FIG. 3 . Araiophos gracilis . paratypes, standard length 30.5 and ca. 23 mm. 
(7.87, 6.55-8.19); interorbital width at center 
of eye 4.41 (4.73, ca. 4.9); upper jaw 13.2; pre- 
maxillary ca. 4.41; toothed portion of maxillary 
8.8; distance between tip of snout and dorsal 
origin 57.3 ( 55.2, 57.3 ), anal origin 48.5 (46.6- 
47.3, ca. 49.0, and in a specimen 28 mm. long 
from snout to caudal 48.2-50.0), ventral base 
ca. 44.1 ( ca. 39.4, 44.1); distance between first 
anal ray and base of middle caudal rays 51.4 
(52.0, 49.0, and in a specimen 28 mm. long 
from snout to caudal 50.0), last anal ray and 
base of middle caudal rays ca. 11.7 (11.0, 14.7— 
16.4), last dorsal ray and base of middle caudal 
rays 27.9 ( ca. 28.4, ca. 26.2), last dorsal ray and 
adipose fin 4.41 (6.3, — ), ventral bases and 
anal origin 5.87 (4.73, 4.9); least depth of 
caudal peduncle 5.87 (6.3, 4.9-6.55); dorsal 
base 11.7 (14.2?, 11.5-13.1); anal base 38.2 
(39.4, 31.1-32.8); adipose base 2.94 (6.3, — , 
and in a specimen 23 mm. in standard length 
4.34-6.52). 
Specimens all damaged to some extent, espe- 
cially in head and abdominal regions; both eyes 
of holotype lost, this specimen otherwise in fair 
condition. 
Body elongate, slender, compressed but with 
ventral surface flat between the second single 
abdominal IV photophore and the VAV group. 
No scales or scale pockets remaining. Pectoral 
fins of holotype reaching half-way between pec- 
toral and ventral bases; bases broadly peduncu- 
late. Ventral fins of holotype reaching anal ori- 
gin. Adipose fin with a relatively long base; 
very fragile and easily lost, leaving no trace ( ab- 
sent on 2 specimens, tearing loose on a third, 
possibly incomplete on holotype); its origin 
above a vertical from the third single AC pho- 
tophore, above end of anal fin. 
Specimens too small and fragile to determine 
presence or absence of pseudobranchiae. 
Teeth rather sparse, visible only under mag- 
nification, their presence or absence on vomer, 
palatines, pterygoids, or tongue impossible to 
determine but 1 specimen with a few minute 
teeth on roof of mouth anteriorly. 
Photophores as in generic diagnosis. ORB 
minute, close to premaxillary. The single OP 
double, relatively large. Only (2) small IV on 
isthmus posteriorly, well separated from abdom- 
inal IV (no photophores between isthmus and 
posterior end of pectoral base); abdominal iv 
commencing just behind pectoral base, organs of 
groups (first 3 and last 2 organs) small, the 4 
single organs much larger, well separated from 
one another. VAV occupying only anterior half 
of space between ventrals and anal, the individ- 
ual organs very small; anus below last, thus 
about half-way between ventral bases and anal
