atiiies (Steindachner apparently saw none on palatines). A single bar- 

 bel of variable length (sometimes twice as long as, sometimes less than 

 diameter of orbit) at tip of lower jaw. Gill membranes united behind, 

 free from isthmus. First dorsal with 12 pairs of plates between it and 

 the occiput; anal long, beginning under middle of first dorsal; caudal 

 about 3 times as long as wide at base; pectorals long, 5f to 5 in 

 body, width at their base about 4 in their length ; ventrals about 3 

 in pectorals and 4 in head in female, 2 in pectorals and 2f in head 

 in male. Color reddish or grayish brown with innumerable minute 

 black spots; ventral surface pale, from front of anal to caudal pro- 

 gressively darker with minute black spots; a dark band extends along 

 the side of snout, across orbit and preopercle, and along the side of body, 

 dying out posteriorly; anterior dorsal dusky, darker behind; second dor- 

 sal indefinitely cross-banded with short streaks of darker on rays ; caudal 

 dusky; pectoral pale, indefinitely banded with short streaks of darker on 

 rays; ventrals pale in both sexes; anal pale. Vertebral column (of a 

 single specimen) with 15 abdominal and 30 caudal (including hypural) 

 vertebras. North Pacific, south to Japan and Oregon. The specimens 

 here described from Bristol Bay (Coll. Albatross) ; Japan (Steindachner) ; 

 Arctic Ocean near Bering Strait (W. J. Fisher, Steindachner) ; Bering Sea, 

 Bristol Bay* (Gilbert); (Tareinsky Bay (Barrett-Hamilton); Port Clar- 

 ence, Alaska (Scofield). t A variable species. Length of longest specimen 

 examined by us 5| inches, (barbatus, provided with a barbel.)

t Mr. Scofield gives the following note on 6 specimens taken at Port Clarence, Alaska 

 averaging about 6 inches in length. We have compared them with specimens of P. bar- 

 bata | trom Bristol Bay, Alaska, and find our specimens have a much longer barbel "and 

 slightly longer pectorals. In all other points they appear to be the same. The barbel is
