 Lwmonema YaiTellii, GOnther, Cat. Fish. Brit. Mus., iv, 356 (with a full iloscriptiDii). 



A Lwrnoncma with slender body, and with the anterior rays of the first dorsal pro- 

 longed as long as the head. Veutrals prolonged, but not reaching- to origin of anal. Anal 

 emarginate, angular behind. Scalessmall, about 110 in the lateral line and 8 series above it. 



Radial formula, D. 5, 59-60; A. 59-60. 



Color, reddish-gray. Vertical fins black with white blotches. 



This form is known only from Madeira, where it lives at great depths far from the shore, 

 and is exceedingly rare. 



LWMONEMA ROBUSTUM, GOnthek. 



Lwmonema robustitm, Gunther, Cat. Fish. Brit. Mus., iv, 1862, p. 3.57. — Vaillant, Exp. Sci. Travnilleur et 

 Talisman, 1888, 286. 



A Lwmonema having the anterior rays of the first dorsal iirolonged; ventral extending 

 to the eleventh anal ray. About 130 scales in the lateral line, and 13 series between tlie 

 anterior dorsal and the lateral line. 



Eadial formula, D. 5,53; A. 47. 



This form, first obtained at Madeira, and described by Giintlier in 1SG2, was found by 

 the Fi-ench Expedition at considerable depths oft' Morocco and the Cape Verde by the Tra- 

 vuilleur, Station xxsvni, 1882 in C36 meters and the Talisman, Station ex, cxi, cxiii, in 460 

 to 760 meters. 



LiEMONEMA BARBATULA, Goode and Bean. (Figures 315-315, A. Young.) 



Lmmonema barhitula, Goode and Bean, Bull. Mus. Comp. Zool., x, 1883, 204. 



A Lwmonema having head contained in body (without caudal) 4§ times; height of body 

 4.J times. Diameter of orbit in length of head 3 times, upper jaw a little more than twice. 

 Barbel half as long as the diameter of the eye. Vent situated under the sixth or seventh 

 ray of second dorsal. Distance of first dorsal from snout equal to one-fourth standard leng t li 

 of body. The base of the first dorsal is half as long as the middle caudal rays; that of the 

 second, slightly more than 3 times the length of the head. The first dorsal is composd of 5 

 rays, the first of which is elongate, 3 times as long as the middle caudal rays; it extends to 

 the base of the twenty-fourth ray of the second dorsal. Anal fin iusertc^d at a distance from 

 the tip of the snout equal to twice the length of the head, its distance from the insertion of 

 tlie veutrals being equal to the length of tlie head. The length of the veutrals is equal to 

 that of the pectorals, their tii)S not extending to the vent. 



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

 on the posterior part of the body. 



Itadial formula: B. VTI; I). 5-03; A. 59; P. 19; V. 2. Scales 13-140-31. 



Color similar to that of the various species of P/zf/m'; the dorsal and anal tins iiave nar- 

 row black margins. 



The length of the first dorsal ray is very variable in Individuals, being shorter in younger 

 specimens. 



This species differs from L. YarrcUil by its much smaller scales, and Irom //. rdlnistnm 

 by the greater number of rays in the dorsal and anal tins and its much shorter veutrals.
