origin or slightly nearer the former; number 
usually (4), two specimens with (4) on one 
side and (5) on the other, holotype with (4) 
on both sides. First group of AC (two organs) 
above fifth to seventh anal rays, last group ( two 
organs ) behind anal fin but remote from caudal 
base; single organs much larger than individual 
organs of groups; number of single organs 
usually 3, 3 specimens with 3 on one side and 4 
on the other, holotype with 3 on both sides. 
Visible inside flattened belly of most speci- 
mens are two long, narrow, whitish or yellowish 
masses with the appearance of testes, extending 
forward to third or fourth single IV photophore. 
In addition to these structures at least 4 speci- 
mens (24, 27.5, 27.5, 31.5 mm.) also with 
ovaries; eggs minute except in 24 mm. speci- 
men, in which the ovaries are relatively large 
and contain eggs of different sizes. 
Color in alcohol yellowish, abdomen darker. 
Minute brown puncticulations along mid-line 
on tail, and outlining myomeres of tail. A nar- 
row vertical brown bar at extreme end of caudal 
peduncle. Some specimens with a short series of 
minute brown spots along anal base between 
first AC group and second single AC. Sparse 
brown pigment on top of head. A few minute 
brown spots on caudal rays, fins otherwise color- 
less. Inner bronzy iridescence and a few rela- 
tively large black chromatophores visible 
through abdominal wall laterally. 
Danaphos oculatus ( Garman ) 
MATERIAL EXAMINED: 7 specimens, 2 31.5 
and ca. 39 mm. in standard length, others 
slightly shorter but too damaged to measure, col- 
lected off the Mauna Loa lava flow, Hawaii, by 
Moore et al., June 3, 1950. 
Two specimens, standard length 36.5 and ca. 
36.5 mm., collected off the Mauna Loa lava flow, 
Hawaii, by Gosline et al., June 6, 1950. 
Cne specimen, standard length 33 mm., col- 
lected off the Mauna Loa lava flow, Hawaii, by 
Yamaguchi, June 6, 1950. 
Dorsal rays 6 (4 specimens). Anal rays (23?) 
24-25 (6 specimens). Pectoral rays ca. 18 and 
ca. 16 (2 specimens), upper 7 or 8 rays longer 
and much heavier than others, lowermost rays 
small and fine. Gill rakers on first arch 10-11 
-T 1 +2 = 13-14 (2 specimens), only 1 in 
angle. 
Measurements of 2 specimens expressed in 
per cent of the standard length (36.5 and 33 
mm.): depth 23.3, 21.2; head 23.3-24.6, 24.2; 
snout 5.47, 4.54; orbit (both vertical and hori- 
zontal) 8.2, 7.55; interorbital width too narrow 
to be measured accurately; upper jaw — , 15.1- 
16.6; premaxillary 8. 2-9.6, 7.55; toothed por- 
tion of maxillary 9.6-10.95, 9.06; tip of snout 
to dorsal origin 34.2, 34.8; to anal origin 46.5, 
45.4-46.9; to ventral base ca. 41.0, 37.8-39-3; 
distance between first anal ray and base of mid- 
dle caudal rays 52.0, 56.0-57.5; between last 
anal ray and base of middle caudal rays 8. 2-9.6, 
7.55; between last dorsal ray and middle caudal 
rays ca. 60.2, 53.0; least depth of caudal pedun- 
cle ca. 6.85, 7.55; dorsal base ca. 4.1, ca. 4.54; 
anal base ca. 43.8, 46.9; length of pectoral fin 
24.6, 24.2-25.7; length of ventral fin 8.2-9.6, 
9.06-10.6. 
A few large, round, thin scales remaining 
on several specimens. Anus below third VAV. 
slightly nearer anal fin than ventral bases. Dor- 
sal base very short. Anal origin close behind a 
vertical from last dorsal ray. No adipose fin. 
Pectorals, when complete, extending as far as 
third VAV photophore. Ventrals, when complete, 
reaching slightly past anal origin. Ventral bases 
below dorsal fin. 
Photophores: No upper OP. BR (6). IV com- 
plete on only 2 specimens; (3) + (4) on isth- 
mus, organs of first group smaller than those of 
second group; abdominal group 11, in 1 speci- 
men the first one separate, connection of others 
not determinable; abdominal series of a second 
specimen separated thus: 1 + (2) + (8), the 
gland joining the (2) obvious on outer surface 
of body, the (8) seen through damaged abdo- 
men to be joined to one another by a narrow 
gland, and each organ also joined to its counter- 
part on other side of body; total IV 17-18. VAV 
(5) in all 10 specimens. AC (3) + 15 + (4) 
+ 1 = 23 in 5 specimens, (4) + 15 + (4) + 1 
= 24 in 1 specimen, (3) + 14 + ( 4 ) + 1 = 22 
in 1 specimen, (3) + 16 + (4) + 1 = 24 in 1 
specimen, and 1 specimen with (3) + l6+(4) 
+ 1 = 24 on one side, (3) + 17 + (4) + 1 = 25 
on other side; damaged in 1 specimen. OA (2) 
+ 4 = 6, complete on only 1 specimen.
