is dull 

 olive-brown, the caudal portion, occupying a little over one-half the length of the body, has 

 the blotches changed to a series of longitudinal stripes of dark and light- five of the former and 

 four of the latter. The upper and lower dark stripes border the dorsal and anal fins. The two 

 dark stripes next the central one disappear near the caudal peduncle. The width of the dark bands 

 varies, especially the central one, which shows alternating rounded expansions and contractions. 

 Pectorals black, with a light spot on upper part of basal portion, from which extends an indistinct 

 rectangular dark spot upon the anterior face of flu on each side of the' anal. On the sides 

 of the abdomen, and surrounding it to the white spots in front of the vent, as well as on the 

 ventral surface of the caudal peduncle, is the same dark grayish olive as on the back, but nearly 

 hidden and obscured by numerous and very minute punctulations. Fins: Ventrals very dark 

 brownish, nearly black at tips, with about a half dozen white spots of large size on outer half. 

 Anal translucent, but nearly entirely obscured by an overlying layer of punctulations, which only 

 leave a few spots free; the tip and the clear spots have a golden tint. Caudal transparent, with 

 a golden tint, more decided on the rays near the tip. The ground color is overlaid by a dark 

 irregular band, extending across the end and sending slight arms into the middle of the fin, partly 

 inclosing clear spaces. First dorsal black, with one or two transparent spots. Second dorsal 

 colored like the tail, but the dark mottling is spread over the entire fin, inclosing the clear spaces 

 in the form of spots. Pectorals a clear golden yellow, crossed by a wide, irregular anastamosing 

 jet-black band, which occupies nearly half the fin and divides the transparent ground into spots, 

 bars, and blotches. 



Beaohtopsis dodecabdeus (Tiles.). Angled Sturgeon-flsh. (Plate XVI, Fig. 1.) 



32967. (237.) Unulakleet. [D. ix; 7; A. 13.J 



Specimen from fresh-water creek at TJnalakleet, close to the sea. Another specimen of this 

 fish was taken from the stomach of a large seal (MuHuTc). Color of upper surface and sides a 

 pale dingy watery olive-brownish. Below white. 



First dorsal, nine spines, with bar of blackish brown covering oue-fourth the fln along the upper 

 or distal border. A second bar of the same divides the fln longitudinally in half and parallel to the 

 other bar but narrower. Second dorsal, seven rays, with the dark markings of the flrst dorsal 

 repeated in an indistinct way; excepting the dark markings both fins are transparent. Pectorals 

 translucent, with four series of black spots upon the rays as follows : The first row occupies the 

 rays near their distal ends, and then follow three other series, dividing the fln into fourths very 

 equally. The inner series is nearly obsolete. Yentrals of two rays with a narrow dividing mem- 

 brane nearly black. Anal thirteen rays. The posterior four with membrane covered with a dark 

 blotch; the rest translucent. Tail dark olive-brown or blackish, paler nearer body. -
