third supra-abdominal organs nearly in line, second is slightly below 

 them, the distance not more than half width of first. Range: Atlantic 



(West Indies) laternatus Garman, 1899 



6*. Anal organs 7 to 9. 

 c\ Gill rakers on first gill arch 7 or 8+14 to 16; width of first 3 anal 

 organs equal to width of last 3% to 4Vt anal organs; last or third 

 supra-abdominal organ in line with middle organ or only slightly 

 above it ; first organ extends above second and third a distance equal 

 to 1 or 1^2 times its width. Range: Atlantic (Bahama Islands; Gulf 



of Mexico) asteroides, new species 



c'. Gill rakers on first gill arch 5-f9 to 11; width of first 3 anal organs 

 equals width of last 3M> to 4Vt anal organs ; last or third supra-abdom- 

 inal organ above middle organ by a distance equal to its width ; first 

 organ extends above second organ a distance equal to ly^ to 2 times 



its width. Range : Philippine Islands triphanos, new species 



a*. Minute teeth present on vomer but absent on palatines; at nnterior end of 

 anal series of photophores no organ is located high above general line of 

 these organs. 

 d\ Posttemporal process of 3 spines, the middle one variable in length and 

 position, sometimes almost lacking but never longer than upper spine, 

 upper spine usually almost straight, pointing backward, variable in 

 length, often shorter than diameter of pupil or as long as diameter of 

 eye, upper spine alwiiys longer than lower spine, the latter usually 

 curved downward. 

 e\ Anal photophores about 1'- to 15 in adults ; photophores along ventral 

 margin of body usually without definite spaces between the various 

 series in large adults, while in smaller fish, between anal and sub- 

 caudal series, there may be no space or space may equal width of 1 to 

 3 of subcaudal organs, depending on size of specimen. Range : Pacific 

 (Japan; Philippines; Celebes Sea; Strait of Macassar; Great Austra- 

 lian Bight) ; Atlantic (Gulf of Guinea ?; Gulf of Mexico ?) ; Indian 



Ocean (Andaman Sea; Bay of Bengal) spinosus Giinthor, 1887 



c*. Anal photophores 4 in adults ; photophores along ventral margin of 

 body with a definite space between preanal and anal series and an- 

 other space between anal and subcaudal series, both spaces equal to 

 or greater than length of subcaudal series. Range: Philippine 



Islands fraseri Fowler, 1934 



d'. Posttemporal process of one main spine, which may be smooth or very 

 rough, spiny, or toothed below. 

 f. Gill rakers on first arch 4-|-7 or 8; main spine of posttemporal process 

 long and slender, without any trace of spine below it, length of this 

 spine equal to or greater than diameter of pupil ; space between anal 

 and subcaudal series of organs less than width of 3 subcaudal organs ; 

 anal photophores about 11 to 13. Range : Philippine Islands. 



unispinus, new species 

 f. Gill rakers 7 or 8+14 to 16 ; main spine of posttemporal process short 

 and heavy, its length less than diameter of pupil ; space between anal 

 and subcaudal series of organs greater than width of 3 subcaudal 

 organs; anal photophores about 11 or 12. Range: Pacific (Hawaiian 

 Islands; south of Minamitori Shima, Marcus Islands).
