The head of this individual, reckoned to the last of the gill 
openings, is thus contained 7.3 times in the total length of the body, 
and the height of the body 11.5 times. In the typical specimen, 
which was likewise a female, and whose total length was about 
1580 mm., the height of the body was said to be contained nearly 
15 times in the total length of the body, but as that specimen was 
wizened and shrunk, and wanted the end of the tail, the height was 
certainly somewhat greater originally. 
In our specimen, it proved to be the enormous liver with its two 
large lobes, extending through nearly half the length of the body, 
which contributed to the comparatively great height of the body; and 
the statement made by Goode and Bean in their last great work, 
Ocean Ichthyology,? that one of the family characteristics is ,Body 
1 The commencement of the dorsal fin is, in front, almost imperceptible, as its 
commencement is only indicated by some scales which are inconsiderably larger 
than the other scales of the body.
