(wrongly joined to interruptus Brod. (^Ximenes Gray), by 

 Tryon, both being natives of the west coast of Central 

 America), and C. planiliratus Sowb. This last has been 

 newly figured by Smith, it having been dredged in the 

 " Investigator" Expedition, off Calicut, west coast of 

 S. India, in 45 fathoms. {c.f.Ann. & Mag. N.H. Series 6, 

 vol. xiv., p. 159, 1894.) Our shell is more elegantly 

 spindle-shaped, and the spiral grooves are less distant and 

 puncturate. C. dictator is fusiform, with elevated spire, 

 acute apical whorls, attenuate base, straight sides, angled 

 periphery, dull white colour, everywhere dotted and painted 

 with dark brown ; these markings on the last whorl break 

 out into longitudinal brown flames, and there is another 

 suflusion of brown below the middle. This whorl is like- 

 wise transversely encircled with lined furrows, which are 

 closely puncturate. The mouth is narrow, outer lip simple. 

 One perfect specimen.

One of the most gracefully beautiful of the genus. 

 Several individuals were discovered by Mr. Townsend at 

 the locality above cited, none, however, in live condition, 

 and only two (one especially) showing coloration and
