"The close-set obtuse granules" with whicli the whorls are 

 described by Reeve as being covered, are situated upon somewhat 

 oblique ribs, which are 24 on the body-whorl. The columella is 

 straight in the middle and oblique in the region of the canal ; it 

 is smooth and coated with a callosity which is vei'y well defined. 

 The canal is narrow, deep, and recurved ; and the labrum is thick- 

 ened and furnished with about 7 teeth within. The length is 13 

 milliin., width 4|.

I am very doubtful with regard to the correct position of this 

 species. It seems to have some relationship to Natica as well as 

 to Becluzia. From the former it diifers in the absence of an um- 

 bilicus and in its liglit construction, and from the latter in the 

 arcuate columella. The spiral striae are very close together, very 

 faint and wavy. The lines of growth beneath the suture, especi- 

 ally in the last whorl, are elevated in a scale-like manner. Pro- 

 bably this shell has been invested by a tliin epidermis which has 

 been worn off by being rolled on the beach, where two specimens 

 were picked up by Mr. Brazier.
