of that family hitherto known, and a new genus must be established 
for its reception. From Aphanopus, with which it agrees in having 
a dagger-shaped spine behind the vent, it differs in being possessed 
of scales and ventral fins; from Lepidopus it is distinguished by 
having two dorsals and scales, and by the absence of teeth from the 
palatine bones; from Trichiurus by having two dorsal fins, a well- 
developed caudal fin, and many-rayed ventral fins ; from Hpinnula 
by having a single lateral line, and by the separation of the dorsal 
fins ; from Thyrsites by having no teeth on the palatine bones, and 
by the separation of the dorsal fins ; from Dicrotus in having scales 
and many-rayed yentrals; and from Gempylus by the presence of 
scales and the absence of finlets. Moreover in the two known species 
of the last-named genus each ventral fin is represented by a spine. 
From the Sphyrenide, it may be mentioned in passing, it differs by 
the ventral fins being thoracic, and by the proximity of the dorsal 
fins. 
The following are the dimensions in inches of the principal parts 
of the specimen, which has been added to the collection of fishes at 
the British Museum :—
