material examined (14 specimens), the smallest male with glands was 59 mm, the smallest 

 female 36 mm. 



Size: To about 70 mm. 



Least depth of capture: Has been taken at night with 100 m of wire out. 



Distribution: Primarily from the North Atlantic and Arctic Oceans, and Mediterranean 

 Sea. Included as a remotely possible item in the Pacific fauna on the basis of one specimen 

 reported from the Arctic Ocean off Point Barrow, Alaska (Walters, 1955). Has not been re- 

 ported from there since, and not at all from the Pacific Ocean. 



Benthosema suborbitale

Fig. 34 — Benthosema suborbitale, male, 30.3 mm. 



Description 



D. 13 (12-14); A. 17 (16-19); P. 14 (13-15); AO 6 (5-7) -I- 5 (4-6), total 11 (10-12); gill rakers 3 

 (3-4) -h 1 -F 10 (9-10), total 13-15; vertebrae 34 (33-35). 



VLO high, near lateral line; VO^ much elevated and displaced forward to nearly over 

 VOi, nearly on a line with PVO and SAO,.j. PLO nearer pectoral base than to lateral line. So 

 present below orbital margin about under posterior margin of pupil. 



Supracaudal luminous gland single, large, extending from first procurrent caudal ray to 

 over half the distance to base of adipose fin. Infracaudal gland of 2 or 3 luminous scales either 

 lightly ringed with pigment or somewhat coalesced with slight indentations laterally. 



Size: To about 30 mm. 



Least depth of capture: Has been taken at night with 100 m of wire out. 



Distribution: A warm water, apparently circumglobal, species. In the eastern Pacific it 

 has been taken mostly in southern latitudes and from near Hawaii (Fig. 35). Two records, one 

 from about 28° N, 126° W, and one outside the Gulf of Tehuantepec, Mexico, may be question- 

 able; the specimens cannot now be found, and their capture localities lie far away from the 

 others. 



The only evidence of differentiation within this wide distribution is that specimens from 

 the Pacific tend to have a more prominent, usually larger, suborbital photophore than those 

 from the Atlantic Ocean.
