 Hyalcea lanceolata, Lesueur, 1813. Nouv. Bull. Soc. Philom. de 

 Paris, iii, p. 284, pi. v, fig. 3. 



This species has many synonyms, whose repetition is hardly 

 necessary. 



It is cosmopolitan in its distribution throughout the oceanic world. 

 Station XII. 246 fathoms. Thirteen specimens, more or less fragmentary, 

 though two or three contained the animal in a much con- 

 tracted state. 



Cavolinia, Abildgard. 

 (1) Cavolinia trispinosa (Lesueur). 



Hyalma trispinosa, Lesueur, 1821. In de Blainville, Diet. Hist. 

 Nat., xii, p. 82. 



Hyalcea mucronata, Quoy and Gaymard, 1827. In Ann. Sci. Nat., 

 X, p. 231, ph viii, B. 



Hyalcea depressa, Bivona, 1832. Ejemer. Scient. Sicil., pi. ii, tigs. 

 4,5. 



Cavolinia trispinosa, Locard, 1886. Prodrom. Conch. Franc, p. 22. 



Cavolinia {Diacria) trispinosa, Dall, 1889. In Bull. United States 

 Nat. Mus., xxxvii, p. 82, pi. Ixvi, fig. 115. 



I have compared our solitary, nearly perfect specimen with those 

 from the Atlantic in the British Museum (Nat. Hist.). 



This species is widely distributed, and is recorded from the east and 

 west coasts of the Atlantic, the Mediterranean, West Indies , Madeira 

 and Canary Isles, and Pacific Ocean. 



Station XII. 246 fathoms. One dead and one fragment. 



(2) Cavolinia inflexa (Lesueur). 



Hyalcea injiexa, Lesueur, 1813. Nouv. Bull. Soc. Philom., vol. iii, 

 p. 285, pi. V, fig. 4, A— D. 



Hyalma labiata, d'Orbigny, 1836. Voyage dans I'Amerique Meridion- 

 ale, vol. V, p. 104, pL vi, figs. 21-25. 



Cavolinia injiexa, Tesch., 1904. The Thecosomata and Gyinnoso- 

 mata of the Siboga Expedition, p. 43, pi. ii, figs. 54-63. 



This is a very variable species and has extensive synonymy : our 

 two shells seem to be referable to v. lahiata from an examination of 

 those so named in the British Museum (Nat. Hist.). 



Station XII. 246 fathoms. Two empty shells.
