Distribution: — According to C. CLAUS, 1874 b: „Atlantischer Ocean. Küste von Chile.‘‘
This writer does not specify the localities of the linds in the Atlantic. According to
G. \V. Müller, 1906 a and 1908, it is found in the Atlantic between lat. lu" 8. and lat. 58° 8.
and in the Indian Ocean. G. 8. BRADY, 1907, found it in the Antarctic as far south as lat. 59° S.

The specimens investigated by me were caught within the previously known area of
distribution.
