Snout much produced, subtrihedral, pointed, nearly twice as long as the large eye, 

 which is two-ninths of the length of the head. Scales with from three to five strong 

 radiating keels, each keel terminating in a spine. Head covered all over wdth similar or 

 spiny tubercle-like scales, of which those along the infraorbital ridge and along a line on 

 each side of the crown of the head are the strongest. There are five scales in a transverse 

 series between the first dorsal and lateral line. Outer ventral ray produced into a short 

 filament. Length of abdomen equal to that of the head (without snout) in adult 

 specimens (20 inches long). 



Habitat. — South of Japan, Hyalonema-groujid ; off" Inosima, Station 232 ; depth, 

 345 fathoms. One specimen, 21^ inches long. 



This species is very closely allied to Macriirus parallelus, but the keels on the scales 

 diverge or radiate, whilst they are subparallel in the latter species. I see that the two 

 heads which the British Museum ^ received under the name of the present species belong 

 to a very distinct fish, evidently a new species, which may be described when more 

 complete materials are available. 



Macrurus australis.

Snout moderately produced, pointed, rather longer than the eye in old specimens, and 

 rather shorter in younger ones. Each scale with from twelve to eighteen parallel keels, 

 and with the margin more or less distinctly crenulated. Head covered entii-ely witli 

 rather irregularly shaped scales, of which those along the infraorbital crest and along 

 two indistinct lines on each side of the crown of the head are particularly rough. There 

 are four scales in a transverse series between the first dorsal fin and the lateral line. 

 Dorsal spine smooth. Abdomen, that is, distance of the vent from the isthmus, equal to 

 the distance of the end of the operculum from the anterior nostril in adult specimens.
