Description 



D. 14-15; A. 14-15; P. 10-11; AO 6 (5-7) + 5 (4-6), total 11(10-12); gill rakers 6 (5) 4- 1 + 13 

 (14), total 20 (19-21 ); vertebrae 35. 



PLO much nearer pectoral base than to lateral line; VLO about midway between pelvic 

 base and lateral line. SAO.j one diameter, Pol and upper Pre two diameters, below lateral line. 

 First 3 Pre low and closely spaced, the fourth widely separate and usually much farther back 

 on base of caudal fin. Neither Dn or Vn much enlarged in males. 



Size: To about 40 mm. 



Least depth of capture: To 85 m at night. 



Distribution: In the central and eastern Pacific D.jenseni has been taken only in a rather 

 narrow band extending southeasterly from near the equator at about 165° to 110° W between 

 10° to 20° S (Fig. 97). Apparently it does not occur north or east of these limits. The type 

 locality is north of New Guinea. 



Diaphus malayanus 



Weber, 1913 



Fig. 102 — Diaphus malayanus, male. 31.4 mm. 



Description 



D. 15 (14-16); A. 15; P. 11 (10-12); AO 6 (5-7) + 4 (5), total 10 (11); gill rakers 6 -^ 1 + 12 

 (13), total 19 (20); vertebrae 34 (35). 



PLO and VLO much nearer pectoral and pelvic bases than to lateral line. SAOt. Pol, and 

 upper Pre at lateral line: Prc.j.j interspace equal to or greater than that between Prci and Prcs. 

 SAO in a steeply oblique straight line. AOai elevated to level of SAO2. 



Size: To 30 mm. 



Least depth of capture: To 85 m at night. 



Distribution: In the eastern Pacific, D. malayanus is infrequently taken in equatorial 

 waters between about 105° and 165° W (Fig. 97). The type locality is in Banda Sea.
