beyond. Barbel fringed in its distal half, 2 the length of head. Seven very short gill- 
rakers on lower part of anterior arch. Dorsal 111, 26; spinous dorsal short and

Pogonophryne, Regan. 
Pogonophryne, Regan, Ann. Mag. Nat. Hist. (8) xu, 1914, p. 13. 
Differs from /7istiodraco in the wide interorbital region and the strongly depressed 
head, as broad as long and much broader than deep. 
18. Pogonophryne scotti, Regan (PI. v1, fig. 1). 
Pogonophryne scotti, Regan, Ann. Mag. Nat. Hist. (8) x1m, 1914, p. 13. 
Depth of body 4 in the length, length of head 25. Diameter of eye 53 in length 
of head, interorbital width 43. Maxillary extending to below middle of eye; lower 
jaw strongly projecting. Barbel blunt, papillose, shorter than eye. 10 very short 
eill-rakers on lower part of anterior arch. Dorsal m1, 25; spines low. Anal 18.

A single specimen, 290 mm. in total length, from the Ross Sea, 74° 25’ S., 
179° 3' E., 158 fathoms. 
A coloured drawing of a fish from the Bransfield Straits reproduced by Loénnberg 
(Swedish 8. Polar Exped. Fish. pl. 1, fig. 7) as Artedidraco skottsbergii seems rather 
to represent a Pogonophryne, perhaps even the species here described. 
This species is named in memory of Captain R. F. Scott, R.N., C.v.o.
