Station VIII. February 12, 1873. Lat. 28° 3' 15" N., long. 17° 27' W. Gomera, 

 Canaries. 620 fathoms. Volcanic mud. 



Station 142. December 18, 1873. Lat. 35° 4' S., long. 18° 37' E. Cape of Good 

 Hope. 150 fathoms. Green sand. Bottom temperature 47°. 



Habitat. — West Africa. 35 fathoms. Sand. (Hinds.) 



The specimen from the Cape has the more elongated form of Marginella diadochus, Adams and 

 Reeve, but if the species be really different the locality suits Hinds' species better than that of Adams 

 and Reeve. Neither from the descriptions, however, nor from an examination of the shells, can I 

 consider the species of Adams and Reeve as distinct, and Hinds' name has priority. 



3. Marginella (Glabella) turbinata, Sowerby.

 Raine Island, Cape York, North-East Australia. 155 fathoms. Coral sand. 



Shell. — Small, obovate, with scarcely any spire, strong, porcellanous white, lustrous, 

 with an excessively narrow mouth, a truncate but not emarginate varixed toothless 

 outer lip, and four small folds on the sharp-pointed pillar. Sculpture : None but faint 

 lines of growth. Colour white, more or less translucent. Spire just perceptibly raised, 

 but visible rather by colour than form, the suture being a little more opaque than the 

 rest of the whorls. Apex minutely mamillate. Whorls 4, small, just perceptibly convex 

 on the spire ; the last is tumid, with a roundly conical and produced base. Suture barely
