The pyloric caeca in this species are small, numerous, about 35 in 

 number. The ventrals have 10 or 11 rays; branchiostegal rays, 7. 

 The bands of teeth are villiform rather than cardiform, as originally 

 described, the band rather wide, a distinct outer series of canines in 

 upper jaw. 



Scales largely fallen in all specimens, the few remaining showing 

 that those on top and upper part of sides of head and on breast bear 

 several (usually 4 or 5) parallel or weakly diverging series of spinules; 

 scales of adjacent areas may show faint ridges, the others are smooth, 

 unmarked. 



LYOPSETTA EXILIS (Jordan and Gilbert). 



Nothing is known concerning the southern limit of this species. 

 It is very abundant along the coast of California, and has been 

 dredged by the Albatross off the coasts of Oregon and Washington, 

 British Columbia, and southeastern Alaska as far north as Wrangell. 

 The depth is known to range from 40 to 200 fathoms. 



The dorsal rays range from 77 to 85, most frequently 80 or 81; 

 anal rays from 59 to 65, most frequently 61 or 62. There are usually
