THE LANTERN FISHES. 237 



Minute scattered photophores on head and body, but the integument largely 

 rubbed off, so these are now visible infrequently and are not represented in 

 the drawing. Luminous scales can be made out only on upper and lower 

 sides of caudal peduncle, but such were probably present at base of veiitrals 

 and of anterior dorsal and anal rays. 



Short luminous patches on upper and lower margins of caudal peduncle, 

 not extending more than one- third distance from caudal rays to anal and 

 adipose fins. 



Paired fins broken, their length uncertain ; ventrals inserted a trifle 

 behind origin of dorsal ; anal originating sliglitly behind last dorsal ray ; 

 adipose dorsal over last anal rays. 



A single small specimen in poor condition. 



Vinciguerria lucetia (Garman). 



Maurolicus lucetius Garman, Mem. Mus. Comp. Zool., 1899, 24, p. 242, pi. J, fig. 2. 



Several small specimen;?, in poor condition, from Hydrographic Station 

 3798 (A. A. 27), near the Marquesas Islands. It is not clear in what respects 

 this spe.cies differs from typical V. aitenuata (Cocco) from the Atlantic, as 

 characterized by Lutken and Bellotti (see Llitken, Spolia Atlantica, Scope- 

 lini, 1892, pp. 270-2). In its slender habit, posterior anus, and the limita- 

 tion of silvery pigment to the preanal region, as also in the somewhat smaller 

 number of photophores, it agrees with aitenuata. On the other hand, 

 Zcdarges nimbariiis Jordan and Williams (Proc. Cal. Ac. Sci., 1895, ser. 2, 5, 

 p. 793, pi. 76), a true Vinciguerria, agrees with V. poiveriae (Cocco) from 

 the Atlantic in its deeper form, anterior position of anus, the extension of 

 the silvery pigment to near the base of the caudal fin and the increased 

 number of photophores. Llitken was unable to distinguish attenimta and 

 poiver-iae on the examination of a large amount of material. If his conclusion 

 is valid, it may well prove that lucetia and nimbaria are the Pacific represen- 

 tatives of a variable and widespread species for which the name attenuata 

 must be used. The dorsal fin contains 14 rays in the types of Z. nirnbarius, 

 not 9 as given.
