13. Artedidraco orianae, Regan (PL vi, fig. 2). 



Artedidraco orianae, Regan, Ann. Mag. Nat. Hist. (8) xm, 1914, p. 12. 



Depth of body 5 to 5j in the length, length of head 2;} to 3. Diameter of eye 

 3 }j in the length 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 in -iv, 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, ~ 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 mi the 

 dorsal tins, the first at base of spinous 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 (.'ape Adare ; depth 45 to 50 

 fathoms ; bottom shingle. 



The species is named in honour of Mrs. E. A. Wilson. 



A. minis, from South Georgia, described and figured by Lonnberg (Swedish South 

 Polar Exped. Fish. p. 40, pi. 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-f in the 

 length), longer barbel (^ the length of head), shorter paired fins (pectoral f, pelvics 

 \ to f 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 shottsbergii, Lonnberg (PI. v. fig. 1). i/ 



Artedidraco shottsbergii, Lonnberg, .Swedish South Polar Exped. Fish. p. 48, pi. iv, f. 15 

 (1905); Vaillant, Exped. Antaret. Francaise, Poiss. p. 46 (1906). 



Depth of body 4} to 5i in the length, length of head 3 to •'!',. Diameter of eye 

 3 to 3f in the length of head, interorbital width about 14 to 20. Maxillary extending 

 to below anterior \ of eye. Barbel simple, smooth or finely papillose, less than ^ 

 diameter of eye. Seven gill-rakers on lower part of anterior arch. Dorsal n-iv, 

 24-26. Anal 17-20. Pectoral with 15-17 rays, | to § length of head, extending to 

 vent or origin of anal ; pelvics 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.
