Type
locality
Not stated by
Holt & Tattersall (1905)
. They reported materials from four stations off
Ireland
, depth 199–382 fathoms (
363–696 m
). A rough estimate by the present author suggests that the stations are in the range of 52–
54° N
, 12–
13° W
.
Distribution
Previously reported from the NE-Atlantic and Mediterranean, 35–
58° N
,
13° W–
14° E
, depth
94–1200 m
, and from the NW-Pacific off
Japan
, 35–
37° N
, 137–
140° E
, depth
220–660 m

Frutos & Sorbe (2013)
sampled this species in the near-bottom water layer. The here documented records in the SE-Atlantic at 16̄
22° S
, 3̄
5° E
, depth 5161̄
5460 m
, represent a strong extension of the known bathymetrical range; within the Atlantic also a strong southward extension (see Discussion).
Statoliths
Statoliths mineralized with fluorite, diameter 133̄169 μm (n = 6 statoliths of
3 adults
).
