 Testa subcylindracea, turrito-subulata, fusca, nitida ; anfrac- 



tibus brevibus rotundatis, longitrorsum plico-costatis, superne 

 linea impressa contractatis ; costis rotundatis vel varicosis,

Shell somewhat cylindrical, subulate, turrited, shining, of a 

 rich brown ; whorls narrow, rounded, with longitudinal rounded 

 folds, girdled above, the interstices feebly striated ; last whorl 

 short, with a pale banding. Aperture small and contracted. 

 Columella short, twisted. 



I have examined a number of specimens of this shell, all 

 of which I refer to this species, and find them vary much in 

 the general and relative proportion of their outline and width 

 of whorls. 



St. Elena and Monte Christi, west coast of America ; in 

 from six to fifteen fathoms, sandy mud. 



74. T. fen est rata. (pi. xliv. f. 86.) Hinds, \. c. p. 153.

 inferne cancellatis; apice subpapillari ; anfractu ultimo quadrato 

 ad basin abrupte contractato ; apertura parva ; labio interno 

 subcalloso, producto. 



The superior series of tubercles is large and prominent, 

 and just beneath is accompanied by a second of smaller size, 

 the remainder of the whorl is cancellated by the crossing of 

 the two or three salient lines. The shell is of an uniform pale 

 dirty yellow colour.
