ef[ual to one fourth standard length of body. The base of the first dorsal is 

 half as long as the middle I'audal rays ; that of the second, slightly mure than 

 three times the length of the head. The hrst dorsal is composed of live rays, 

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

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

 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 equal to the length 

 of the liead. The length of the ventrals is equal 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 [lart of the body. 



Eadial formula : B. VII ; D. 5-63 ; A. 59 ; T. 19 ; V. 2. 



Scales 13-140-31. 



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

 fins have narrow Ijlack margins. 



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

 shorter in younger specimens. 



This species difters from L. Yarrcllii 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 c5f this species were obtained at the following stations of the 

 steamer " Blake."

A single specimen Avas also obtained by the Fish Commission steamer " Fish 

 Hawk" in Lat. 38° 35' N., Long. 73° 13' W., at a depth of 312 fathoms, Oct. 

 10, 1881 (U. S. Nat. Mus., No. 29,04(3).
