NOTE. 



To the species previously enumerated in this paper, the following (kindly 

 identified for me by Mr. S. R. Roberts, of Philadelphia, who has paid special 

 attention to the group) may be added : — 



Trivia globosa Gray. 



T. globosa Gray, Descr. Cat., p. 14, 1832. 

 Station 2, 805 fms. 



Most of the specimens of Trivia from great depths being dead and having 

 lost their freshness, a reasonable doubt exists as to theii- having lived at those 

 depths. 



Trivia oryza Lamarck. 

 T. pcdicidus Rumphius, Roberts Cat. No. 24. 

 Station 2, 805 fms. 



Trivia quadripunctata Gray. 



T. quadripunctata Gray, Zocil. Journ., III. 368, 1827. 



Yucatan Strait, 640 fms (fresh) ; Station 2, 805 fms.; Station 12, 177 fms.; 

 Barbados, 100 fms.; Sigsbee, off Havana, 80 fms. 



Trivia subrostrata Gray. 



T. subrostrata Gray, Zoul. Jom-n., III. p. 363, 1827. 

 Sigsbee, off Havana, in 80 and 175 fms.; Station 12, 177 fms. 



Trivia candidula Gaskoin. 



T. candidula Gaskoin, P. Z. S., 1835, p. 200. 



Yucatan Strait, 640 fms.; Station 21,287 fms.; Barbados, 100 fms.; Sigsbee. 

 off Havana, 119. 



Marginella haematita Kiener. 



Stations 10 and 11, in 37 fms. 



A fourth species of Pleurotomaria (P. Biimphii Schepman, Tijdschrift Nederl. 

 Dierkuiidige Vereeniging, IV. p. 162, Rotterdam, 1879) from the Moluccas has 

 been recently described, but I have not had access to the description, and I be- 

 lieve it has not yet been figured. Its height is 170.0, diam. 190.0, and breadth 

 of sinus 2.25 mm. It is an umbilicated species like P. Adansonmna.
