222 EXPEDITION OF THE "ALBATROSS," 1899-1900. 



more divergent, but not markedly so; interval between third and fomtli 

 pairs shortest, that between fourth und lil'th l)ut slightly longer; second 

 interval but little shorter than the first. Supra-ventrals slightly nearer 

 ventral fins than lateral line. First pair of ventral photophores nearly in 

 contact on median line, the others farther apart and equidistant from 

 median line, the fourth pair at the sides of the vent and somewhat an- 

 terior to it; second interval longest, the first shortest. Upper supra-anal 

 immediately below lateral line on its seventeenth scale, and in a vertical line 

 passing through the second anal ray ; middle supra-anal slightly nearer 

 upper supra-anal than fourth ventral, in an oblique line joining the two; 

 lower supra-anal below and well in .advance of middle supra-anal, in a 

 line joining middle supra-anal with first ventral. Antero-anals 7 .(6 in one 

 .specimen), equally spaced, forming a gently curved line with the concavity 

 downwards. Postero-lateral immediately below lateral line, above or slightly 

 behind last antero-anal. Postero-anals 5. Precaudals 2, in an obli(jue line, 

 the interspace a little wider than that separating those of anal series. 



In the four specimens before us, the anal photophores number as follows: 



^7+5 ^7 + 5 ^7 + 5 ^G + 5 

 ^7+5,^7 + 5,^7 + 4,^0 + 5 



General color very light brown, marked with distinct blackish spots 

 distributed as follows: one immediately behind nape, one before donsal fin, 

 one at ba.se of adipose fin, — these all on median line; a humeral .spot; a 

 very small spot at base of caudal. 



It seems highly probable that D. naufragits Waite (Waite, Records Austra- 

 lian Mu.seum, 1904, 5, p. 154, pi. 18, fig. 3), should be placed in the synon- 

 oiny of this species, the differences indicated by the author being drawn 

 from the somewhat inaccurate drawing of the immature type of D. aspcr. 



Rhinoscopelus tenuiculus (G arm an). 



Myctophum tenuiculum (Jitrman, Mem. Miis. Coinp. Zool., 1899, 24, p. 262, pi. J, fig. 5. 



A single specimen, 50 mm. long, was taken September 4, 1806, in Lat. 

 N. 10' 57' 35", Long. W. 137^ 35' 25". The species is considered by Brauer 

 (Zoiil. An/.., 1904, 28, p. 390) to be a synonym of 11. ctjccii but comparison
