20; 



equal to one fourth standard length of body. The base of the first dorsal is 

 half as long as the middle caudal rays ; that of the second, slightly more than 

 three times the length of the head. The first dorsal is composed of five rays, 

 the first of which is elongate, three times as long as the middle caudal ray- : it 

 extends to the base of the twenty-fourth ray of the second dorsal. Anal fin 

 inserted at a distance from the tip of the snout equal to twice the length of the 

 head, its distance from the insertion of the ventrals being ecpual to the length 

 of the head. The length of the ventrals is ecpial to that of the pectorals, their 

 tips not extending to the vent. 



Scales small, very thin, deciduous, crowded anteriorly. Lateral line not well 

 defined on the posterior part of the body. 



Kadial formula : B. VII ; D. 5-03 ; A. 59 ; P. 19 ; V. 2. 



Scales 1 3- 1 40-31. 



Color similar to that of the various species of Phycis ; the dorsal and anal 

 fins have narrow black margins. 



The length of the first ttorsal ray is very variable in individuals, being 

 shorter in younger specimens. 



This species differs from L. YarreUU by its much smaller scales, and from 

 L. robustum by the greater number of rays in the dorsal and anal fins, and its 

 much shorter ventrals. 



Specimens of this species were obtained at the following stations of the 

 steamer " Blake." 



A single specimen was also obtained by the Fish Commission ateamer " Fish 

 Hawk" in Lat. 38° 35' X., Long. 73° 13' W., at a depth of 312 fathom-.
