no. 2075. FISHES FROM SOUTHERN CALIFORNIA— GILBERT. 



341 



spines inconspicuous, their tips acute, not cleft; upper preopercular 

 spine rather slender, of moderate length, with three short backwardly- 

 hooked barbs in addition to the terminal spine; preopercular margin 

 below with three sharp spines, the upper directed backward, the 

 lower downward and forward; no spinous point on subopercle; 

 occipital ridge short, rugose, not ending in a free spine; sensory 

 canals and pores on head much larger than in any other species, in 

 accordance with its deeper habitat; the pair of pores below the 

 mandibular symphysis open into a common pit with slightly raised 

 margins. 



Dorsal series of plates shorter than in related species, beginning 

 under middle of spinous dorsal and ending a little in advance of end 

 of soft dorsal, the last few plates being single; no plates on back of 

 caudal peduncle; the dorsal row contains 20 to 22 plates. Lateral 

 line with 36 large pores. No plates behind axil of pectorals. 



Spinous dorsal low, none of the spines produced, a very short inter- 

 space between the dorsals. Pectoral wider than in other species, 

 with 18 rays, reaching slightly beyond the vent; ventrals extremely 

 short, not exceeding the diameter of the pupil, composed of 1 spine 

 and 2 rays, as always in this genus; caudal broadly rounded. 



Dusky olive throughout, but little lighter below; from base of soft 

 dorsal 2 broad black bars descend to below the lateral line, the 

 anterior sending a narrow prolongation forward from the lower 

 anterior angle; a less evident black bar extends downward and 

 forward from the spinous dorsal. Soft dorsal black, with a narrow 

 white edge and a small light area at base above the interval between 

 the black bars; 2 vertical black bars on spinous dorsal, the interval 

 light; caudal black, with a narrow white margin; pectoral black, a 

 lighter area at tips of upper rays and a broad light half -bar descend- 

 ing almost vertically from base of upper rays; the shortened lower 

 rays are light, as are the tips of all the rays ; ventrals dark. Occipital 

 filaments black, maxillary filament white. 



The paratypes are smaller than the type and much lighter in color, 

 all the fins translucent with darker bars and mottlings, the pectoral 

 with a large black blotch on lower half; an evident Y-shaped dark 

 mark at base of tail.

RADULINUS ASPRELLUS Gilbert. 



This species has been dredged previously by the Albatross at 

 numerous stations off the coasts of Washington, Oregon, and northern
