The New /calami habitat has not hecn coniinned by local conchol- 

 Ogists. \Vatson remarks: " This species i> peculiar in coinhining a 

 very cylindrical form with a very narrowly reverted and truncated 

 pillar lip. Mr. K. A. Smith, who kindly examined my specimens, re- 

 marks that the British Museum 'specimens have the apical foramen 

 covered by a thin callosity,' which is not present in most of the 

 Challenger specimens. It seems to be very easily abraded."
