alascanus (with longest dorsal spine 2.8 in head, but spines XV). Five 

 others appear to be alascanus, but these are small, averaging 3 inches 

 in length, and small specimens, of which we have a number from the 

 other stations, have been excluded from the above discussion, where 

 they might cause confusion due to our uncertainty regarding age changes. 



To sum up, north of Pt. Conception, coastwise in latitude 36°, 

 depths 475 to 659 fathoms, both species occur (at 475 fathoms) but inter- 

 mediates are the rule. South of Pt. Conception off the Sta. Barbara 

 Islands (latitude 33°) we find alascanus (described from Alaska in 159 

 fathoms) at 640 fathoms, intermediates at 534 fathoms, altivelis (described 

 from Alaska in 625 fathoms) at 451 fathoms; and we have a single 

 specimen of altivelis off Cape San'Lucas (latitude 23°) in 630 fathoms. 



Color, fresh, uniformly rose red. 



Zesticelus profundorum Gilbert 

 Two small specimens from station 5695, southwest of the Santa 

 Barbara Islands (approximate latitude 34°), in 534 fathoms. 



Liparis osborni, new species 

 The type (No. 8344, American Museum of Natural History) is our only specimen, 

 collected by the 'Albatross' Lower California Expedition of 1911, north of Pt. Concep- 

 tion, California (approximate latitude 35°), station 5696 in 440 fathoms. Head, 3%

in standard length; depth, 4#o; eye, h){ in head; snout, 3%; maxillary, 2Y 2 ; inter- 

 orbital, 3%; pectoral from its upper axil, 1%; length of disk, 3; longest dorsal ray, 

 3%] longest anal ray 3}{) cuadal, 2%. Dorsal with 44 rays; anal with 39. 



Body swollen in front of anal fin, thence compressed, slender, tapering backward; 

 nape gibbous, profile concave above eye; interorbital flat. Gill opening moderately 

 wide, its width equal to snout, extending for % of its length below upper edge of 

 pectoral. Lower rays of pectoral produced in a pointed lobe which reaches vent. Vent 

 equidistant from front of anal and front of disk. Dorsal and anal adnate to caudal 

 for % its length. Dorsal origin behind nape, almost directly over the membranous 

 tip of opercle. Caudal narrow, subtruncate, scarcely rounded at tip. Color in spirits 

 whitish, in life uniformly pink.
