127. HISTIOBRANCHUS BATHYBIUS. 
Synaphobranchus bathybius Gunther, Ann. and Mag. Nat. Hist., xx, 445, 1877 ; ibid, 
Voy. Challenger, 254, pi. lxii, fig. b, 1887 (middle of North Pacific, South 
of Yedo ; midway between Cape of Good Hope and Kerguelen Island). 
Etymology : BaOvq, deep ; life. 
A specimen of this species was obtained by the Albatross in the depths 
of Bering Straits. 
128. HISTIOBRANCHUS INFERN ALIS. 
? Synaphobranchus bathybius Gunther, Ann. Mag. Nat. Hist., 1877, 445; Gunther, Chal- 
lenger, xxn, 254, pi. G2 (off Yedo ; North Pacific ; between Cape of Good 
Hope and Kerguelen Land). 
Histiobranchus infemalis Gill, Proc. U. S. Nat. Mus.,255, 1883. 
Habitat : Atlantic Ocean, latitude 38° 30' 30", longitude 69° 08' 25". 
Etymology: Latin, infernal, from its color. 
This species from the Atlantic agrees, so far as the scanty description 
goes, with Synaphobranchus bathybius Gunther (Ann. Mag. Nat. Hist., 
1877, 445), a species now known from various localities in the North 
Pacific and from the Antarctic Ocean south of the Cape of Good Hope. 
The only apparent difference is that the Atlantic form ( infemalis ) has 
the pectoral fins shorter than the other, perhaps an individual variation.
