fathoms; and 5677 in 735 fathoms, probably represent the same species, 

 but are not in condition for definite specific determination. Approximate 

 latitudes of these stations run from 33° to 25°, depths from 451 to 868 

 fathoms. 



Color, fresh, black (station 5685). 



Plectromus [Melamphaes] lugubris Gilbert 

 Two of about 3% inches total length from station 5683 in 630 fathoms 

 off Cape San Lucas, approximate latitude 23°. 



Sebastolobus alascanus Bean

 Numerous specimens from station 5694, off the Santa Barbara 

 Islands, approximate latitude 33° in 640 fathoms. 



Sebastolobus altivelis Gilbert 



Numerous specimens from station 5693, off the Santa Barbara 

 Islands, in 451 fathoms (approximate latitude 33°). One from station 

 5683, off Cape San Lucas, 630 fathoms (approximate latitude 23°). 



It would seem from the above that, for the same latitude, altivelis 

 occurs in shallower water than alascanus. 



There is also Sebastolobus material from several other stations show- 

 ing intergradation between the two forms. From station 5695 (approxi- 

 mate latitude 34°), off the Santa Barbara Islands, in the intermediate 

 depth of 534 fathoms we have two typical altivelis, two specimens which 

 are altivelis except for having sixteen dorsal spines, characteristic of 

 alascanus, one is an alascanus except for fifteen dorsal spines character- 

 istic of altivelis, and another with fifteen spines has the longest spine 

 of intermediate length. 



From station 5696 (approximate latitude 35°) north of Point Con- 

 ception, in 440 fathoms, eight specimens are referable to altivelis, but 

 one has sixteen spines, two others have the longest spine 2.2 and 2.3 in 

 head respective]}^ which is a little short for that species. 



On the other hand, three specimens from station 5699 (approximate 

 latitude 36°) , south of Monterey, California, in 659 fathoms, are inter- 

 mediate, dorsal spines 16 in one, 15 in two, the longest spine 2.3 to 2.4 

 in head. A specimen from station 5697 (approximate latitude 36°) in 

 485 fathoms has dorsal XV, spine of intermediate length. 



Of two specimens from station 5698 (approximate latitude 36°), 

 south of Monterey, in 475 fathoms, one is an altivelis, the other an
