THE FUR SEALS OF THE PRIBILOF ISLANDS. 



plates. These plates are present in some of tbe females taken by the Albatross, but 

 are not so evident. The female has a few scattered rough prickles back of the origin 

 of the pectorals. The males have the mushroom like filaments behind the pectorals, 

 and the middle rays of the pectorals have papillie along their inner edge. 



25. Gymnocanthus galeatus Bean. 



Type locality: Unalaska. We took one small specimen (3| inches) at Point Bar- 

 row, Alaska. 



Fin formula: 9 , D., X, 15; A., 17; P., 18; V.,3. 



H., 3J or 3i%, including caudal; depth, 5J; Eye, 3J in head, to end of opercular 

 spine; snout, 4; maxillary, 2^ in head, reaching past posterior edge of pupil; interor- 

 bital width 2 in length of orbit; lat. line, 43 or 44. Fifth or sixth rays of pectorals 

 longest, reaching to third anal ray. Ventrals reach two-thirds distance to vent. 

 Mouth slightly oblique. Upper preopercular spine with three sharp points on its 

 upper side. No papilla; or sharp points under pectorals. 



26. Pallasina barbata (Stciiidachncr).

 and Japan.— Bean, Proc. II. S. Nat. Una. 1881, 248; Turner, Nat. Hist. Alaska, 94. 



Six specimens taken at Port Clarence, Alaska, averaging about G inches in length. 

 We have compared them with specimens of P. harhata from 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 one-third distance from tip of 

 lower jaw to edge of gill membrane. The two dorsals vary in their distance from each 

 other. In one specimen they touch, in the others they vary in distance the width of one 

 or two plates. The specimens show a sexual difterence. The females have shorter ven- 

 trals and a lower, smaller first dorsal than the males. The first dorsal, too, is without 

 color. The males have larger ventral fins and a lai'ge darkly colored first dorsal.

27. Pallasina aix Starks. 



Two small specimens taken at Chignik Bay, Alaska. 

 A., 10; P., 12; D., VII, G; A., «); P., 12. 



We have compared these specimens with the types of raUnsina aix and we can 

 find no good differences. One of our specimens has three median plates in the front 

 of the ventrals, the other two. (Our specimens of P. harhata have either three or two 

 median plates in front of the ventrals.) 



A few of the types have 12 pectoral rays, but the majority have 11.
