 2 dorsal fins and 1 anal, the anterior dorsal composed of 5 rays; ventrals reduced to a

L^MONEMA YAERELLII, (Lowe), Gunther. 



Phycis Yarrellii, Lowe, Syn. Fish. Mad. (Trans. Zool. Soe., n, 100); Fishes of Madeira, 43, pi. vn. 

 Lcemonema Yarrellii, GtJNTHER, Cat. Fish. lirit. Mils., iv, 350 (with a full description). 



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

 longed as long as the head. Ventrals prolonged, bat not reaching to origin of anal. Anal 

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



Radial formula, D. 5, 59-60; A. 50-60. 



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



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

 and is exceedingly rare. 



LiEMONEMA ROBTJSTFM. Guntiier. 



Lfrmonema robustum, Gunther, Cat. Fish. Brit. Mus., iv, 1802, p. 357. — Vaili.ant, Exp. Sci. Truvailleur if 

 Talisman, 1888, 286. 



A Lcemonema having the anterior rays of the first dorsal prolonged; ventral extending 

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

 anterior dorsal and the lateral line. 



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



This form, first obtained at Madeira, and described by Guntiier in 1862, was found by 

 the French Expedition at considerable depths off Morocco and the Cape Verde by the Tra- 

 vailleur, Station xxxvni, 1882 in 636 meters and the Talisman, Station ex, CXI, cxiii, in 460 

 to 760 meters. 



L/EMONEMA BARBATULA, Goode and Bean. (Figures 315-315, A. Young.) 



Lamonema barbntida, Goode and Bean, Bull. Mus. Comp. Zool., x, 1883, 204. 



A Lcemonema having head contained in body (without caudal) 4~ times; height of body 

 4i 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 st andard 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 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 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 head. 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 part of the body. 



Radial formula: B. vii; D. 5-63; A. 59; P. 19; V. 2. Scales 13-140-31. 



Color .similar to that of the various species of Phycis; the dorsal and anal fins have nar- 

 row black margins. 



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

 specimens. 



This species differs from L. Yarrellii 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.
