13. Artedidraco orianae, Regan (PI. v1, fig. 2). 
Artedidraco orianae, Regan, Ann. Mag. Nat. Hist. (8) xin, 1914, p. 12. 
Depth of body 5 to 53 in the length, length of head 22 to 3. Diameter of eye 
+ in the leneth of head, interorbital width 10. Maxillary extending to below anterior 
+ of eye. Barbel + length of head, club-shaped, with papillose distal expansion. 
Seven short gill-rakers on lower part of anterior arch. Dorsal 111—1v, 25; rays of soft 
dorsal decreasing from third or fourth; last adnate to caudal peduncle. Anal 17-18, 
separated by an interspace from caudal fin. Pectoral 17-rayed, 7 or ¢ length of head, 
extending to third or fourth ray of anal; pelvics as long, extending to vent or origin 
of anal. Caudal subtruncate. Five dark bars across back, extending upwards on the 
dorsal fins, the first at base of spmous dorsal, the second and fourth stronger than 
the rest; a spot on praeorbital, another on cheek; lower part of body irregularly 
spotted ; fins with series of spots. 
Two specimens, 80 mm. in total length, from off Cape Adare; depth 45 to 50 
fathoms ; bottom shingle. 
The species is named in honour of Mrs. E. A. Wilson. 
A, mirus, from South Georgia, described and figured by Lénnberg (Swedish South 
Polar Exped. Fish. p. 40, pl. iv, f 14), from a specimen of 114 mm., appears to differ 
from A. orianae in the deeper body (depth 4 in the length), larger head (2% in the 
length), longer barbel (4 the length of head), shorter paired fins (pectoral 3, pelvics 
3 to 2 length of head), higher soft dorsal with the middle rays longest and the last 
joined to the caudal fin, and in the absence of an interspace between anal and caudal. 
14. Artedidraco skottsbergii, Lonnberg (Pl. v, fig. 1). 
Artedidraco skottsbergii, Linnberg, Swedish South Polar Exped. Fish. p. 48, pl. rv, f. 15 
(1905); Vaillant, Expéd. Antarct. Frangaise, Poiss. p. 46 (1906). 
Depth of body 43 to 53 in the length, length of head 3 to 3}. Diameter of eye 
3 to 32 in the length of head, interorbital width about 14 to 20. Maxillary extending 
to below anterior 4 of eye. Barbel simple, smooth or finely papillose, less than $ 
diameter of eye. Seven gill-rakers on lower part of anterior arch. Dorsal mtv, 
24-26. Anal 17-20. Pectoral with 15-17 rays, to # length of head, extending to 
vent or origin of anal; pelvies shorter, barely reaching vent in young, not in adult. 
Caudal rounded or subtruncate. Body with numerous irregular dark spots; a series 
of blotches at base of dorsal fin sometimes continued on sides as bars; vertical fins 
with series of spots on the rays, those on posterior part of dorsal and anal and 
near upper and lower edges of caudal deep black ; pectorals barred. Vertebrae 15 + 23.
