3. Actceon globulinus (?) (Forbes).

Station 78. July 10, 1873. Lat. 37° 26' N., long. 25° 13' W. Off San Miguel, 

 Azores. 1000 fathoms. Volcanic mud. 



Habitat. — iEgean Sea, to 95 fathoms (Forbes) ; Mediterranean, 92 fathoms (Mon- 

 terosato). 



Fossil. — Middle Pliocene, Calabria (Seguenza). 



The specimen obtained from this station is only a fragment, and cannot, therefore, be considered 

 as quite satisfactorily determined, the more so that the peculiar spiral sculpture is never a very 

 constant feature. Forbes describes the shell as with whorls " simplicibus." This is not strictly 

 true, the whorls being minutely stippled, though in some cases the stippling is very faint. In 

 the Challenger specimen, which includes the whole body - whorl and mouth, the stippling is 

 exceptionally strong, but I believe the fragment belongs to this species. 



4. Action pusillus (?) (Forbes).

Station 23. March 15, 1873. Lat. 18° 24' N., long. 63° 28' W. Off Sombrero 

 Island, West Indies. 450 fathoms. Pteropod ooze. 



Habitat. — iEgean Sea, to 100 fathoms (Forbes) ; Mediterranean, 40 to 1456 fathoms 

 (Jeffreys) ; Palermo and San Vito, 90 to 210 fathoms (Monterosato) ; Madeira, 20 to 50 

 fathoms (Watson). 



Fossil. — Middle Pliocene, Calabria (Seguenza). 



The solitary specimen got by the Challenger is a mere fragment, and cannot be considered as 

 very certainly identified. Compared with the types in the British Museum, it has the spirals much 

 more numerous, and the apex is depressed. Dr Gwyn Jeffreys assures me that the species is pro- 

 bably the Tornatella depressa, Libassi, and is certainly =Acto3on nocc (J. Sow.). This opinion I have 

 at present no means of examining ; if it be correct, of course Sowerby's name, which dates from 

 1822, has priority.
