reaching- about halt way to the lateral hue, and a ie,33 marked 

 tinge of brown along the ventral region. In the middle of the 

 body this colouring matter is nearh' absent, and the scales have 

 a bright silvery appearance. 



The luminous spots are arranged as follows : Caudal 5 (in 

 this respect differing from all other species of Scopelus and 

 affording a ready diagnostic character) ; postero-lateral i ; anai 

 S + 5 extendmg from origin of anal to midway between its 

 posterior end and beginning of caudal tin, medio-lateral (' supra- 

 anal " of Liitken) 3 in a line with the last of the ventrals and 

 lorming an oblique series ; antero-lateral, i between ventral fin 

 and lateral line ; abdominal 5 in a curved line ; thoracic 5, 3 ki 

 a line with mandibular and lower opercular, and 2 higher up in 

 tront of insertion of ventral ; pectoral 3, 2 immediately below 

 and I above insertion of pectoral fin ; opercular 2, the lower 

 situated behind the angle of the mouth in a line v/ith mandi- 

 bular ; mandibular 3, antorbital i, somewhat indistinct, on front 

 margin of the eye a little below nostril. 



Besides these luminous organs, there is a patcli of luminous 

 scales above and below the caudal region, and the snout is 

 covered by soft glandular tissue, probably luminous in functioo.
