and Vn of females small, about equal in size, confluent behind nasal apparatus; both much 

 enlarged in males, the Dn resembling that of D. malayanus . Eye small, about 5 in head. 



Size: To about 40 mm. 



Least depth of capture: To 100 m at night. 



Distribution: In the central and eastern Pacific Diaphus schmidti has been taken in a 

 rather narrow band extending from Hawaii southeasterly to about 15° S, 104° W (Fig. 97). Its 

 pattern of capture localities is very similar to that oi Diaphus jenseni. The type locality is 

 north of Samoa.

Fig. 100— Diaphus regani. From Tuning (1932, p. 140, fig. 12). 



Description 



0.16(15-17); A. 16-17; P. 10-11; AO 6(5-7) -I- 5-6, total 12 (10-13); gill rakers 7 (8) -(- 1 + 

 13 (14), total 21 (22); vertebrae 36 (35-37). 



The elevation of the last few AOp will immediately justify this species. Dn and Vn but 

 little larger in adult males than in adult females. First AOa elevated nearly to level of SAO^ 

 and to nearly over second AOa. SAO series in a very steep line which passes slightly behind 

 VO,. 



Size: To about 60 mm. 



Least depth of capture: To 50 m at night. 



Distribution: Type locality. New Caledonia. In the eastern Pacific, D. regani is known 

 only from the equatorial region south of Hawaii between 150° and 160° W.
