BULLETIN OF THE BUREAU OF FISHERIES. 



Body slender; head broad, depressed, flat above; snout flat, projecting a little over the broad mouth; 

 lower jaw included; maxillary reaching vertical from posterior margin of pupil; nostril single, in a 

 slender tube; teeth fine, conical in narrow bands in each jaw; gill opening small, restricted to the area 

 above the pectoral fin. 



Dorsal beginning a short distance behind pectoral; anal beginning under sixth dorsal ray; dorsal 

 and anal joined to caudal for 0.25 its length; caudal slender, 1.2 in head, composed of 10 rays. Pectoral 

 broad, not notched, the rays progressively shortened, the anterior rays free nearly to base; longest 

 pectoral rays reaching to opposite origin of anal. Vent about midway between tip of lower jaw and 

 anal fin. 



Color dusky, paler posteriorly; abdomen, pectorals, interorbital space, snout, and the lower part 

 of the head darker; in life dusky reddish throughout. 



Three specimens were taken, one from station 4761, off the Shumagin Islands, depth 1,973 fathoms; 

 the other two from station 4797, off Staritschkof Island, Kamchatka, depth 682 fathoms. 



BATHYMASTERID^. 

 Bathymaster signatus Cope. 



Many specimens were examined, averaging about 30 cm. long. All were similarly colored in 

 life, as follows: Light olive-brown, becoming whitish on belly and posterior part of mandibles; a nar- 

 row yellow streak on anterior orbital rim, a second along entire preorbital border, a third along edge 

 of gill membrane; mucous pores on head bright scarlet, including the series along preorbital border, 

 3 or 4 on preopercle and 3 on opercle in a horizontal series on level of eye; gill membranes mesially 

 blackish blue; dorsal brownish on basal part, light straw-yellow on marginal portion, a black blotch 

 always present on anterior rays; caudal colored like dorsal; ventrals, anal, and lower pectoral rays 

 blackish blue; upper pectoral rays with the distal half light yellow. 



In a specimen 248 mm. long to base of caudal, the head is 29.5 hundredths of the length; diameter 

 of eye 7.5; interocular width 5; length of maxillary 14; distance from nape to front of dorsal 5; length 

 of gill-raker 2; depth of caudal peduncle 7; length of caudal 16.5. 



Series of canines in jaws very strong, the symphyseal band narrow. 



List of St.wions. 



Specimens taken as above on Petrel Bank and the Komandorski Plateau. 



Bathymaster cseruleofasciatus, new species. (Fig. 29.) 



Type 235 mm. long, from Agattu Island, Aleutian chain. 



Differing from B. signalus in the coloration, the shorter, less numerous gill-rakers, the fewer pec- 

 toral rays, the smaller head with maxillary longer in proportion, the smaller eye, smaller teeth, deeper 

 caudal peduncle, and more anteriorly inserted dorsal fin. 



Measurements of type in hundredths of length without caudal: Length to base of caudal 209 mm.; 

 length of head 28 hundredths; length of snout 7; diameter of eye 6; length of gill-raker i; width of 

 head 14.5; interocular width 4; length of maxillary 15; distance from nape to front of dorsal 6.3; from 

 snout to front of dorsal 23.5; from snout to ventrals 23.5; from snout to anal 45; depth of body 19; depth 

 of caudal peduncle 8.5; length of pectoral 20; length of ventral 12.5; length of caudal 13; longest dorsal 

 ray 12; longest anal ray 8.5.
