that shown by Smitu.*

Fig. 9.—Radula of Onychoteuthis ingens [H 925]. x 25. 
HIsTIOTEUTHID &. 
Mistioteuthis sp. juv. 
Locality.—Station 468, South Atlantic. Lat. 39° 48’ &, long. 2° 33’ E. 29th 
April 1904. 2645 fathoms. One specimen [H 940]. 
The specimen is somewhat damaged. The interbrachial membrane is slightly devel- 
oped. One arm shows the pigmented organ at the extremity, which, so far as I am aware, 
is characteristic (in this family) of the genus Histioteuthis, although it is not alluded 
to in the diagnosis either of Prerrer or Coun. In many respects it resembles the 
Challenger specimen called Histiopsis atlantica, which was also from the same region, 
but is pale and semi-transparent, whilst that was opaque and dull reddish in colour.

Locality.— Station 416, off Coats Land. Lat. 71° 22’ &., long. 18° 15’ W. 
Surface to 2300 fathoms. 17th March 1904. One specimen [H 938]. 
Previous Records. — Southern Ocean, lat. 46° 16’ S&S, long. 48° 27’ H.; off 
Martha’s Vineyard, U.S.A.; off Cape Mala, Gulf of Panama; off Cape Agulhas; 
Equatorial Indian Ocean. 
Professor CHun has adopted VeERRILL’s name Benthoteuthis megalops for this 
species, on the ground that “sheet 50 of the Zrans. Connect. Acad., vol. vi., in 
which VERRILL’s description is contained, bears (p. 399) the note ‘April 1885.” 
If my friend is content to accept this method of determining dates of publication, 
he may turn to sheet 34 of the Narratwe of the Challenger Expedition, vol. 1, 
first part, in which Hoyur’s description is contained, and he will find that it bears
