Distribution. — Various localities in the Mediterranean, from 10-300 

 fathoms; also Madeira and Cape Verds; off the south of Portugal, 

 1205 metres (Locard) ; off Havana in 450 fathoms, and Sand Key in 

 111 fathoms (Dall); Sombrero I. in 450 fathoms (Watson). Fossil in 

 the Pliocene of South Europe. 



Jeffreys gives the following notfcs on the animal of a specimen from 

 Station 26: "Body white; mantle folded back on the front of the 

 shell ; head hood-like, bilobed, with broad, pointed corners ; tentacles 

 large and thick, triangular; eyes black, subcutaneous, placed in front 

 at some distance apart; auricles in front, triangular, or bluntly 

 rounded behind; verge falcate, short. Animal like that of Bulla. 

 It crawls with considerable rapidity. The edges of the head and foot 

 in front are parallel or symmetrical, the former overlying the latter." 



ACTEON TORNATILIS (LinU.). 



Bulla tornatilis, Linne: Syst. ^'at., 10th ed., p. 728 (cf. Hanley, Ipsa 



Linn Conch., p. 212). 

 Actceon tornatilis, Linne: Pilsbry, Man. Conch., vol. xv, p. 152.

 Adventure Bank, 92 fathoms (with vars. minor, Monts., and siibulata, 

 S. Wood) ; Gulf of Tunis, 25-85 fathoms. 



Bistrihution. — Lofoten and Iceland to the ^I^lgean, from the shore- 

 line to 100 fathoms. Fossil in the Miocene and Pliocene of Europe. 



Several other station numbers appear on the boxes in. the British 

 Museum, but though I have sti'ong suspicions as to which cruise they 

 relate, 1 think it safer to leave them unrecorded. I suspect that the 

 Voluta luteofasciata of Muhlfbldt is a synonym.
