USNM 135517, Albatross station 5287, lat. 13°37'40" N., long. 

 120°39' E., depth 379 fathoms, July 20, 1908, 5 specimens, 26 to 

 31 mm. 



Distinctive characters: This species, without the group of supra- 

 anal photophores but with 11 to 15 anal ones, has an unusually small 

 number of gill rakers (a total of only 10 to 12 on the first arch); the 

 posttemporal spine is long, slender, and simple and its length is always 

 greater than the diameter of the pupil. The greatest depth is twice 

 the standard length. 



Description: Counts made are given in table 1, p. 591, and table 

 6, p. 636. 



Color: The color pattern is shown in figure 20, p. 631.

 its length shorter than the diameter of the pupil; the gill rakers on 

 the first arch total 21 to 24, usually 22 or 23; anal photopores total
