Varying considerably in size; of the two specimens from Stat. 40, the length of the 

 largest one is 35, that of the smallest only 24 Mill., though both have the lip expanded and 

 thickened and may be considered to be adult.

Of the two specimens, one is characteristic, being white with a broad brown band at the 

 base of each whorl, it seems to differ from the figures by one or two of the spirals being 

 slightly prominent, in the other specimen I see a few brown spots on the base of the whorls, 

 but no distinct band, and two spirals so much developed as to form one row of small tubercles 

 on the upper whorls, about halfway, and a second row, nearly concealed by the suture. Both 

 specimens are young. If adult they might be described as a variety, but now I prefer to make 

 only mention of these characters, as constituting individual aberrations of the type.

The name of this species has been written in very different manners; according to 

 Kiener, it has been named, but I think not described by Dufresne as C. coralinm, on Kiener's
